My project is going on easily but suddenly what I found below bugs when developing an app. I know it's minor bug but it may be useful to anyone. Here is the error: Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'. Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'. Solution: This happens because after updates your android studio uses API 23 by default. 1) First check that your compile SDK version must match the support library's major version. If you are using version 23 of the support library, you need to compile against version 23 of the Android SDK. Alternatively you can continue compiling against version 22 of the Android SDK by switching to the latest support library v22.   2) Go to your project structure -> Properties -> and change Build tool version to...

If you have "ExpandableListView" and show only one child of expandable Listview at a time, then below is the code for it. expendListView.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() { int previousGroup = -1; @Override public void onGroupExpand(int groupPosition) { if(groupPosition != previousGroup) expendListView.collapseGroup(previousGroup); previousGroup = groupPosition; } }); "groupPosition" will return the open group id. So when I expand the other group then open group will collapse. You can also expand specific item of "ExpandableListView" by applying following code: expendListView.expandGroup(i);

Whe n I am using Youtube API and open the video in my application then it shows me below error in Android L Problem java.lang.IllegalArgumentException: Service Intent must be explicit: Intent { act=com.google.android.youtube.api.service.START } Solution: *  The new android youtube SDK as been released!

Add the content provider to your manifest. <provider  android:name="com.facebook.NativeAppCallContentProvider" android:authorities="com.facebook.app.NativeAppCallContentProvider{Facebook-App-Id}" android:exported="true" /> Make sure exported=true (as above) Example: <provider android:name="com.facebook.NativeAppCallContentProvider" android:authorities="com.facebook.app.NativeAppCallContentProvider123456" android:exported="true" />

Issue: 1) When my application start then white/black screen appears, and then main UI is display.  2) Before my fragment load in activity black/white screen appears for 3/4 seconds and then fragment load. Solution: To fix this nasty problem, update the /res/values/styles.xml to include <item name="android:windowDisablePreview">true</item> or <item name="android:windowBackground">@android:color/black</item> for example : <!-- Application theme. -->  <style name="AppTheme" parent="AppBaseTheme">  <!-- All customizations that are NOT specific to a particular API-level can go here. -->  <item name="android:windowDisablePreview">true</item>  <!-- <item name="android:windowBackground">@android:color/black</item> -->  </style>

Solution There's possibility to check current tasks and their stack using ActivityManager . So, to determine if an activity is the last one: request android.permission.GET_TASKS permissions in the manifest. Use the following code: ActivityManager mngr = (ActivityManager) getSystemService( ACTIVITY_SERVICE );  List<ActivityManager.RunningTaskInfo> taskList = mngr.getRunningTasks(10); if(taskList.get(0).numActivities == 1 && taskList.get(0).topActivity.getClassName().equals(this.getClass().getName())) {             Log.i(TAG, "This is last activity in the stack");  }

Solution Try the following any one solution and problem will go away: 1)  Apply following steps: Close the project and reopen it. Clean the project (It will rebuild the buildpath hence reconfiguring with the JDK libraries) OR Delete and Re-import the project and if necessary do the above steps again. 2)  Apply following steps: Go to properties of project with the build error (right click > Properties) View the "Libraries" tab in the "Build Path" section Find the "JRE System Library" in the list (if this is missing then this error message is not an eclipse bug but a mis-configured project) Remove the "JRE System Library" Hit "Add Library ...", Select "JRE System Library" and add the appropriate JRE for the project (eg. 'Workspace default JRE') Hit "Finish" in the library selection and "OK" in the project properties and then wait for the re-build of the project Hopefully th...

To display the system log inside your application, filtered for your own application-name, you could insert the following as an inner class: private static final String LogCatCommand = "logcat ActivityManager:I *:S" ; private static final String ClearLogCatCommand = "logcat -c" ; private class MonitorLogThread extends Thread{     public MonitorLogThread(){     }     BufferedReader br ;     @Override     public void run() {         try {             Process process;             process = Runtime.getRuntime().exec( ClearLogCatCommand );                 process = Runtime.getRuntime().exec( LogCatCommand );                 br = new BufferedReader ( new InputStreamReader (process.getInputStream()));     ...

If the string should not be translated, you can add the attribute translatable="false" on the element, or you can define all your non-translatable strings in a resource file called donottranslate.xml. Or, you can ignore the issue with a tools:ignore="MissingTranslation" attribute. By default this detector allows regions of a language to just provide a subset of the strings and fall back to the standard language strings. You can require all regions to prov...

1. Downloading Google Play Services Google made new Maps V2 API as a part of Google Play Services SDK. So before we start developing maps we need to download google play services from SDK manger. You can open SDK manager either from Eclipse or from android sdk folder. Open Eclipse ⇒ Windows ⇒ Android SDK Manager and check whether you have already downloaded Google Play Services or not under Extras section. If not select play services and install the package.  2. Importing Google Play Services into Eclipse After downloading play services we need to import it to Eclipse which will be used as a library for our maps project. 1 . In Eclipse goto File ⇒ Import ⇒ Android ⇒ Existing Android Code Into Workspace 2 . Click on Browse and select Google Play Services project from your android sdk folder. You can locate play services library project from android-sdk-windows\extras\google\google_play_services\libproject\google-play-services_lib 3 . Importantly while importin...
