I have a service that runs fine, until I close the Activity that called it or destroyed it in this case: Activity_Calls. In the service I call this method:
public void TactivarBroucast(int a,int b) {
int t=b*3600000+a*1000;
Date date = new Date(System.currentTimeMillis());
Calendar c = Calendar.getInstance();
c.setTime(date);
c.set(Calendar.MILLISECOND,t);
date = c.getTime();
Timer time = new Timer();
time.schedule(new Temporisador(), date);
}
Already in the class in charge of the Service I create an object of the class Activity_Calls:
Activity_llamadas activity_llamadas;
in onCreate() and onStartCommand() methods:
public void onCreate(){
activity_llamadas= new Activity_llamadas();
super.onCreate();
}
public int onStartCommand(Intent intent, int flags, int startId) {
Activity_llamadas.getmInstanceActivity().TactivarBroucast(10,0);//valores de a y b. Linea 41 del segundo Logcat
return Service.START_STICKY;
} //linea 43 del primer logcat
The methods onDestroy() and onStart() only I have declared have nothing inside.
I find it funny that I put the classic "The application has stopped" 2 times and I generated two identical Logcat (for me):
First Logcat:

Say again that it works well, with the phone screen off, with the activity in the background, but when closing the app, error. Thanks in advance
