+ * This test starts an exclusive stream.
+ * Then a few seconds later it starts a second exclusive stream.
+ * The first stream should get stolen and they should both end up
+ * as SHARED streams.
+ * The test will print PASS or FAIL.
+ *
+ * If you plug in a headset during the test then you can get them to both
+ * open at almost the same time. This can result in a race condition.
+ * Both streams may try to automatically reopen their streams in EXCLUSIVE mode.
+ * The first stream will have its EXCLUSIVE stream stolen by the second stream.
+ * It will usually get disconnected between its Open and Start calls.
+ * This can also occur in normal use. But is unlikely because the window is very narrow.
+ * In this case, where two streams are responding to the same disconnect event,
+ * it will usually happen.
+ *
+ * Because the stream has not started, this condition will not trigger an onError callback.
+ * But the stream will get an error returned from AAudioStream_requestStart().
+ * The test uses this result to trigger a retry in the onError callback.
+ * That is the best practice for any app restarting a stream.
+ *
+ * You should see that both streams are advancing after the disconnect.
+ *
+ * The headset can connect using a 3.5 mm jack, or USB-C or Bluetooth.
+ *
+ * This test can be used with INPUT by using the -i command line option.
+ * Before running the test you will need to enter "adb root" so that
+ * you can have permission to record.
+ * Also the headset needs to have a microphone.
+ * Then the test should behave essentially the same.
