Low FPS in Android

I have very low FPS in my game. The game gets the data from the server and displays the response(Text and Images) in a scrollview. I use Enhanced Scrollbar plugin for the scrollview. When I run the game first time on the device, I get around 20-30FPS. But from the second time onwards the FPS drops down to 5-10FPS.

Can anyone please help me resolve the issue?
