You can create a subclass of Application and start the loading in its
onCreate() method.
When the second activity is started it can check if the loading is
completed. If it's not completed yet it can register itself as a
listener that will be called by the AsyncTask.
However, as a user I would prefer to have the splash screen and
progress dialog merged into one screen with the logo, a progress
indicator and the text "Loading list. Please wait..."
I agree with this, if they are going to press the button, and STILL have to wait for the data to load, might as well put a progress bar on the splash, so they have something pleasant to look at, remove the button, and automatically take them to the next screen when everything is loaded, so they don't have to press anything.
