copy one bitmap into another preserving transparency
<p>I am trying to copy a png to another one</p>

<pre><code>Bitmap overlay = BitmapFactory.decodeResource(mContext.getResources(), R.drawable.logo);
Buffer buf = new Buffer
overlay.copyPixelsToBuffer(buf);
myImage.copyPixelsFromBuffer(buf);
</code></pre>

<p>I am not sure what kind of buffer do I have to use there and also I dont know if this is the correct approach. Also, no offset parameter when copying into the new bitmap?</p>

<p>Thanks and sorry for my noobish questions :S</p>
