3 years ago From the stack trace, it appears that the AAudio MMAP server is not responding to a Binder request to open a stream. The service is probably stuck in a deadlock. It is very important that we fix this. Thank you for reporting this.
Has the service gotten stuck like this more than once? Can you reproduce it?
It would be a very big help if you could capture a bugreport the next time it gets stuck. Hopefully very soon after the problem occurs before the logs get flushed. A bugreport file will have tombstones that we can use to identify the stuck service threads.
@myj420 - Please file a new bug here and attach the bugreport:
https://issuetracker.google.com/issues/new?component=898361&template=1458029
Then let me know the bug number. Do not attach a bugreport file to a public GitHub issue.

Android version(s): android 11 Android device(s):Samsung galaxy s10+ SM-G9750 Oboe version:1.5 stable App name used for testing: (Please try to reproduce the issue using the OboeTester or an Oboe sample.)
Short description (Please only report one bug per Issue. Do not combine multiple bugs.) we are using the oboe 1.5-stable on the android 11, and when we open a stream with the API AAudio, the thread is stuck, but it not stuck when we use the API OpenSLES. We tried all samples of oboe, and they are in the same situation. After we reboot the device, it works correctly again. we print the stack information when stuck:
