When connecting/disconnecting and audio device, AudioService was assuming that the call was always successful through AudioSystem.setDeviceConnectionState(). In the case of the connection of a wired headset (mic + headphones), this also causes A2DP to not be used for media playback. The connection can fail if the audio device being connected is not supported by the platform. But if this failure is not taken into account for DEVICE_OUT_WIRED_HEADSET or HEADPHONES, A2DP would still be avoided even when an A2DP device reconnects at boot. The fix consists in executing the connection logic only when the connection was deemed successful. Nothing is altered on the disconnection code path, or the direct connection of A2DP. The javadoc is updated in AudioSystem to indicate the return codes to take into account in setDeviceConnectionState(). Bug 22511833 Change-Id: I22f0d2c7d4ab4fb9ee1be2f248907f721596a16f
