I would like to develop an app that will be used for measuring irregular shapes on your android device's touch screen. For example, I have a MotoG3 phone and its screen dimensions are 142.1 x 72.4 x 11.6 mm. I place an eraser of dimensions 15mm* 16mm* 12mm on my phone. I want to build an app which will sense the object placed on its screen and give the dimensions of the object or sense the area covered by the object on the phone. May I know the Mathematical formula/algorithm to get the full area of the touch screen space?

I have developed applications in J2ME and for Android. I am planning to learn and develop hybrid applications using HTML5/JavaScript/jQuery or AngularJS. Is there a place where I can get information on the different frameworks and how hybrid architecture should be used? Any books for beginners in hybrid development?

i am searching for a way to extend my native iOS App (written in Objective-C) with HTML5/CSS/JS So i could write parts of my App´s Code in HTML like a basic shop or similar where code in HTML already exists. But i don´t want to destroy the great native like look and feel or make users think they left the app and entered a scaled-down version of Safari or similar. So they won´t even feel they are on external HTML on the net. I want a HTML page inside my App but with full advantages of device like animations, transitions, preloading, no borders. Maybe even make use of device functions like accessing camera, sound and so on. How could this be done if possible? thanks in advance

I would like to build an app and collect some events from the app, and then show some event statistics like frequency, duration etc. I`ve just investigated the aws Cognito web service, but it stores only a set of key-value pairs of a limited total size. I can build, of course, my own REST web service on the top of the database and store all my events there. But I wonder if there are some aws web service(s) that I can leverage to build such a solution. (In case if someone familiar with Azure, it would be nice to see the possible solution there too!) Any ideas, suggestions?

I have a samsung note pro 12.2 and was wondering how I could inspect element on the browser without connecting to a computer? I understand for smaller devices this makes sense to connect to a computer but for a tablet this size or even a 10 inch, the real estate of the screen would allow me to have an efficient workflow. If this is possible, I would be able to design on the go making it so much easier than carrying around my laptop. Perhaps there is a special browser to use?

We have a mobile app that is our main product. We need to provide a different price (not just currency conversion) for it for each country store. As we found out (please let me know if this is wrong), the only way to do this is to upload the app separately on each country store (i.e. separate apps). Is there an easy way to manage these uploads to the 10+ stores we're targeting. By managing I mean uploading the release itself on all needed country stores as well as monitoring all apps KPIs like number of installs.

I'm not sure what I'm trying to do is possible but here goes... I'm looking to create a library of services to use within MvvmCross applications, the majority of services will probably use plugins either written by me or a third party. Rather than having to get the applications using the service library to go and get all the individual NuGet packages for these plugin dependencies i'd prefer if either, 1) The plugins could be built into the library assembly. 2) Or I could supply all the plugins required by the library in a single NuGet package so that this is the only one the app has to pull in to use the library. My question is can plugins be wrapped up like this?

We've just successfully created an accessibility app for android (think screen reader) that works across all applications without needing to first launch a specific app, via the [accessibility service](http://developer.android.com/guide/topics/ui/accessibility/services.html#manifest).

I've recently completed an Android app in Xamarin and am now working through creating an iOS application. I'm not sure if I've missed something extremely basic here, but I'm having trouble understanding how you transition from one screen to another. In the MultiScreen demo app, this is achieved with a navigation controller and segue. I also saw the code sample which shows you to do this manually, calling the: ``` NavigationController.PushViewController(YourView, true); ``` And this works fine assuming you want to be able to navigate between the two. The first thing my users see is a login screen. If the user successfully logs in, I want to send them to a home screen. As you can imagine, it makes no sense that you would 'go back' to the login page. I've seen it is possible to hide the navigation bar, but I just wanted to check first... Is there an alternative way to transition to the home page without using a NavigationController ? Thank you in advance.

I have to implement a reminder - make the note, then store it in local DB and then make the notification when time comes. I have no experience in mobile development so I'm asking what's better - to implement some time manager that will invoke notifications instantly or store the notifications "as is" to let them be activated by themselves. What is good approach? EDIT: I forgot to mention, that I use Xamarin and I've already implemented cross-platform notifications, but now the problem is to choose right way to store and handle them

I noticed that Voice Control can control phone application using names, nicknames from address book. It can also play music list from default iOS music player app. I would like in my app to register new voice commands for this Voice Control engine and handle some actions based on recognized commands. I was searching in developer documentations but can't find anything like that. Am I missing something?

I have problems with getting `new Date();` to work properly in a mobile app (Cordova/Phonegap). Some suggested that iPhones and Androids requires specific format other then the one used by default by Javascript, like this one: mm/dd/yyyy hh:mm:ss. Thing is, my app needs to receive from the client its current time (now) and then send it to the server. How can I make `new Date();` so it comes out with mm/dd/yyyy hh:mm:ss format? As I see Date() can't accept a format as argument.

But when i stop recording on any app screen, it crashes the surfaceflinger library. Here the code to setup the recorder : ``` mMediaRecorder = new MediaRecorder(); mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE); mMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT); mMediaRecorder.setVideoEncodingBitRate(700 * 1000); mMediaRecorder.setVideoFrameRate(30); mMediaRecorder.setVideoSize(recordDisplayWidth, recordDisplayHeight); mMediaRecorder.prepare(); mMediaProjection.createVirtualDisplay(mFragment.getActivity().getLocalClassName(), recordDisplayWidth, recordDisplayHeight, mScreenDensity, DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR, mMediaRecorder.getSurface(), null, null) mMediaRecorder.start(); ``` The recording starts successfully, but when i do mMediaRecorder.stop(), surfaceflinger crashes. Here is the log for the crash : ``` 02-10 11:35:01.180 4807-9696/? D/OMX-VENC-720p﹕ close m_pipe_in(27) 02-10 11:35:01.180 4807-9696/?

So, we started using gitflow workflow with our server side as well as mobile development. It works out really well with server side code, since there is test coverage and with build automation, feature branches get merged into development branch as soon as they are tested ok. Unlike mobile development, since the changes are live as soon as you wish to (no time to deploy apart from build and testing), you can quickly test if there are any bugs in code you pushed and quickly make changes. So this workflow works out really great for server side development. However we are facing issues with mobile development with this workflow. With gitflow workflow, we have three persistent branches, namely development, staging and master. Code on master branch goes to our play store app, we have another closed beta google play store app for staging which is available only to our team members and we use crashlytics beta to distribute latest development branch code only to developers from our team. Whenever someone starts working on new feature, that person creates feature branch forked from master (previously we used to fork it from development) and once the feature is ready, creates a pull request into development. Everyday, we review pull requests and ones that are ok are merged into development. Now there are two major issues that we are facing with this workflow. One is that suppose we merged some feature into development and later figured out that there are lot of bugs in it. Now it can’t be pushed further, whole development cycle is stuck because that code is already merged with development. This is the reason we started forking feature branches from master rather than development as at least individual feature branches will have fully working code. One way is that each feature can be separately distributed to team members to test and only then will be merged to development but it's very cumbersome. So can this problem be solved with a different workflow? Another problem is with conflicts in code. Since base code with every feature branch is from master branch and it has to be merged with development, there are lot of conflicts nowadays. Earlier when we used to fork from development, we used to regularly merge development branch with feature branches people are working on so there were no conflicts but can’t do that anymore. So now to fix conflicts, we create another temporary branch from feature branch with which we merge dev code, fix conflicts and put that as pull request which is again little cumbersome. This all looks like problem of gitflow workflow not suiting well for mobile development. Is there a better workflow for mobile development that people have adopted or even some practices that can be followed to solve these problems?

I would like to ask for a guide on how can I develop cross platform applications using Xamarin in Centos 6. I spent the whole day following this: [Install Mono and Monodevelop on CentOS 5.x/6.x](https://stackoverflow.com/questions/16900575/install-mono-and-monodevelop-on-centos-5-x-6-x) So I can install Mono and Monodevelop. But now, I am blocked because I can't understand how I am going to use this tools so I can create Android and iOS applications. Can I do Xamarin development in Centos 6? If yes, I would also like to ask for good resources because it seems that there are very few tutorials for Xamarin especially in Centos.

First off, I know very little about android development, I am just getting started. What is the Minimum SDK choice that you get when creating a project in android studio? Is there a downside to using an older one? And if I follow a tutorial is it essential that I use the same one so I can follow along? Thanks.

I recently learned how to build a mobile application using Ionic and needed a backend so I decided to use the Backand framework. I am developing in Visual Studio and everything works great when run from the emulator, and all service calls work perfectly, however when I attempt to perform the same service (POST) operations from an Android Device I get the following error. Refused to connect to 'https: //api.backand.com/1/objects/player/'; because it violates the following Content Security Policy directive: "default-src 'self' data: gap: [https://ssl.gstatic.com](https://ssl.gstatic.com) 'unsafe-eval I found a similar issue in which the solution was that I may need to reference the servers address in index.html 's meta tag `<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https: //ssl.gstatic.com 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; connect-src https://api.backand.com:*">` This however crashes the application and now I have hit a dead end as to where I should go from here. I would be happy to provide any more information that may be necessary, any help would be greatly appreciated! Thanks

I'm developing a mobile app with Cordova (in Intel XDK) which is a list of buttons that launches other apps. So far I've managed to launch phone app (`href="tel://"`), sms (`href="sms://`) and google website in browser (`href="http://google.com"`). I've found a plugin for starting apps: [https://github.com/lampaa/com.lampa.startapp](https://github.com/lampaa/com.lampa.startapp) but basing on guide provided there I can launch an app with code like this (example) : ``` navigator.startApp.start([["app.com.name", "app.com.name.Activity"], [{"product_id":"100"}]], ...); ``` But how can I find those full app names (these `app.com.name` strings) ? I need names for these apps (or way how to open them): - - - - - - Just to remind: I don't want to sync any data between these apps and mine - I just want simply to launch it via my app. If You have other solutions - I'm open for any suggestions.

With the free Xamarian with Visual Studio does a Windows Developer using a Windows Machine have to buy Iphones, Ipads & Andoid devices to convert c# Windows into IOS or Android? When trying to create C# from withing Visual Studio / Xamarian it is asking me to pair a mac that I do not have. Is it mandatory to use physical devices rather than emulators? Thank You for this opportunity!

Do I need iOS or Android device(s) to write applications using Visual Studio with Xamarin

I am new to Swift and is currently developing an Multipeer Connectivity app for a course project. The app also has an online log-in feature that stores each user information in Firebase(the backend support). Once the app gets wifi connection, I want to have a 'friends list' feature in my app and add other app users to this list from the nearby devices found. So far, the only way I could think of is to associate the peerID with an existing app user from Firebase. However, according to the documentation, peerID seems to be associated with the device itself so if two different users used the same device to sign in, this approach can't really work. Is there a better way to achieve my goal?

I've googled and not able to find a good answer. I do not have a Mac at the moment and have to develop an app using C++. Do I need any stuff additional to Visual Studio? I mean I'm planning to use Xamarin and do I need an Xcode or at least Mac without Xcode?

I'm investigating ways to securely share small amounts of data between apps, ideally I would limit this to apps signed by the same developer. We wouldn't have the concept of a central hub app so using intents or content providers doesn't seem to work since there would be no logical place for the data to sit. Ideally we need a mechanism like the keychain on iOS. I know that a shared user ID is a potential option but this seems dangerous since it involves apps sharing a process. Does anyone have any ideas on a good approach to have some simple shared storage between apps that is secure and doesn't involve one app owning the data? I was coming to the conclusion that the way to do this was to put encrypted data into shared preferences. However I've just seen that the World Readable and World Writable modes have been deprecated so I'm questioning whether this would be a good long term solution, does that deprecation mean sharing files between apps like this is now not a viable option?

I developed a CustomKeyboard, to be used in any application for Android, that the pressure of a key opens a running Activity recognition. At the end of the recognition the Activity closes and I need to write the recognized text in EditText that opened the keyboard (any EditText such as Sms App), but I can not because it is probably no longer active. How can I get a reference to the active EditText that opened my keyboard, and then use it later to write the recognized text? EDIT: sorry... the code is below ``` public class SoftKeyboard extends InputMethodService implements KeyboardView.OnKeyboardActionListener{ private KeyboardView _kv; private Keyboard _keyboard; private InputMethodManager _inputMethodManager; @Override public View onCreateInputView() { _kv = (KeyboardView)getLayoutInflater().inflate(R.layout.keyboard, null); _kv.setKeyboard(_keyboard); _kv.setOnKeyboardActionListener(this); registerReceiver(receiver, new IntentFilter(Const.NOTIFICATION)); return _kv; } @Override public void onKey(int primaryCode, int[] keyCodes) { InputConnection ic = getCurrentInputConnection(); switch(primaryCode){ case 1010: // starts View for Barcode scanning _lastEditorInfo = getCurrentInputEditorInfo(); _lastBarcode = null; BarcodeActivity mainactivity = new BarcodeActivity(); Intent dialogIntent = new Intent(SoftKeyboard.this, BarcodeActivity.class); dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(dialogIntent); Log.i("Key","Open BarCode Activity"); //ic.commitText(String.valueOf(_lastBarcode),1); new WaitForBarcode(ic, _inputMethodManager).execute(""); break; ... } } private class WaitForBarcode extends AsyncTask<String, Void, String> { private InputConnection _icn; private InputMethodManager _inputMethodManager; public WaitForBarcode(InputConnection icn, InputMethodManager inputMethodManager) { _icn = icn; _inputMethodManager = inputMethodManager; } @Override protected void onPostExecute(String result) { // might want to change "executed" for the returned string passed // into onPostExecute() but that is upto you _inputMethodManager.showSoftInputFromInputMethod(getToken(), InputMethodManager.SHOW_IMPLICIT); _inputMethodManager.restartInput(_kv); _kv.setActivated(true); Log.i("Barcode-last", _lastBarcode); _icn = getCurrentInputConnection(); _icn.commitText(String.valueOf(_lastBarcode),1); } }; ``` in onKey() I start the BarcodeActivity, this one work's perfectly. At the onPostExecute I have right barcode in the _lastBarcode field, but when I try to post on EditText is not there ;( Putting a delay of 1sec on doInBackground (just to give to the System time to close previous Activity) and forcing to re-open keyboard, the commitText works. Code is: ``` private class WaitForBarcode extends AsyncTask<String, Void, String> { private InputConnection _icn; private InputMethodManager _inputMethodManager; public WaitForBarcode(InputConnection icn, InputMethodManager inputMethodManager) { _icn = icn; _inputMethodManager = inputMethodManager; } @Override protected String doInBackground(String... params) { while (_lastBarcode == null) { try { Thread.sleep(1000); } catch (InterruptedException e) { Thread.interrupted(); } } return _lastBarcode; } @Override protected void onPostExecute(String result) { // might want to change "executed" for the returned string passed // into onPostExecute() but that is upto you _inputMethodManager.showSoftInputFromInputMethod(getToken(), InputMethodManager.SHOW_IMPLICIT); _inputMethodManager.restartInput(_kv); getInputView().setActivated(true); Log.i("Barcode-last", _lastBarcode); final InputConnection ic = getCurrentInputConnection(); if (ic != null && _lastBarcode != null) { ic.beginBatchEdit(); ic.commitText(_lastBarcode, 0); ic.endBatchEdit(); } } ```

I need to implement the following: I have a page on which user enters an email. Every time text changes, I have to check whether the user exists in a DB and based on that information, I should set the text of the button to either "Sign up" or "Sign in". The problem is, that this DB request may take a couple of seconds (the reason is irrelevant) and the API is async, so event handler will be decorated with `async`, and since mail entry may change several times, this handler will be called several times before any one will end. So I'll have concurrent API requests and then, potentially, concurrent attempts to change the button text and that may not end well. I thought of something like this: ``` private async void OnTextChanged(object sender, TextChangedEventArgs e) { mailEntry.TextChanged -= OnTextChanged; ... submitButton.Text = (await api.AccountExistAsync(mailEntry.Text)).IsRegistered ? "Sign in" : "Sign up"; ... mailEntry.TextChanged += OnTextChanged; } ``` But a problem with this design, is that, say, a valid email was entered between `-= OnTextChanged` and `+= OnTextChanged`, in which case it'll never be checked. My question is, what is the right way to implement what I'm trying to achieve? Thanks in advance.

So I want when the app is opened, that login page will be launched. How do I get started? Do i need to use auto-launch? or Do i need to set the page manually like using openURL etc? Is there typescript alternative for this: ``` // my-page.js var OpenUrl = require("nativescript-openurl"); OpenUrl("http://www.master-technology.com"); ``` Or should I use WebView? If so, how to make it launch automatically? Thanks.

If I use Nexus 5x AVD, the path is "/storage/1D15-3A1B/". When I use Nexus 6p AVD, the path is "/storage/4679-1802/". So how can I dynamically write the sdcard path in program to locate the file in external sdcard? Thank you!

Is there an easy way to get the javascript functionality out of React Native without the view portion? I looked through the source and found what seems to be the relevant pieces (namely the [cxxreact](https://github.com/facebook/react-native/tree/3940f06211faf4fc34270d5cf2c5d57d43ed762e/ReactCommon/cxxreact) package), but am having a hard time following how it fits together. I am trying to run javascript in a native app without a webview. I've found J2V8 and AndroidJSCore, but they seem like they're going to require a lot of work to make generic enough to run arbitrary javascript. I believe React Native already solved this (especially surrounding api calls) and would like to reuse that portion. Is there anyone who has done something similar or can point me to something more full-featured than just J2V8 or AndroidJSCore?

In my game i have timer variables for every thing that happen in my game for example timer for counting seconds till i create an enemy and deploy it and timer for any enemy to shoot .. my point here is that i am using a lot of variables of type long. ``` long timeToEnemyShoot = System.nanoTime(); while (true){ update(); } public void update(){ if( System.nanoTime() - timeToEnemyShoot) / 1000000 >= 1000 ){ enemy.shoot(); } ``` and just imagine that there's more than 15 variable like that ! and i think this is not a good way to manage time. So is there any other efficient way ?

I would like to center the active tab in the scrollable navbar. Currently I have a scrollable horizontal view but am stuck on updating the view. I am looking at other [examples such as here on github](https://github.com/ptomasroos/react-native-scrollable-tab-view/pull/302). I would love some feedback on creating the _updateView method, there seems to be more to solving this problem than simply adding a few flexbox rules. Here is my component code. ``` export default class MenuNavBar extends Component { static propTypes: { goToPage: React.PropTypes.func, activeTab: React.PropTypes.number, tabs: React.PropTypes.array, } constructor(props) { super(props) var screenWidth = Dimensions.get('window').width; this.state = { paddingLeft: 5, paddingRight: 5, titleMenuWidth: screenWidth - 100 }; this._onScroll = this._onScroll.bind(this); this._onClickMenu = this._onClickMenu.bind(this); componentDidMount() { this._listener = this.props.scrollValue.addListener(this.setAnimationValue.bind(this)); } _onClickMenu(index) { this.props.goToPage(index); this._updateView(index); } _updateView(index) { var navContainerWidth = Dimensions.get('window').width - 100; console.log('navContainerWidth', navContainerWidth) } _onTabLayout(event, i) { this.menuTabs[i] = (this.menuTabs[i]) ? this.menuTabs[i] : event.nativeEvent.layout.width; } _onScroll(event) { let { contentSize, contentInset, contentOffset, layoutMeasurement, } = event.nativeEvent; } _renderMain() { return ( <NavigationBar title={ <ScrollView ref='menuScrollView' onScroll={this._onScroll} onLayout={this._onLayout} style={{width: this.state._titleMenuWidth}} horizontal={true} showsHorizontalScrollIndicator={false}> {this.props.tabs.map((tab, i) => { if (i == 0) { ref_name = 'tab_' + i; component_style = { paddingTop: 5, paddingBottom: 5, paddingLeft: this.state.paddingLeft, paddingRight: 5, }; } else if (i == this.props.tabs.length - 1) { ref_name = 'tab_' + i; component_style = { paddingTop: 5, paddingBottom: 5, paddingLeft: 5, paddingRight: this.state.paddingRight, }; } else { ref_name = "tab_" + i; component_style = styles.navbarMenuButton; } return <TouchableOpacity ref={ref_name} key={tab} onLayout={(event) => this._onTabLayout(event, i)} onPress={() => this._onClickMenu(i)} style={component_style}> <Text style={this.props.activeTab === i ? styles.navbarMenuTextActive : styles.navbarMenuText}>{tab}</Text> </TouchableOpacity>; })} </ScrollView> } leftButton={ <View> <Image source={require('../../assets/imgs/logo.png')} style={styles.navbarLogo} /> </View> } style={styles.headerStyle} statusBar={{tintColor: '#6C0104'}} /> ); } _renderTrend() { return ( <NavigationBar title={ <ScrollView ref='menuScrollView' onScroll={this._onScroll} onLayout={this._onLayout} style={{width: titleMenuWidth}} horizontal={true} showsHorizontalScrollIndicator={false}> {this.props.tabs.map((tab, i) => { if (i == 0) { ref_name = 'tab_' + i; component_style = { paddingTop: 5, paddingBottom: 5, paddingLeft: this.state.paddingLeft, paddingRight: 5, }; } else if (i == this.props.tabs.length - 1) { ref_name = 'tab_' + i; component_style = { paddingTop: 5, paddingBottom: 5, paddingLeft: 5, paddingRight: this.state.paddingRight, }; } else { ref_name = "tab_" + i; component_style = styles.navbarMenuButton; } return <TouchableOpacity ref={ref_name} key={tab} onLayout={(event) => this._onTabLayout(event, i)} onPress={() => this._onClickMenu(i)} style={component_style}> <Text style={this.props.activeTab === i ? styles.navbarMenuTextActive : styles.navbarMenuText}>{tab}</Text> </TouchableOpacity>; })} </ScrollView> } leftButton={ <View> <Image source={require('../../assets/imgs/logo.png')} style={styles.navbarLogo} /> </View> } rightButton={ <View> <TouchableOpacity onPress={() => Actions.country()}> <Image source={require('../../assets/imgs/ic_world.png')} style={styles.worldLogo} /> </TouchableOpacity> </View> } style={styles.headerStyle} statusBar={{tintColor: '#6C0104'}} /> ); } render() { var screenWidth = Dimensions.get('window').width; var titleMenuWidth = screenWidth - 100; return (this.props.mode == 'main') ? this._renderMain() : this._renderTrend(); } } ``` P.S. I will update this question to be more clear as I fully understand it better.

My android studio was working just fine, I don't remember updating anything but I must have changed something unknowingly because all of a sudden I'm getting a nullpointerexception with my project and when starting android studio I get the IDE internal error occurred. I tried making a new project and I keep getting the nullpointerexception: null. I have tried the methods suggested to other people who asked the same question (updating android studio, clearing the avd folder under android...) and none of them worked for me and that's why I asked this question hoping for a solution that might work for me.

I'm trying to move a custom view that is in my main activity with a single touch input, however the x/y coordinates for the event are offset due to the action bar. [GIF of problem](https://really.neato.site/data/G9qot4N7hJJLeyMZ.gif) I'm trying to find a way to negate the size of the action bar to the y coordinate but nothing seems to be working. I've subtracting the difference in the parent view and my custom view's size from the y coordinate `getRootView().getHeight() - getHeight()` but the value is incorrect. Can anyone point me in the right direction? The custom view: ``` public class SampleView extends View { private Paint paint; private Path path = new Path(); public SampleView(Context context) { super(context); init(); } public SampleView(Context context, AttributeSet attrs) { super(context, attrs); init(); } private void init() { paint = new Paint(); paint.setColor(Color.RED); paint.setStyle(Paint.Style.STROKE); paint.setStrokeWidth(10); } @Override protected void onDraw(Canvas canvas) { canvas.drawPath(path, paint); } @Override public boolean onTouchEvent(MotionEvent event) { final int x = (int) event.getRawX(); final int y = (int) event.getRawY(); switch(event.getActionMasked()) { case MotionEvent.ACTION_DOWN: { path.moveTo(x, y); break; } case MotionEvent.ACTION_MOVE: { path.lineTo(x, y); break; } } invalidate(); return true; } } ``` I haven't touched my MainActivity, but have added in the XML for activity_main my custom view: ``` <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.caseyweed.sample.MainActivity"> <com.caseyweed.sample.SampleView android:layout_width="match_parent" android:layout_height="match_parent" /> </RelativeLayout> ```

I found that it is possible to make "knock to unlock" [http://www.knocktounlock.com/](http://www.knocktounlock.com/) using accelerometer. I found this for swift: [Swift CoreMotion detect Tap or Knock on device while in background](https://stackoverflow.com/questions/30619778/swift-coremotion-detect-tap-or-knock-on-device-while-in-background) Is there anyone who is interested in making it for android? I am really new on mobile development. I would appreciate it so much if you share some source code in android java! Best regards, Mudin

I'm basically an Android developer, now learning iOS development using Swift. My Question is , What is the correct way to achieve horizontal paging in iOS , which can be used to implement "Card Swiping" , in which the card has text view which changes its text . What I mean is , the card and the text view should move together when we swipe horizontally and the next card should have the next text view. And I'll have an array of quotes and the number of pages should depend on the length of this array. So wanted to know what to use exactly , a "ScrollView" or a "CollectionView" or a "TableView"? And How to use it ?

I'm a UE4 newbie and am starting to make my very first mobile game with this engine. I'm really having trouble with implementing the event as described in the title. Basically, there are a bunch of tiles on screen. All I want is when the user touches any tile and hold his finger and drag it across other tiles, all the 'touched' tiles will change color. What Action/Axis Mappings do I need to add in Engine-Input? I also tried using `TilekMesh->OnInputTouchEnter.AddDynamic(this, &AMyProjectBlock::OnFingerPressedBlock);`, but even when I touch-hold and drag, the tiles do not seem to change color. But when I use `OnInputTouchBegin` instead, it works successfully but I don't want to singly touch and let go each tile. Any help would be greatly appreciated.

Now, Iam working on a project to build an app with content blocker extension which will be integrated with safari to block some websites from loading and this will be controlled by parents to safe thier child s from accessing those sites. The challenge which I face that childs may disable it from safari setting by swipe the content blocker button in settings or delete the app. How I allow parents to protect the app?

I have to develop a RESTful API for a mobile application and I have some concerns about the flow of the communication between those parts. I'm new to the API development for mobile devices and OAuth. The project in common should work this way: - - I found a similar question here [OAuth on REST API for mobile app](https://stackoverflow.com/questions/15648171/oauth-on-rest-api-for-mobile-app) and I prefer the first solution from it, but I have some questions about the security of this solution. 1) Should I use OAuth2 for the API? I'm not sure it's a good idea just to send the user's Google ID to the API to get user's data. 2) How can I check on the server that the Google ID is correct and actual? Or it's not important at all? I'm thinking about this scenario, but I'm not sure it's the best solution: 1) The user logs in on the mobile application for the first time using his Google Account. 2) The mobile application receives Google ID and some additional information. 3) The mobile application sends the Google ID to the server. 4) The server uses OAuth2. It creates an account for the user (saving the Google ID in the database) and returns an access token to the mobile application. 5) The mobile application stores the access token locally and uses it for requests to the server. Once the access token expires, the user has to login in the mobile application again using his Google account. I have some concerns about using just Google ID for generating a token. I mean, anybody can just use somebody's Google ID to create a token. Bad idea :( Also should I use JWT better as a token? Thanks for your help!

I'm trying to figure out if there is a protocol for wireless phone to phone communication (so not WIFI) where an application can determine that another phone with the same application is in the same room (or a couple meters) and transfer data between the applications. Bluetooth would work but I want the application to pre-establish the handshake instead of requiring the Bluetooth handshake. NFC would be perfect if the range was more than 10cm. Is there anything else out there that might work?

I am just trying to make a simple video recording app. I have spent days trying to figure this error out and I have had no luck. I am so close to just deleting my whole computer, this error is driving me mad! I followed developer.android.com and YouTube tutorials. I can't see why my code doesn't work as I copied everything they did. [http://pastebin.com/q84v81hG](http://pastebin.com/q84v81hG) I put all the code in a paste bin because the code messes up when I put it here. Thanks for any help! BTW I am aware I haven't added a button that stops recording, I am just trying to get it recording in the first place before I add that.
