Fragment: App loads with white screen for 3 secs before showing proper UI

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>

Error: Retrieving parent for item: No resource found that matches the given name after upgrading to AppCompat v23

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'.

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...

Android: Check whether activity is in stack or not.

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");  }
