java.lang.VerifyError for AIDL Service

Question

I'm working on getting an app communicating with an external service in another application (called CSipSimple). I'm able to bind to the service:

ServiceConnection mConnection = new ServiceConnection(){
    @Override
    public void onServiceConnected(ComponentName comp, IBinder svc){
        ISipService mSvc = ISipService.Stub.asInterface(svc); // Exception here
        ...
    }
    ...
}

Intent i = new Intent("com.csipsimple.service.SipService");
getApplicationContext().bindService(i, mConnection, BIND_IMPORTANT)

The exception is thrown on the indicated line. I've searched around and tried all of the following, to no avail:

• Adding the AIDL files to the source folder of the project
• Adding the other application (CSipSimple) as a required project
• Check off all of the entries in the Order/Export list
• Cleaning and rebuilding both applications

The following errors are generated:

It looks like it can't find some of the required classes/methods, but I've added all of the AIDL files to my project. Any help would be greatly appreciated!

I was able to solve this by making SipHome a library, and including it in my application from the Project Properties -> Android -> Library dialog.
