The changes required are: - Change all usages of when(mCm.method()).thenReturn(...) to doReturn(...).when(mCm).method() because spies must use the latter syntax. - In setDataSaverEnabled, set the mocked return value before sending the broadcast. Otherwise, the first time the method is called, the spy will attempt to send the broadcast, and will crash because it does not have permission to do so. This does not do anything useful yet, but it will be used in future CLs. Bug: 173068192 Test: atest TetheringTests Change-Id: I968bfa76ead25b2d45ed1c0e8ede32df81401579
