+# Running Robotium tests on AMP requires both an "app" APK and a "test" APK

"Robotium" can be a little confusing as we won't actually run Robotium tests at
all. I know that is what AMP uses but maybe you could make this comment a little
less "implementation specific" to avoid confusion?

The issue with that is that the entire reason for this target _is_
implementation specific - AMP's "robotium" test type _requires_ an app APK and a
test APK.

+# with different package names. Our gtests only use one APK, so we build a
+# dummy APK to upload as the app.
