Error message that I can't solve

Question

I'm getting this error message: requestFeature() must be called before adding content. I have read other questions about this error message here at stackowerflow, and if I understand it correct, it's all about don't call setContentView() before requestFeature(). But isn't this what I have done in my onCreate method? Or could the error have to do with something else? I'm confused and would preciate some help to solve this error! Thanks!

 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 //setContentView(R.layout.activity_main);
 // Set screen to landscape
 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
 // Remove title from screen
 requestWindowFeature(Window.FEATURE_NO_TITLE);
 // Set screen to full screen
 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
 // Create a new object of GameLoop and pass this context
 gameLoop = new GameLoop(this);
 gameLoop.setOnTouchListener(this);
 setContentView(gameLoop);
}

• Simon: Do you have any decorations in the manifest Activity declaration?
• 3D-kreativ: No, I havn't done anything with the manifest file! What else could be wrong?
• thepoosh: what is happening in the GameLoop class at line 78?

Answer 1

You must set the orientation after requesting window feature. your statements must be in the below order

protected void onCreate(Bundle savedInstanceState)
{
 super.onCreate(savedInstanceState);
 // Remove title from screen
 requestWindowFeature(Window.FEATURE_NO_TITLE);
 // Set screen to full screen
 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
 // Set screen to landscape
 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
 // Create a new object of GameLoop and pass this context
 gameLoop = new GameLoop(this);
 gameLoop.setOnTouchListener(this);
 setContentView(gameLoop);
}

• 3D-kreativ: Thanks, but this isn't helping anything :( I have done an application with this order that I have in my code before and that worked fine. So what could the the problem be? I can't continue with my works, it's so irritating
• Sankar V: could you please update your question with complete logcat stacktrace?
• 3D-kreativ: Sorry, but now it seems like there is some other problem! Perhaps my first problem is solved, but my app still close!
• Sankar V: you have nullpointerexception at line 78 in GameLoop.java. Check for any objects for null vales. If u can't solve it, open a new question because your original question has been salved

Answer 2

try for this:

protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
 super.onCreate(savedInstanceState);
 //setContentView(R.layout.activity_main);
 // Set screen to landscape
 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
 // Remove title from screen
 // Set screen to full screen
 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
 // Create a new object of GameLoop and pass this context
 gameLoop = new GameLoop(this);
 gameLoop.setOnTouchListener(this);
 setContentView(gameLoop);
}

• 3D-kreativ: No it isn't. Perhaps is some other problems
