Problems getting Jar file to link correctly. Verify Errors

Question

I've been searching the web for a long time, and it seams that this VerifyError isn't that uncommon and can have multiple reasons for tripping. I have created a project, that I've exported as a jar file. It is built with android 2.2 (API 8). This part works fine. But I have a separate project that when I try to import it, I start having problems.

The only way I've been able to get it to work, is to import the jar into a libs folder I created. It then get's automatically added as an Android Dependency and I can use it fine, however I can't attach my javadoc file to it, and in my build configuration it says I can't modify the dependency. (Can't link to a javadoc).

What I thought I should be able to do is simply add it as an external jar, then link the javadoc and source. If I do this, the code that uses the jar shows no errors, and the javadoc comments work. However I keep getting a VerifyError when I run it. I've attached a stack trace that shows the errors. I'm completely out of ideas, does anyone have any suggestions? Am I building the jar file wrong? Am I importing it wrong?

If anyone can help point me in a constructive direction, it would be really appreciated.

Thanks

Ok, so this was frustrating to solve. The solution took about 20 seconds when I spent over an hour researching the problem.

What I had to do was go to: Properties -> Java Build Path -> Order and Export

But rather than just clicking the external jar, I had to move it up to the top of the list for the build path order.

Credit definitely goes to yorkw for pointing me in the right direction.

I believe that Android jar files are a little different. You could try putting the JAR files into the Android "dx" tool It's in the ~/android-sdk/platform-tools
