Csipsimple on demand

[GoogleCodeExporter]

Csipimple loads automatically on startup and when I quit still runs in the 
background ...

Most of the time I don't have Wifi, and don't want to drain my battery with an 
app running in the background.

It would be great to have an option which makes Csipsimple runs only when I 
start it and REALLY exit it when I choose exit...

Thanks

This is a common mistake of many users with android system... Using a auto-task 
killer app or an app that monitor other apps is not always a good idea. 
Ok for some apps that's are not well coded, yes it's needed. But if the app 
behaves cleanly, it can be still in the task list but consume absolutely 
nothing.

Android system automatically handle what apps should be open and closed. 
If you configure csipsimple to run only with wifi *for outgoing call* for 
example and you quit it with the quit button :
You'll see in your task manager that csipsimple is still running, but in fact 
it's just a ghost process that does nothing and that is left running by android 
because it doesn't take any resources and it can save time to reload it later.

I advise you to read this article : 
http://blog.radioactiveyak.com/2010/05/when-to-include-exit-button-in-android.ht
ml That explain some things.

Auto-task killers apps should be used with a big knowledge of what they do (and 
sometimes also with the knowledge of how application you kill works). 
I don't know if you already noticed but some android native application such as 
voice recognition, keyboard etc etc restarts automatically. Killing them with a 
task killer (or auto task killer) has the exact opposite effect that the effect 
you want. Loading an app drain the battery. Keeping it freezed in some memory 
place if memory is useless for the system save cpu time.

Once this is said, I admit that there is still work to do in csipsimple to 
fulfill the requirements for an app with a good behavior regarding resource 
management. But... but... the fact it will remains in a task manager is not the 
proof that it behaves as it should. Even better, some apps (such as csipsimple 
that should be aware of network changes), should appear in the task manager.

By the way you can read my code, you'll see that everything is released if not 
needed and that the only thing that remains is a ghost maintained by the 
android system. 
I spent a lot of time on this issue and previously I though just like you that 
it was not normal that the app remains active in the task killer. But after a 
lot of research and tests, and android code reading, I know now that this is 
normal and you should not be afraid of the fact the process appear in your task 
killer.
And last point, this behavior depends on the device : with device with lower 
cpu/ram csipsimple is well properly ended by the android system.

If some task app can convince you, install astro file manager, the embed task 
manager application made the distinction between Applications and Services. 
You'll see that when not needed (and for now ended with the quit button) 
csipsimple will not appear in the Service tab when not needed. Only in the 
application tab and besides no cpu is requested, which mean it's just some data 
that remains in ram and are not freed by the android system. If you open a lot 
of other app so that android will request ram, csipsimple will just disappear 
from the list of applications.

Just a last one... just seen on twitter :

http://www.reddit.com/r/Android/comments/cwhm6/i_stopped_using_a_task_killer_las
t_week_to_see_if/

Even more significant that I though... using a task killer drain the battery by 
25% according to this user.
