Don't record audio if UID is idle - core framework
If a UID is in an idle state we don't allow recording to protect
user's privacy. If the UID is in an idle state we allow recording
but report empty data (all zeros in the byte array) and once
the process goes in an active state we report the real mic data.
This avoids the race between the app being notified aboout its
lifecycle and the audio system being notified about the state
of a UID.
Test: Added - AudioRecordTest#testRecordNoDataForIdleUids
Passing - cts-tradefed run cts-dev -m CtsMediaTestCases
-t android.media.cts.AudioRecordTest
