W systemie Android, Jak mogę uniknąć stosowania metody onStart w przestarzałej wersji?

Question

Mam problem z ustawieniem metody onStart w mojej aplikacji. To zawsze ma przekreślenia, mówiąc: „Metoda ta została zaniechana na poziomie API 5. Muszę onStart nie onStartCommand.

Jak mogę rozwiązać ten problem?

MyNotificationService.java

import android.app.Service; 
import android.content.Intent; 
import android.os.IBinder; 
import android.widget.Toast; 

public class MyNotificationService extends Service { 

    @Override 
    public IBinder onBind(Intent arg0) { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    @Override 
    public void onCreate() { 
     // TODO Auto-generated method stub 
     super.onCreate(); 
     Toast.makeText(this, "OnCreate()", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    public void onDestroy() { 
     // TODO Auto-generated method stub 
     super.onDestroy(); 
     Toast.makeText(this, "OnDestroy()", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    @Deprecated 
    public void onStart(Intent intent, int startId) { 
     // TODO Auto-generated method stub 
     super.onStart(intent, startId); 
    }

Zastosowanie onStartCommand().

Chcesz dowiedzieć się więcej o tym, jak to zmienić, zapoznaj się z dokumentacją Google, jak poniżej.

// This is the old onStart method that will be called on the pre-2.0 
// platform. On 2.0 or later we override onStartCommand() so this 
// method will not be called. 
@Override 
public void onStart(Intent intent, int startId) { 
    handleStart(intent, startId); 
} 

@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
    handleStart(intent, startId); 
    return START_NOT_STICKY; 
}
