I CAN HAZ CONJECTURE?
Seriously, conjecture is all I've got!
Behold, a working sample!
http://www.jprl.com/tmp/ScratchStartOnBoot.zip
Behold, `adb logcat` [0]!
You'll have to take my word for it that I don't see any "Process
scratchstartonboot.scratchstartonboot has died" messages. (OK, you could
install the .apk in the above .zip...).
The question is...why does my package work, and yours doesn't?
Logging!
Seriously, that's my conjecture. If I remove the Log.Info() messages, I get
[1], where if you look closely enough you'll see that the
scratchstartonboot.scratchstartonboot process runs, then is sent signal 3
(SIGQUIT), and then later signal 9 (SIGKILL)?
My further conjecture as to why the process is being killed is
http://developer.android.com/reference/android/content/BroadcastReceiver.html:
Once you return from onReceive(), the BroadcastReceiver is no longer active,
and its hosting process is only as important as any other application
components that are running in it. This is especially important because if that
process was only hosting the BroadcastReceiver (a common case for applications
that the user has never or not recently interacted with), then upon returning
from onReceive() the system will consider its process to be empty and
aggressively kill it so that resources are available for other more important
processes.
I'd call SIGKILL "aggressively kill[ing] it."
My backup conjecture (also verified) is that, even without all the extra
logging that [0] has, if I change ReceiveBoot.OnReceive():
-
context.ApplicationContext.StartService(new Intent(context,
typeof(LocationService)));
+ context.StartService(new
Intent(context, typeof(LocationService)));
That is, if I do _not_ use `context.ApplicationContext`, but instead use
`context`, then the StartService() call seems to be effective, and the process
isn't killed.
Thus, I would suggest that you try using `context.StartService()` instead of
`context.ApplicationContext.StartService()` to start your Service. If that
fails, add more logging. :-)
