Chromecast is sending disconnect command due to heartbeat timeout, preventing graceful reconnect #640

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Note this is only happening on certain devices:

What steps will reproduce the problem?
1. Open Haystack TV 
2. Cast a video and put the app aside, waiting for the screen to turn off on 
the device.
3. Wait a few minutes while a video or two plays.
4. Open the device , when Haystack TV resumes you will notice that the 
Chromecast disconnects, Haystack TV can not use Chromecast reconnect because it 
got a disconnect command :

D/CastDeviceController( 1101): [controller-0020 API] disconnecting due to 
heartbeat timeout

What is the expected output? What do you see instead?

Ideally the disconnect command is not sent. This way when the app resumes it 
can gracefully reconnect to the Chromecast session (Haystack TV enables 
Chromecast reconnect provided we did not receive a disconnect command).

What version of the product are you using? On what operating system?

This is happening with a Nexus 7 1st gen tablet running version 4.2.2 of 
Android.

Please provide any additional information below.

I'm attaching a log file captured when this issue happened.

Are you using the Cast Companion Library in your app? We highly recommend that 
you use CCL instead of trying to implement your own reconnection logic.

Yes we are using the Cast Companion Library right now and are following it for 
our reconnection logic.

When did you first start seeing this issue?
Do you see it on any other devices (Android/iOS)?
Is more than one video playing on the device before it goes to sleep?
Just to double check, you're using the latest version of CCL, correct?

We are on CCL version 2.1.1. 

We observe the issue also when only one video is playing, it seems to have less 
to do with multiple videos and just how long the screen is off.

In house we are only seeing this on this Android Device running 4.2.2. (we have 
an iOS version but have not seen this problem there). We can't reproduce on 
newer versions of Android.

Are you seeing this issue with the CastVideos app (from GitHub) as well?

We just tested with the latest version of CastVideos / CCL on GitHub and the 
issue is happening there as well. We cast the video and then the screen goes 
off. After about a minute we turn the screen on and the Chromecast has 
disconnected from the tablet, though the video keeps playing on the television.

So when the device wakes up and your wifi reconnects to the access point it was 
previously connected to, is the app still unable to reconnect to the Chromecast?
Also, what version of Google Play Services are you using?

After the screen turns off the wifi never drops on the device. After the user 
turns on the screen the device is no longer casting (i.e. although the TV still 
shows the session the device appears to have lost the connection). 

If the user taps on the chromecast icon then it successfully reconnects to the 
existing chromecast session.

The google play services version on the device is 7.8.99(2134222-030)

Can you run the CastVideos app, try to reproduce the issue there, capture the 
logs, and send them to us?

Hi there, attached here is the log we captured from running CastVideos and 
reproducing the issue.

When you reproduced the error in #11, was that with CCL version 2.4?

Original comment by jonathan...@google.com on 15 Sep 2015 at 5:43

GoogleCodeExporter commented 8 years ago 
Its CCL version 2.1. We can try it on 2.4 and let you know.

Original comment by ish...@gmail.com on 15 Sep 2015 at 5:57

GoogleCodeExporter commented 8 years ago 
Yes, please do.

We re-checked and the CCL version was in fact 2.4 for the log report we sent 
out. The use case is working fine on all other devices except for the Nexus 7 
1st gen tablet.

Please reproduce the issue again and make sure you're capturing the CCL logs. 
You can do  this by setting DEBUG=true in CCL in "LogUtils.java" class.

Were you able to reproduce the issue and get the CCL logs? If so, please 
provide them here.
