You don't get the result this way. See this link for an example : https://github.com/levinotik/ReusableAsyncTask/tree/master/src/com/example

Basically, here is what you need to do :

• Define an interface (= a listener) that your activity implements
• Set the listener in the asynctask
• Call yourListener.yourMethod() in the onPostExecute
