How to stop calling the onDraw() function on a View?
<p>Im clearing up the bitmaps i load in one activity before i more into the other activity. </p>

<p>eg:</p>

<pre><code>pic1 = null;
System.gc();
nextActivityIntent = new Intent(ThisActivity,NextActivity.class);
ThisActivity.startActivityForResult(nextActivityIntent,123);    
</code></pre>

<p>But the problem is system calls onDraw some times after i call "pic1=null". When it happens the application crashes with pointing a NullPoint Exception.</p>

<p>Cab any one suggest me how to stop calling onDraw() after setting the "pic1=null". Can i use synchornized to make this happen.  </p>
