Libraries do not get added to APK anymore after upgrade to ADT 22
To quote directly from this source:
“When upgrading, the ‘Order and Export’ of the new ‘Android Private Libraries’ is not always checked. And the android-support-v4.jar is now in this ‘Android Private Libraries’ section.
To fix this, go to ‘Order and Export’ and check ‘Android Private Libraries’. Then refresh/clean/rebuild.
After you done this ‘fix’ for a library project, you may need to just close and re-open any depending project, because they may not see this ‘fix’ immediately.”
