Android 屏蔽藍芽串連時的首次配對系統彈窗

標籤：

串連配對密碼已知且固定的藍牙裝置時,明明在代碼裡就可以完成配對,卻依舊被系統彈出配對視窗.

這無疑是令人難受的.

所以,便嘗試著去屏蔽掉這個配對視窗.

 

要點:

• 中斷系統發出的藍芽配對廣播
• 需要用到ClsUtils開源架構
• 個人測試在Android 4.4上成功攔截,在4.2上不行,也許是高版本把藍芽配對廣播設為了有序廣播?

 

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();   }  } }}

通過預設的密碼直接靜默配對.

 

manifest:

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

接收器的優先順序設為最高1000,保證最先被廣播通知.
