title: Custom sdk with android studio
body: <p>I have built the sdk from AOSP source tree and directed the sdk path in the Android Studio to the new sdk directory. I have checked android.jar and verified that it contains my added classes, fields, and changes.</p>
  
  <p>But when I try to code in the studio I do not find the added fields in code suggestions. For example I added a filed ActivityName in AccessibilityServiceInfo class. But I do not see that. It still contains the original fields. But if I analyze the android.jar file from platform directory under sdk, i can see it is already there.</p>
  
  <p>What I did wrong?</p>
