[android-beginners] Timeout executing service - how to avoid this?
Hi,
When I debug my application, it suddenly disconnects from the DalvikVM
without throwing an exception. Regarding this, the emulator shows an
ANR dialog. It happens some time after I have started a service to do
an operation, by a Broadcast receiver. The operation does take pretty
long time, because it is parsing a xml document. It does not stop
after a special point in my code. I know that a Broadcast receiver
needs to be executed fast, but when I start a service by the
context.startService(Intent) method it shouldn't wait for the
service's execution, should it?
I've attached the log (which do have a line with
"07-18 20:35:24.148: WARN/ActivityManager(583): Timeout executing
service: ServiceRecord{43818238
com.kaloersoftware.flickrwall/.FlickrWallService}"
Can it help if I do the xml parsing in a thread?

All callbacks from Android need to be done quickly. This includes
starting services. Only work done on threads of your own creation can
take longer.

Something in your service (onCreate() or onStart(), most likely) is
taking too long.
> Can it help if I do the xml parsing in a thread?
Yes. Use AsyncTask or something to move the XML parsing off the thread
used for the callback.

Thank you very much. I put the xml parsing into an AsyncTask, and it
works perfectly.
