Getting "Caused by: java.lang.VerifyError:"

Question

I created an android application which is used as library in another android application. I used some third party jars in the android app which acts as a library. When I link this library in my android application and run it, I am getting the verify error when it tries to access the class present in the library. May I know what is the issue blocking here for me ? Any help greatly appreciated..

I attached the log here and Parser1 is the class inside the library. I am getting the error in the line when i try to create the object for Parser1 class.

Answer 1

In Eclipse, go to the Project properties -> Java Build Path. Select the Order and Export Tab and check your third party jars.

Answer 2

That can be caused by something in the jar accessing something in Java that's not in the Android SDK. Look in LogCat for the exception and it may tell you what it's missing. If you have the sources for the 3rd party jar, try including them directly into your project; that will help pin down the problem.

You also need to run your jar file through the "dx" tool that comes with the sdk.
