Android: The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files

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 the error will be resolved ..
This somehow cleared up eclipse's cache and rebuilt the project successfully.

3)  Apply following steps:
  • Right click the project in the package explorer.
  • Source > Clean up...
  • Next > Finish
4)  Right Click(Project) -> Properties -> Java Build Path -> Libraries -> Add Library -> Select the Java Library
Click OK and then clean-build (Project -> Clean & Project -> Build All or Ctrl+B) your project. It should be fine.

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'. 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...

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");  }
