Android I'；我正在创建一个服务来读取SMS消息，但是当我运行它时，我得到了一个错误

我得到的错误是“很遗憾，服务已停止工作”，其中服务是我的应用程序的名称。这个问题与我之前的问题类似，但我现在做的是完全不同的事情——尝试阅读短信

MainActivity.java

public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Button start, stop;

        start = (Button) findViewById(R.id.Button1);
        stop = (Button) findViewById(R.id.Button2);

        start.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View v) {

        Intent service = new Intent(MainActivity.this, MyService.class);

        startService(service);

        }

        });

        stop.setOnClickListener(new View.OnClickListener() {

        @Override

          public void onClick(View v) {

        Intent name = new Intent(MainActivity.this, MyService.class);

        stopService(name);

        }

        });

        }

}

我的服务文件MyService.java：

public class MyService extends Service {

    final static String ACTION = "NotifyServiceAction";
    final static String STOP_SERVICE = "";
    final static int RQS_STOP_SERVICE = 1;
    private SMSreceiver  mSMSreceiver;
    private IntentFilter mIntentFilter;
    SMSreceiver notifyServiceReceiver;

    private static final int MY_NOTIFICATION_ID=1;
    private NotificationManager notificationManager;
    private Notification myNotification;
    private final String myBlog = "http://android-er.blogspot.com/";


    @Override
    public IBinder onBind(Intent arg0) {
            return null;
    }

    @Override
    public void onCreate() {
        notifyServiceReceiver = new SMSreceiver ();
        mSMSreceiver = new SMSreceiver();
        mIntentFilter = new IntentFilter();
        mIntentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
        registerReceiver(mSMSreceiver, mIntentFilter);

        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.i("MyService","Service started");
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(ACTION);
        registerReceiver(notifyServiceReceiver, intentFilter);

        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        Log.i("MyService","Service destroyed");
        this.unregisterReceiver(mSMSreceiver);
        super.onDestroy();

    }

    private class SMSreceiver extends BroadcastReceiver
    {
        private final String TAG = this.getClass().getSimpleName();

        @Override
        public void onReceive(Context context, Intent intent)
        {
            Bundle extras = intent.getExtras();

            String strMessage = "";

            if ( extras != null )
            {
                Object[] smsextras = (Object[]) extras.get( "pdus" );

                for ( int i = 0; i < smsextras.length; i++ )
                {
                    SmsMessage smsmsg = SmsMessage.createFromPdu((byte[])smsextras[i]);

                    String strMsgBody = smsmsg.getMessageBody().toString();
                    String strMsgSrc = smsmsg.getOriginatingAddress();

                    strMessage += "SMS from " + strMsgSrc + " : " + strMsgBody;                    

                    Log.i(TAG, strMessage);
                }

            }

        }

    }

}

更新代码后的新日志猫：

要在清单中使用内部类，需要使用$将其与父类分开

com.example.ParentClass$InnerClass

---

它还需要是公共的和静态的。

您在清单中注册了服务吗？是的，我已经注册了服务。更新了代码并发布了LogCat结果。我应该将接收方清单代码更改为

，对吗？是的，但是SMSReceiver应该是“公共静态类SMSReceiver extends BroadcastReceiver”
