Android蓝牙配对时不弹框

Android蓝牙配对框，根据输出log看到，包名是com.android.settings.bluetooth.BluetoothPairingDialog

是在Android原生Setting里面弹出的

对话框代码路径：packagesappsSettingssrccomandroidsettingsbluetoothBluetoothPairingDialog.java

然后跟一下代码，找到触发这个配对框触发的地方：packagesappsSettingssrccomandroidsettingsbluetoothBluetoothPairingRequest.java

public final class BluetoothPairingRequest extends BroadcastReceiver {

  @Override
  public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    if (!action.equals(BluetoothDevice.ACTION_PAIRING_REQUEST)) {
      return;
    }
    // convert broadcast intent into activity intent (same action string)
    Intent pairingIntent = BluetoothPairingService.getPairingDialogIntent(context, intent);

    PowerManager powerManager =
        (PowerManager)context.getSystemService(Context.POWER_SERVICE);
    BluetoothDevice device =
        intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
		
    String deviceAddress = device != null ? device.getAddress() : null;
    String deviceName = device != null ? device.getName() : null;
    boolean shouldShowDialog = LocalBluetoothPreferences.shouldShowDialogInForeground(
        context, deviceAddress, deviceName);
    if (powerManager.isInteractive() && shouldShowDialog) {
      // Since the screen is on and the BT-related activity is in the foreground,
      // just open the dialog
      context.startActivityAsUser(pairingIntent, UserHandle.CURRENT);
    } else {
      // Put up a notification that leads to the dialog
      intent.setClass(context, BluetoothPairingService.class);
      context.startServiceAsUser(intent, UserHandle.CURRENT);
    }
  }
}

由此想出处理方法：

自己定义一个BroadcastReceiver ，自动确认配对，然后拦截掉广播

java代码：

public final class BluetoothPairingRequestReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (!action.equals(BluetoothDevice.ACTION_PAIRING_REQUEST)) {
            return;
        }
        BluetoothDevice device =
                intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        try {
            device.setPairing/confirm/iation(true);//确认配对
            abortBroadcast();//拦截掉广播
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

AndroidManifest.xml：

	 //这里写成1000，最优先接收到广播
