title: Modifying platform/frameworks/base package
body: <p>I'm planning to modify some bits in the platform/frameworks/base project in Android Donut r2. The modifications are very small and goes into java packages <code>android.graphics</code> and <code>android.text</code> (the API isn't affected).</p>
  
  <p>What jar libraries do I have to copy from the recompiled platform? the modifications are small and I don't want to replace the whole system.. I'm trying to replace specific jar libraries.</p>
