Android activity takes 3 seconds to display

Question

When I click on the start button it takes around 3 seconds to display the next UI.

I tested without the Threads of the second activity but result is same. It takes 3seconds and 552 ms to display. The second activity contains 7 TextChangeListners for 7 EditText fields.

This is an Android tablet application mainly for a Galaxy Tab 10.1. I am using Android 3.2 to build this app.

Answer 1

I found the reason for the low performance. Its because the emulator. When I check with real device it works fine.
