App is much slow

Sir when i make big app (means much data in a screen ) my app is very slow. I mean it give a lot of time to open screen.

During execution or in the builder

You should divide your works in different threads using AsyncTask Component in Appzard. It will make your app fast. Also, make sure to run blocks inside procedure which run in background and do not relate to UI.

Sir i not understand correctly can you help me by give more explanation please ?

But sir everytime when i want to build big app my app screen keep taking much time to open…
So how can i make big app without legging ?

use multiple screen. Not all in one screen.
