Android(安卓)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.
