am 1c7ea21b: Add a missing check for a null pointer when processing an Intent

    // process the intent from receiver

    private void parseIntent(final Intent intent) {

        String action = intent.getStringExtra("action");

        if (action == null) return;             // Nothing to do

        if (VERBOSE) Log.v(TAG, "action: " + action);

        int state = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.ERROR);
