Crash during Twilio chat client shutdown on Android 8.0 (API 26, Oreo)

Question

On Android 8.0, I am getting a consistent crash when calling client.shutdown() , with the following error message:

A/libc: invalid pthread_t 0x7dd83384f0 passed to libc
A/libc: Fatal signal 6 (SIGABRT), code -6 in tid 28040 (RxCachedThreadS)

The pthread implementation returns null pre-8.0 but fatally crashes on >=8.0 when the thread is not found, I believe this is related.

Potentially useful lines from ChatClient.setLogLevel :

W/TWC: TNRegNotificationCtxSession:       540533023984 | 10/04/16:57:35.623 | WARNING  | 26     | TNRegNotificationCtxSession | Could not operate with notification context in twilsock. Error 9
E/TWC: TNWebsocket:       540501275888 | 10/04/16:57:35.624 | CRITICAL | 9      | TNWebsocket | Received error while waiting for message: Net Exception

I can provide the full logs if needed. Thanks!

Answer 1

Twilio rep here, (RxCachedThreadS) are you using some RxJava in your app?

In any case, providing logs as per this howto is perhaps the best way forward.

JFYI: SO is probably not the best place for bug reports and crash investigations, so please open a ticket on github here and we'll be able to do it there. Thanks!
