Tap delay and long touch time (solved)

i’m working on simple app that will consume some rest ws.
in the beginning of project, i added two button to catch some choices, but buttons and any touch on the application not perform fast, and touching must be on screen about 1second,
after these, i use fastclick.jar, but even it was a bit fast, so i removed it.
i use a samsung galaxy tab with android version 4 for development.

best regards.

actually, tap and touch are catching, but visual effect not show touch is happen.
thank you.
