Android app lags when using hdpi resources
<p>I have run into a rather strange problem. I am making a game for Android and until now I have been using sprites that are in the baseline (mdpi) density. Basically I would dump all my sprites into the <code>/res/drawable</code> folder; there are no folders for different screen densities yet. I am currently testing my app on a physical device whose screen density is hdpi, so naturally I made a <code>/res/drawable-hdpi</code> folder and I put all the scaled bitmaps in there. However, my app seems to be running really slow; when it tries to draw and animate all the game objects there is a huge lag. This does not happen when I used the contents of the <code>/res/drawable</code> folder.</p>

<p>I have tried to play around with the <code>supports-screens</code> tag in my AndroidManifest.xml file but they didn't really seem to do much. This is what I had:</p>

<pre><code>    &lt;supports-screens android:resizeable="true"
                  android:smallScreens="false"
                  android:normalScreens="true"
                  android:largeScreens="true"
                  android:anyDensity="true"/&gt;
</code></pre>

<p>Surely there is more to using bitmaps for different densities than just simply dumping the scaled versions in their respective folders.</p>
