title: Different android:minSdkVersion and targetSdkVersion causing performance problems
body: <p>I am currently developing an android app, testing it on my Nexus S. If I am running it, using minSdkVersion="7", targetSdkVersion="7" it performs well, but if I set targetSdkVersion (or both variables) to something higher than 13, the app starts to perform very bad.</p>
  
  <p>After my custom views finished to draw, the GUI of the app hangs (no ANR is shown) for about 5 seconds, then it works perfectly.</p>
  
  <p>Any ideas?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I would like to develop my app on API 16, but being downwards compatible to API level 7, so I thought of testing it on API 16 as well as API 7. But on level 16 it performs poorly.</p>
  
  <p>IMO this does not make sense, because if my phone uses Android 4.1, apps targeting level 16 should perform better than once targeting 7.</p>
  
  <p>What are the main differences between API 13 and 14 when drawing Views?</p>
  
  <p>I am using some custom views, the SherlockActionbar and ViewPager from the support package.</p>
  
  <p>Thanks</p>
