恢復活動后，服務再次開始

Question

我在進行項目時觀察到一個非常奇怪的事情，我認為這是一個重復的問題鏈接，但是我沒有找到合適的解決方案。 我正在使用其中創建了后台服務的android應用程序。 我面臨的問題是當我銷毀啟動服務的活動時。 它再次運行服務（不顯示通知），我不知道為什么。 我不知道哪里出了問題。 任何人都可以通過摘錄來解決問題。 提前致謝。 您的幫助將不勝感激。

積極性：

protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_option_selection);

    cm = new ConnectionManager(getApplicationContext());
    isInternetPresent = cm.isConnected();

    serviceIntent = new Intent(getApplicationContext(),MyService.class);
//      serviceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

//  isMyServiceRunning();
    if(!isMyServiceRunning())
    {
        Toast.makeText(getBaseContext(), "There is no service running, starting service..", Toast.LENGTH_SHORT).show();
        startService(serviceIntent);
    }else
    {
        Toast.makeText(getBaseContext(), "Service is already running", Toast.LENGTH_SHORT).show();          
    }
}

    @Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    isMyServiceRunning();
    if(!isMyServiceRunning())
    {
        Toast.makeText(getBaseContext(), "There is no service running, starting service..",    Toast.LENGTH_SHORT).show();
        startService(serviceIntent);
    }else
    {
        Toast.makeText(getBaseContext(), "Service is already running", Toast.LENGTH_SHORT).show();          
    }
}

private boolean isMyServiceRunning() {
    ActivityManager manager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        String temp = service.service.getClassName();
        if ("com.smartclasss.alerts.MyService".equals(temp)) {
            return true;
        }
    }
    return false;
}

服務：

public class MyService extends Service{
   @Override
public int onStartCommand(Intent intent, int flags, int startId) {

    // TODO Auto-generated method stub
    time = new Timer();
    time.schedule(new TimerTask() {

        @Override
        public void run() {
            // TODO Auto-generated method stub
            DateFormat df = new SimpleDateFormat("dd-MM-yyyy");
            final String currentDate = df.format(Calendar.getInstance().getTime());         
            if(flag == false)
            {
                try {
                    savingDateinPref(currentDate);          
                    new DoInBackground().execute(currentDate);  
                    flag = true;
                } catch (Exception e) {
                    // TODO: handle exception
                    e.printStackTrace();
                }

            }
            String val = prefs.getString("TAG_KEY", "defValue");
            if(!currentDate.equals(val))
            {
            flag = false;
            prefs = getSharedPreferences(prefName, MODE_PRIVATE); 
            SharedPreferences.Editor editor = prefs.edit(); 

            editor.remove("TAG_KEY");
             //---saves the values--- 
             editor.commit(); 

            }
        }
    },0,5000);
return START_STICKY;
}
}

似乎您是在onPause中啟動服務，而從未停止
