There is a flaw in the mechanism used by AudioService to detect the fact that mediaserver process did crash and restart. It relies on polling AudioFlinger service until a successful connection triggers a callback into AudioSystem JNI and then into AudioService. But if another thread in system_server process, not attached to the JNI environment, reconnects before AudioService, the callback is called in a detached context and dropped. The fix consists in attaching the thread executing the callback and detaching it if needed. Bug: 9693068. Change-Id: I184308b12a3f87653bf818abf0159e0e45a66ef0
