找到广播接收器动作

Question

我正在开发用于蓝牙连接的android广播接收器

问题在于广播接收器采取了所有措施，但只采取了ACTION_FOUND。

这是意图过滤器

IntentFilter filter1 = new IntentFilter();

filter1.addAction(BluetoothDevice.ACTION_FOUND);
filter1.addAction(BluetoothDevice.ACTION_CLASS_CHANGED);
filter1.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);
filter1.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);

registerReceiver(mBroadcastReceiver1, filter1);

这是广播接收器

private final BroadcastReceiver mBroadcastReceiver1 = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {

    final String action = intent.getAction();
    Log.e(TAG, "onReceive: ACTION____________come in Receiver1");
    if(BluetoothAdapter.ACTION_DISCOVERY_STARTED.equals(intent.getAction())) {
        Log.e("Action?::", action);
    }
    else if(BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(intent.getAction())) {
        Log.e("Action?::", action);
    }
    else if (BluetoothDevice.ACTION_CLASS_CHANGED.equals(intent.getAction())) {
        Log.e("Action?::", action);
    }
    else if (BluetoothDevice.ACTION_FOUND.equals(intent.getAction())) {
        Log.e("Action?::", action);
    }

  }
};

这是日志
