Android documentation says that AsyncTask postExecute()
is called on the UI thread. I was under the impression that postExecute()
was called from the Thread where execute()
was called : I have been using an AsyncTask in a background Service with its own thread, and postExecute() was called in the service thread, not the main thread.
However, I recently had an issue with the postExecute() not being called at all, while an exception was thrown : " sending a message to a Handler on a dead thread".
How is it exactly :
- shall AsyncTask be used ONLY from the main thread ?
- if not, in which thread postExecute()
is supposed to be called : always the UI thread, or the execute()
calling thread ?
Thank you
