I want to hide title bar no matter is it in background or foreground. I've just tried this code but had error.Can somebody say what's wrong with my code?

This is error:

    Process: com.example.amadey.myapplication3, PID: 21769
    java.lang.RuntimeException: An error occured while executing doInBackground()

My code:

public class Activity extends Activity {
    @SuppressWarnings("deprecation")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        new AsyncCaller().execute();

   }


    private class AsyncCaller extends AsyncTask<Void, Void, Void> {
        @Override
        protected Void doInBackground(Void... params) {
            Activity.this.requestWindowFeature(Window.FEATURE_NO_TITLE);
            return null;
        }
    }
}

You cannot perform UI action in any thread except in main UI thread.

Activity.this.requestWindowFeature(Window.FEATURE_NO_TITLE); this line has to be in onCreate() method of your Activity class.

Also, you better change the name of your activity.

You can't call requestWindowFeature after you call setContentView. It has to be called before. And it shouldn't be called from an AsyncTask at all.
