我正在试听蓝牙连接/断开连接事件,以确定是否连接了蓝牙设备。我试图这样做,以便我的应用程序将运行在较旧的Android版本。如何判断蓝牙设备是否已连接?我的代码不起作用
我注册清单中的接收器,例如:
android:name=".BluetoothReceiver">
在我BluetoothReceiver类我有
public class BluetoothReceiver extends BroadcastReceiver{
public final static String TAG = "BluetoothReciever";
public void onReceive(Context context, Intent intent)
{
Log.d(TAG, "Bluetooth Intent Recieved");
final BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
String action = intent.getAction();
if (BluetoothDevice.ACTION_ACL_CONNECTED.equalsIgnoreCase(action))
{
Log.d(TAG, "Connected to " + device.getName());
}
if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equalsIgnoreCase(action))
{
Log.d(TAG, "Disconnected from " + device.getName());
}
}}
但连接和蓝牙从断开连接时,没有任何反应。我究竟做错了什么?
