Use explicit Intent for binding to service.

        mPhoneState = new HeadsetPhoneState(context, this);

        mAudioState = BluetoothHeadset.STATE_AUDIO_DISCONNECTED;

        mAdapter = BluetoothAdapter.getDefaultAdapter();

        if (!context.bindService(new Intent(IBluetoothHeadsetPhone.class.getName()),

                                 mConnection, 0)) {

        Intent intent = new Intent(IBluetoothHeadsetPhone.class.getName());

        intent.setComponent(intent.resolveSystemService(context.getPackageManager(), 0));

        if (intent.getComponent() == null || !context.bindService(intent, mConnection, 0)) {

            Log.e(TAG, "Could not bind to Bluetooth Headset Phone Service");

        }
