I am using an AsyncTask to fetch the ring tone for a contact when my application starts, it works fine until after my Activity closes a couple of times during the AsyncTask, after this happens the AsyncTask will only ever get to onPreExecute() and never doInBackground, so I can never fetch the ringtone then until either a force stop or d...

Hey guys, I use an AlarmManager to run a Service which tries to download a file from the web. If it fails I'd like to retry that Service in 5 minutes. Inside the Service I run an AsyncTask to run my code. As far as I know the only way I can tell if it failed or not is from the onPostExecute(). What is the best way of implementing a re...

I want to implement a generic, thread save class which takes the RessourceId of an ImageView and the Url (http) where the desired image file is stored.
