Live streams ended externally freeze the client Android application with an ANR #12

Closed stephen-mojo closed 6 months ago

stephen-mojo commented 1 year ago

---------------------------------------------------------------------------------------------- Issue: ---------------------------------------------------------------------------------------------- The demo application becomes unresponsive and freezes with an ANR if a live stream session is ended externally.

---------------------------------------------------------------------------------------------- IVS Version ---------------------------------------------------------------------------------------------- 1.11.0

---------------------------------------------------------------------------------------------- Repro Steps - Case #1 - Stream key reset on IVS web dashboard: ----------------------------------------------------------------------------------------------

  1. Start a live stream broadcast from the IVS sample app (this repo)
  2. On the IVS web dashboard, locate the live channel
  3. Scroll down to "Stream configuration" section
  4. Click "Reset stream key"
  5. Check "Also stop any current live stream for this channel"
  6. Click "Reset stream key". This will end the stream.
  7. Wait for the client app to display an error saying "ERROR Broadcast failed"
  8. Navigate to Settings screen
  9. Press the X close button

---------------------------------------------------------------------------------------------- Repro Steps - Case #2 - Stream ended externally due to max bit rate being exceeded: ----------------------------------------------------------------------------------------------

  1. Start a live stream broadcast with a video bitrate configuration that exceeds the allowed limits of a Basic channel
  2. Stream to a Basic channel for 10 seconds
  3. Wait for the app to display an error saying "ERROR Broadcast failed" (This is due to exceeding bit rate limits)
  4. Navigate to Settings screen
  5. Press the X close button

---------------------------------------------------------------------------------------------- Expected Results for Both Cases: ---------------------------------------------------------------------------------------------- The settings screen is closed. The user returns to the broadcast screen.

---------------------------------------------------------------------------------------------- Actual Results: ---------------------------------------------------------------------------------------------- Pressing the close button on the settings screen freezes the application and results in an ANR. Before the ANR occurs, the BroadcastSession.Listener.onError() method is triggered with:

D Amazon_IVS_Broadcast: #onError: Broadcast error: Error is: Attempted to recv after receiving shutdown from peer; code=0; uid=405; source=net W Error is: Attempted to recv after receiving shutdown from peer; code=0; uid=405; source=net E ERROR: [src=net] [type=107 code=0 uid=405] Attempted to recv after receiving shutdown from peer D Amazon_IVS_Broadcast: #onStateChanged: Broadcast state changed: ERROR

And the reason for the ANR is:

E ANR in com.amazon.ivs.broadcast (com.amazon.ivs.broadcast/.ui.activities.MainActivity) PID: 30639 Reason: Input dispatching timed out (950ed15 com.amazon.ivs.broadcast/com.amazon.ivs.broadcast.ui.activities.MainActivity (server) is not responding. Waited 5003ms for MotionEvent) Parent: com.amazon.ivs.broadcast/.ui.activities.MainActivity

---------------------------------------------------------------------------------------------- Notes: ---------------------------------------------------------------------------------------------- It happens on multiple devices including a Pixel 6a and a Samsung Galaxy S22 Ultra.

I was able to reproduce this issue in both of the official IVS sample applications (IVS Demo Repository #1 & IVS Demo Repository #2).

This issue also occurs in my own application that uses the IVS SDK.

Even after the stream has ended due to the error, it looks like there are BroadcastSession.Listener.onAudioStats() calls as if the stream is still alive and sticking around. Is there some sort of cleanup that needs to be done in the BroadcastSession.Listener.onError() method to stop the app from freezing up?

Thank you for reporting your issue and providing comprehensive details. We'll investigate on our end.

mboulin commented 1 year ago

After investigating, the error is likely coming form the SDK itself. This will be addressed in the next SDK release. For the time being, and if you are able to, you could switch to an earlier version of the SDK, until a new version is made available.

Thank you for your quick response!

Do you have a recommendation on how far back to downgrade to? I have seen this issue on v1.10.0 and v1.11.0.

mboulin commented 1 year ago

@stephen-mojo we've not seen the same error behavior with this demo when using 1.10.0, 1.90, and 1.8.0.

stephen-mojo commented 1 year ago

I am able to reproduce the issue in the IVS sample application using 1.10.0. I have a parallel ticket open with AWS support where I have provided logcat logs as well as screen recordings of the issue. If these would be helpful for you, let me know how I can send the data over to you.

I am also able to reproduce this issue in our own application when trying 1.9.0 as well as 1.8.0.

Closing for now as you are already engaged with AWS support.
