OK, now I'm confused.  This says you are doing integration tests for the plugin.  But you're using the sample app.  If the comment is wrong than it should probably be fixed.  If the comment is right then you probably want to redo this testing in the plugin itself, leveraging the technology (same for both traditional unit testing and integration testing) for all plugins, players and the sdk.  I am starting to think testing of sample apps using integration tests should be a sample app in and of itself extensively documented so that customers get how to use the Android testing technology.  And that we do not want to pollute/confuse our basic sample apps with additional layers of complexity.  fwiw.
