Since upgrading my Android SDK, I get a java.lang.VerifyError crash booting my previously working application.
Looking at the logs, there are a few new issues leading up the crash that were not there previously:
Could not find method android.support.v4.content.LocalBroadcastManager.getInstance, referenced from method com.myapp.android.App.setOAuthLoginState
04-12 19:43:10.249: W/dalvikvm(9508): VFY: unable to resolve static method 251: Landroid/support/v4/content/LocalBroadcastManager;.getInstance (Landroid/content/Context;)Landroid/support/v4/content/LocalBroadcastManager;
04-12 19:43:10.249: D/dalvikvm(9508): VFY: replacing opcode 0x71 at 0x0014
android.support.v4.content.LocalBroadcastManager.getInstance appears to still be in the source code for the Android Compatibilty library. This warning is logged before my App.onCreate() is called BTW.
I have tried using both the older version of android-support-v4.jar that previously worked with my application, and also the new version of android-support-v4.jar included in the latest SDK, but the result is the same in both cases (which seems interesting right?).
Also weird is the stream of warnings like so:
W/dalvikvm(12455): VFY: unable to find class referenced in signature (Ltwitter4j/User;)
The twitter4j library referenced here appears to be included correctly in my project.
I'm still learning Java, so am unsure what might be causing this issue. Any help would be greatly appreciated.

The library has to be placed in /libs folder (note: not /lib)
The library must be placed in the /libs folder, not /lib!
Two possible solutions for this problem
- Move all jar files from lib to libs
If you are using Ant to build with pro-guard then add following in proguard file
-keep class android.support.** { *; } -dontnote android.support.** -dontwarn android.support.**
