Delay after pressing a button

After I press a button, Android parse a JSON file and pick the info it needs. Until yesterday, I was using an external library created by a user and it worked perfectly. But now, I don't want to depend on him, so I've searching info about Google's GSON. I've implemented this library with no problem, but now, after pressing the button that opens a new activity there's a delay.

This delay is due to the connection and parsing that are done before the activity shows.

How can I force the app to wait the Internet connection until de Activity is shown? It's a lil bit uncomfortable because after pressing the button, it seems that the app has frozen, but after all data is loaded, the new activity appears.

Thank you in advance!

Use AsyncTask or Handler for network operations. Do never put "long time" operations into the UI thread
