Android developpement application
Bonjour tout le monde,
Je débute tout juste avec le développement sous Android
Et j'ai commencé à develloper une application, mais voilà je suis bloquée sur 3de points le premier et le suivant: Il concerne les services sous Android,
voilà la classe activity et la classe qui étend service:
pourquoi il ne rentre pas dans onCreate(Bundle savedInstanceState) ???
Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44
| package com.exercise.AndroidAlarmService;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class MyAlarmService extends Service {
@Override
public void onCreate() {
// TODO Auto-generated method stub
Toast.makeText(this, "MyAlarmService.onCreate()", Toast.LENGTH_LONG).show();
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(this, "MyAlarmService.onBind()", Toast.LENGTH_LONG).show();
return null;
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Toast.makeText(this, "MyAlarmService.onDestroy()", Toast.LENGTH_LONG).show();
}
@Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
Toast.makeText(this, "MyAlarmService.onStart()", Toast.LENGTH_LONG).show();
}
@Override
public boolean onUnbind(Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(this, "MyAlarmService.onUnbind()", Toast.LENGTH_LONG).show();
return super.onUnbind(intent);
}
