我得到的错误是“不幸的是，服务已停止工作”，其中service是我的应用程序的名称。问题与我以前的问题类似，但在这里我正在做一些完全不同的事情 - 尝试阅读SMS消息。我正在创建一个服务来读取SMS消息，但是当我运行它时出现错误
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);
}
}
}
}
}
服务的manifest.xml：
