android - Calling webservice when uninstalling app -

-

i have app webservice. when uninstall app phone want call webservice before uninstallation completes.how can it?

i have searched couldn't it.

thanks in advance!

in android can't make application aware being uninstalled.. have read; detect if app uninstalled

as problem, keep record of active users in web service. after period of inactivity, assume these applications have been uninstalled.
