Concern on performance overhead for image scale
<p>My android app will work for both normal and hdpi device. I don't want to create two sets of images assets for normal and hdpi screen. </p>

<p>So, could I just create image assets for hdpi only, and use them for both normal and hdpi device. Of course, the hdpi images will be auto scaled to fit normal screen devices. Is it OK? How much performance overhead will be caused by auto scaling hdpi images to fit normal screens?</p>

<p>Thanks.</p>
