Clear Bitmap data and make it null
<p>I am working in an android application and I want to Clear my Bitmap data. The scenario is that I am taking a screen capture of an Widget(Imageview) and I am storing it in a Bitmap. This action comes in a Button click. SO after some time I get a Memory error. So I want to clear the values in the bitmap. So to do that I have done the following code :
The BitMap variable is mCaptureImageBitmap</p>

<pre><code>  public void ButtonClick(View v)
    {
               mCaptureImageBitmap.recycle();   
               mCaptureImageBitmap=null;                        
                View ve = findViewById(R.id.mainscreenGlViewRelativeLayout);
                ve.setDrawingCacheEnabled(true);
                mCaptureImageBitmap = ve.getDrawingCache();
    }
</code></pre>

<p>But I get an error of NullPoint exception. Please help me</p>
