When switching away from a Bluetooth headset to the speaker (for example), then switching back to the Bluetooth headset, a few seconds later the audio will be switched back to the "earpiece".
After debugging this, I found that this happens because there are multiple EnableBluetoothScoJob runnables running, with one of them timing out, therefore causing the AudioActivationError state to be set and causing the behaviour of the connection having errored, although this isn't the case and audio is still heard through the BT headset.
This fixes the problem by ensuring that when we start a new EnableBluetoothScoJob, we cancel the existing runnable first (if it exists).
Breakdown
Added call to Handler::removeCallbacks within the BluetoothScoJob::executeBluetoothScoJob ensuring only one runnable is running.
Validation
Tested on a minimal sample app, switching between audio devices in a call, including powering off/on my BT headset at intervals. Working exactly as intended now.
