as given. *This may be null *if the service is being restarted after its
process has gone away, and it had previously returned anything
except|START_STICKY_COMPATIBILITY
<http://developer.android.com/reference/android/app/Service.html#START_STICKY_COMPATIBILITY>|.

I believe the above statement is not quite correct about when the intent
may be null, please see this as well:
http://developer.android.com/reference/android/app/Service.html#START_REDELIVER_INTENT
You can try reproducing the issue on your development device by using
the DDMS tab in Eclipse in killing the service's process. When Android
restarts the service a bit later, check the intent.

15.12.2011 14:36, Terry ?????:
Occationally users report a NullPointerException Error at
MyService.onStartCommand() for some of my apps.
I never see this error when I try to debug the apps, and I wonder why
this happens.
I have studied the code both for the methods onStartCommand() and
onCreate() for the services in question, but I seem unable to find the
cause of the problem. I suspect that the actual reason for the crash
lies elsewhere.
Here is the stack trace, which seems to be identical for all crashes
on ALL of the apps in question:
java.lang.RuntimeException: Unable to start service
xxxx.xxxx.xxxx.MyService@405274c8 with null:
java.lang.NullPointerException

Caused by: java.lang.NullPointerException

at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:

As the Google error report system does not include device type or
Android os version, I do not know if this occurs only one some
specific devices or os version.
Has anyone got an idea as to what is happening?
Thank you.
Terry
