[操作系统]Android 屏蔽蓝牙连接时的首次配对系统弹窗


连接配对密码已知且固定的蓝牙设备时,明明在代码里就可以完成配对,却依旧被系统弹出配对窗口.

这无疑是令人难受的.

所以,便尝试着去屏蔽掉这个配对窗口.

 

要点:

  • 中断系统发出的蓝牙配对广播
  • 需要用到ClsUtils开源框架
  • 个人测试在Android 4.4上成功拦截,在4.2上不行,也许是高版本把蓝牙配对广播设为了有序广播?

 

code:

public class BluetoothConnectReceiver extends BroadcastReceiver{ private final String TAG = "BluetoothConnectReceiver"; @SuppressLint("NewApi") @Override public void onReceive(Context context, Intent intent) { Log.i(TAG, TAG + " -> BluetoothConnectReceiver start!"); if (intent.getAction().equals("android.bluetooth.device.action.PAIRING_REQUEST")) {  BluetoothDevice btDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);  Log.i(TAG, TAG + " -> ddd");  try  {  Log.i(TAG, TAG + " -> Device Name = " + btDevice.getName());  if ("Device Name X".equals(btDevice.getName()))  {   abortBroadcast();   ClsUtils.setPin(btDevice.getClass(), btDevice, "password");   ClsUtils.createBond(btDevice.getClass(), btDevice);   ClsUtils.cancelPairingUserInput(btDevice.getClass(), btDevice);  }  }  catch (Exception e)  {  e.printStackTrace();  } } }}

通过预设的密码直接静默配对.

 

manifest:

<receiver android:name=".BluetoothConnectReceiver" >  <intent-filter android:priority="1000" >   <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />  </intent-filter></receiver>

接收器的优先级设为最高1000,保证最先被广播通知.
