android - 在服务中实现广播接收器

Question

我想在我的 Android 应用程序的整个运行时检查互联网连接。我尝试使用服务，但似乎不是最佳选择。我有什么可能的方法来在服务中实现广播接收器吗？还是我必须放弃服务并单独使用广播接收器？

Answer 1

我将向您展示如何在服务中创建 SMS 接收器:

public class MyService extends Service {

@Override
public void onCreate() {
    BwlLog.begin(TAG);
    super.onCreate();

    SMSreceiver mSmsReceiver = new SMSreceiver();
    IntentFilter filter = new IntentFilter();
    filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
    filter.addAction(SMS_RECEIVE_ACTION); // SMS
    filter.addAction(WAP_PUSH_RECEIVED_ACTION); // MMS
    this.registerReceiver(mSmsReceiver, filter);

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);
    return START_STICKY;
}

   /**
 * This class used to monitor SMS
 */
class SMSreceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if (TextUtils.equals(intent.getAction(), SMS_RECEIVE_ACTION)) {
             //handle sms receive
        }
    }
}
