Question

In my android application i use AsyncTask to download the image from internet.

I pass the url and my AsyncTask does the download. But how do i return the bitmap back to my activity. Currently i pass the callback function to my asynctask constructor and in the OnPostExecute i invoke the callback function. Is this the correct way to do it.

Answer 1

The result you return from doInBackground is passed to onPostExecute so simple return the bitmap from doInBackground method and handle it in onPostExecute.
