Question

我有BroadcastReceiver服务注册行动：

BluetoothDevice.ACTION_ACL_CONNECTED
BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED
BluetoothDevice.ACTION_ACL_DISCONNECTED

在与Galaxy S3和Fly iq280上的其他设备连接/断开连接后，调用onReceived（），但在谷歌Nexus 7上没有。

也许我做错了什么？

我的代码：

private void registerConnectionBroadcast() {
    IntentFilter filter1 = new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED);
    IntentFilter filter2 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);
    IntentFilter filter3 = new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED);
    IntentFilter filter4 = new IntentFilter(BluetoothAdapter.ACTION_STATE_CHANGED);
    registerReceiver(mReceiver, filter1);
    registerReceiver(mReceiver, filter2);
    registerReceiver(mReceiver, filter3);
    registerReceiver(mReceiver, filter4);
}

private BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        String deviceAddress = device != null ? device.getAddress() : "";
        Log.d(TAG, deviceAddress);
        if (!isConnected()) {
            SettingsSupport.setDeviceAddress(deviceAddress, ReceiverService.this);
        }

        String action = intent.getAction();
        if (BluetoothDevice.ACTION_FOUND.equals(action)) {
            Log.d("ConnectionBroadcastReceiver", "Device found");//Device found
        }
        else if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
            Log.d("ConnectionBroadcastReceiver", "Device is now connected");//Device is now connected
        }
        else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
            Log.d("ConnectionBroadcastReceiver", "Done searching");//Done searching
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED.equals(action)) {
            Log.d("ConnectionBroadcastReceiver", "Device is about to disconnect");//Device is about to disconnect
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
            Log.d("ConnectionBroadcastReceiver", "Device has disconnected");//Device has disconnected
        }
        else if (BluetoothAdapter.ACTION_STATE_CHANGED.equals(action)) {
            Log.d(TAG, "Bluetooth state is changed to " + state);
        }
    }
};

就我而言，它是在Nexus 4上调用的，但不是在三星S3上。我不认为它会有任何区别，但您可以尝试在清单xml中注册接收器。

BluetoothDevice BroadcastReceiver onReceived（）未调用
