What is quick way to check if ImageView has bitmap assigned?
<p>I need to quickly and safely check if an android.widget.ImageView currently has a Bitmap of non zero value attached.  What is a quick way to do this.  </p>

<p>Update my image view is set initially drawable set to "logo.png" so if I know that it is currently set to logo.png than I know that the bitmap has not yet been set.  So how can I check if background drawable is currently logo.png</p>

<p>Thanks</p>
