Android : How do i return my control from an aar application

I have a android-maven "test" project which has a .aar file as a dependency. 
From the test project i am able to call an activity in the aar file. 
Now after my processing i want to cal an activity in my test project using intents.  

The following does not work...
Intent intent = new Intent(getApplicationContext(),cropTestACtivity.class);
startActivity(intent);

 Should we use Class.forName method. Something like this
      Intent intent = new Intent(getApplicationContext(),
      Class.forName("com.project.crop.croptest.CropTestActivity"));
      startActivity(intent);


My test project is in "com.project.crop.cropTesActivity" package.
My activity in aar has the following path ...         (com.sumeru.croptest/com.sumeru.crop.activity.DisplayCroppedImageActivity)

from here i need to call com.project.crop.croptest.CropTestActivity"
