I have an AsyncTask
which creates a Notification
and updates it while the progress.
But when the user exists my aplication while the AsyncTask
is working, i loose the Context
and I can't update anymore.
So would it be a good idea to change the function of the back button to the same function as the home button while the AsyncTask is running? Or what is another way to still have access to a Context
?

I tend to avoid AsyncTasks for reasons like this. I normally use them for things that if either the activity or the task dies nothing is lost. For things that I want to make sure that will finish incase the Activity dies or if there is a problem with the background work you should probably use a Service. The platform has a basic one built in called the IntentService
. This should work well for your situation since the Service will have its own context and can update and track Notifications itself.
Another alternative, which I wouldn't recommend but it is possible, is to have the main Application
keep a reference to itself in a static variable. That'll also provide a Context
that the task can use.
