Application error even at startup

My Android app got killed in the background even when using the foreground. Here is the manifestation of the hole:

and here is the code for service 

 MLog.w(getClass().getName(), "TritonHK started");

         Notification note=new Notification(R.drawable.icon,
                                             "TritonHK is running",
                                             System.currentTimeMillis());
         Intent i=new Intent(this, BGMessages.class);

         i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                    Intent.FLAG_ACTIVITY_SINGLE_TOP);

         PendingIntent pi=PendingIntent.getActivity(this, 0,
                                                     i, 0);

         note.setLatestEventInfo(this, "TritonHK",
                                 "TritonHK",
                                 pi);
         note.flags|=Notification.FLAG_NO_CLEAR;

         startForeground(1337, note);

and this is how I start mine service

:

Intent i=new Intent(this, MyService.class);

        startService(i);

Here is the logarithm of the moment he was killed:

You have two separate processes. Your actions are performed in one process, and your service is running in another. You told Android that your service is a foreground feature that should prevent Android from killing it. However, your actions are taking place in a different process, and when that process goes into the background, Android will simply kill it.

To fix this, put your service and your actions in the same process. Then Android will not kill the process because the foreground service is running in it. Of course, there is no guarantee that Android will not kill your process anyway (if it needs resources), but the chances are pretty good if your application is not resource intensive that it will stay alive.



To put the service and activities in the same process, remove this line from the description <service>

in the manifest:

    android:process=":my_process"

Unfortunately, there is no way to guarantee that your service won't get killed by android: see http://www.androidguys.com/2009/09/09/diamonds-are-forever-services-are-not/

Keeping a service indefinitely is also not such a good idea: http://www.androidguys.com/2010/03/29/code-pollution-background-control/



You can use some methods to increase the priority of a service, but at one point this service will be killed.
