Occasionally ANRs on Huawei devices

See original GitHub issue

Issue description

We experience occasionally ANRs on different Huawai devices when clearing video surface on an simpleExoPlayer instance. We experienced something similar before reported by my colleague in #3724.

Reproduction steps

Although we have similar or same devices to test on we cannot reproduce this issue in our environment.

A full bug report captured from the device

Unfortunatly we only have the obfuscated ANR log available but we could deobfuscate the following ANR report from play console:

We are running 2.11.5 and we ware seeing only a couple of ANRs on those devices the last three months Before it was like 100 cases per day per device type.

Looks promising! Will try updating it as well and report back how things go. Thanks!

Thanks! In this case, I’ll close this issue because there is nothing we can do about it. If anything new comes up, please feel free to reopen (or file a new issue).
