Force Close because of onStop()
<p>I finally got everything in my app done, but now whenever I exit it with anything except the Home button, it flashes a force close screen, and then it goes away. I know its not that big of a deal, but I really want that to stop happening, I finally got a logcat on it and it said there was no super.onStop(), so I added that, then it force closed again giving me a nullPointer, </p>

<p>I am closing the application by using moveTaskToBack(true), and any time I use it that is what it does, gives me a nullpointer in my onDraw method. I'm not sure what other info is needed, so let me know, thanks in advance for any help</p>

<pre><code>public void onDraw(Canvas canvas){
        if(checkState == -9){
            canvas.drawColor(Color.BLACK);
            canvas.drawBitmap(bG, 0, 0, paint);
            canvas.drawBitmap(title, display.getWidth()/2 - title.getWidth()/2, 10, paint);
            canvas.drawBitmap(start, display.getWidth()/2 - start.getWidth()/2, 40 + title.getHeight(), paint);
            canvas.drawBitmap(instructions, display.getWidth()/2 - instructions.getWidth()/2, 80 + title.getHeight() + start.getHeight(), paint);
            canvas.drawBitmap(exit, display.getWidth()/2 - exit.getWidth()/2, 120 + title.getHeight() + start.getHeight() + exit.getHeight(), paint);
            canvas.drawBitmap(highScore, 0, display.getHeight() - highScore.getHeight(), paint);
            String high = highLevel + "";
            for(int i = 0; i &lt; high.length(); i++){
                levelOnMenu = high.charAt(i) + "";
                levelPiece = Integer.parseInt(levelOnMenu);
                int placeX = highScore.getWidth() + levelNumber.getWidth()/2 ;
                if(high.length() == 1){

                }
                else if(high.length() == 2){
                    if(i == 0){

                    }
                    else{
                        placeX = placeX + levelNumber.getWidth();
                    }
                }

<p>it is telling me that the first part of the onDraw is null, the drawColor...which doesn't make a lot of sense to me</p>

<p>Here is where I use moveTaskToBack()</p>

<pre><code>if(checkState == -11){
            if(event.getAction() == MotionEvent.ACTION_UP){
                if(x &gt;= display.getWidth()/2 - pauseMenu.getWidth()/2 &amp;&amp; x &lt;= display.getWidth()/2 + pauseMenu.getWidth()/2 &amp;&amp; y &gt;=  display.getHeight()/2 - pauseMenu.getHeight()/2 &amp;&amp; y &lt;=  display.getHeight()/2 - pauseMenu.getHeight()/2 + pauseMenu.getHeight()/3){
                    checkState = previousState;
                }
                if(x &gt;= display.getWidth()/2 - pauseMenu.getWidth()/2 &amp;&amp; x &lt;= display.getWidth()/2 + pauseMenu.getWidth()/2 &amp;&amp; y &gt;=  display.getHeight()/2 - pauseMenu.getHeight()/2 + pauseMenu.getHeight()/3 &amp;&amp; y &lt;=  display.getHeight()/2 - pauseMenu.getHeight()/2 + 2*(pauseMenu.getHeight()/3)){
                    if(sound){
                        sound = false;
                    }
                    else{
                        sound = true;
                    }
                }
                if(x &gt;= display.getWidth()/2 - pauseMenu.getWidth()/2 &amp;&amp; x &lt;= display.getWidth()/2 + pauseMenu.getWidth()/2 &amp;&amp; y &gt;=  display.getHeight()/2 - pauseMenu.getHeight()/2 + 2*(pauseMenu.getHeight()/3) &amp;&amp; y &lt;=  display.getHeight()/2 - pauseMenu.getHeight()/2 + pauseMenu.getHeight()){

                    moveTaskToBack(true);
                }

            }
        }
