Instrumentation run failed due to 'java.lang.IllegalAccessError'

Question

I'm writing tests for Android project right now and just don't understand why is this such a pain! After a whole day of setup I finally get it work, but now, after I have written several test classes Intellij IDEA stands:

Test failed to run to completion. Reason: 'Instrumentation run failed due to 'java.lang.IllegalAccessError''. Check device logcat for details
Test running failed: Instrumentation run failed due to 'java.lang.IllegalAccessError'

The tests I was running just a couple of minutes ago can't be run anymore. Taking into account I rolled back to my latest commit where everything was ideal and I wasn't changing any settings I'm just wondering why.

Here is what logcat is saying:

Although I didn't even touched this class, the CheckPasswordActivity line:130 it refers to is just:

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu_check_password, menu);
        return true;
    }

Answer 1

I have finally found a solution. The problem was with dependencies indeed, it is still unknown why it used to work and then suddenly refused, but here is how the dependencies should look like for your test module:

So all in all you need to make sure all your libraries and project libraries are listed for your test module and marked as "Provided" except Robotium lib, which is "Compile".

Answer 2

In my case, it is due to the duplicate jars being included.

Answer 3

Based on your other question... I think I have somewhat of a similar setup as you... Here is pretty much how my dependencies are set (read sub-items as dependencies)

• ActionBarSherlock
  • android-support-v4
• Android Module
  • ActionBarSherlock
  • android-support-v4
• Unit Test
  • robotium
  • Android module

All the dependencies are all setup as "compile"

I use ActionBarSherlock from the source code and that module has "Is a library project" checked.
