Getting WindowManager$BadTokenException : Unable to add window

Question

I have ceated a tabbed application using Tab host. There are 5 tabs and the first tab contains one fragment. In that fragment I am trying to show date/time picker upon clicking a particular view. But the app crashes with following error.

I am using CiTux datetime picker.

I have tried a demo app without using tab host and it works great. But it doesn't work while using tabs in my app. Please help with any solutions..

what is the use of AJApplication and what is your launcher activity ? — Radhey, Nov 24 '15 at 13:24
@Jigs AjApplication is the application class and SplashScreen.java is the launcher activity. — Satyasarathi, Nov 24 '15 at 14:38
Is it throws error in EntryTabActivity class while launching new activity using Intent ? — Radhey, Nov 25 '15 at 05:41
@ Jigs No. It throws in FoodFragment class where we are calling the show() method of dialog. — Satyasarathi, Nov 25 '15 at 19:09
generally "WindowManager$BadTokenException " is arise due to wrong context while displaying any type of dialogs . — Radhey, Nov 26 '15 at 06:32

Finally I got the answer. That is the getFragmentManager(), which we are passing in show() method of dialog. We need to create the getFragmentManager() from the TabHost Activity as the dialog try to get the context from it. So it doesn't found the right context object.

DatePickerDialog.newInstance(
                MainActivity.tabContext,
                dateNow.get(Calendar.YEAR),
                dateNow.get(Calendar.MONTH),
                dateNow.get(Calendar.DAY_OF_MONTH)
        );

        dpd.show(MainActivity.tabContext.getFragmentManager(), "Datepickerdialog");

Declare an static instance of your TabHost activity and get the job done. Happy coding.

public class MainActivity extends TabActivity  implements TimePickerDialog.OnTimeSetListener,DatePickerDialog.OnDateSetListener{
private static final String TAG=MainActivity.class.getSimpleName();
AJApplication application;

TabHost tabHost;
public static MainActivity tabContext;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.i(TAG, "onCreate()");
    setContentView(R.layout.activity_main);
    application=AJApplication.getInstance();
    tabContext=this;
    tabHost=getTabHost();

}
