Apps Activity keeps reappearing

[Geffa]

Hi

I'm an experienced developer although completely new to mobile development. I am trying to write an app which periodically sends an SMS message.

I do this by with my activity instatiating an AlarmManager when a button is clicked. The AlarmManager starts a service which sends the SMS.

All is fine except that when the SMS is transmitted the activity UI is brought to focus again regardless of what is running. I do not wish this to happen. Ultimately my UI will be a configuration of how the service will behave although I have not looked into the data interface between activity and service yet.

Any help much appreciated.

Thanks
Geoff

Can you show me the code that you are using for the AlarmMaanger Intent?

The code for the button to create the time is

alarm.SetAlarm(getApplicationContext());

The Alarm (based on BroadcastReceiver) is as follows

@Override
public void onReceive(Context context, Intent intent)
{
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
wl.acquire();

Intent myIntent = new Intent(context, MyService.class);
context.startService(myIntent);
wl.release();
}

public void SetAlarm(Context context)
{
//sendCurrentLocation(context);
//locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, Alarm.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 10, pi); // Millisec * Second * Minute
}

The MyService (based on Service) is

@Override
public void onStart(Intent intent, int startId) {
sendMessage();
}

Try putting a finish() on the context that is calling the service like this:

@Override
public void onReceive(Context context, Intent intent)
{
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG");
wl.acquire();

Intent myIntent = new Intent(context, MyService.class);
context.startService(myIntent);
context.finish();
wl.release();
}

Thanks for the advice but it gives a compilation error that

"method finish is undefined for type Context"

Started from scratch using

Android-er: Send SMS in Alarm Service at a pre-defined time

as a starting point.

Works fine now.

Still puzzled as to what was happening though
