My project consists of one TabView ,in this TabView we have 3 tabs i.e. (HOME, SEARCH, BACK).
There is some problem in back button, in HOME tab we use a TabGroupActivity.
When i press the BACK tab then we can go to last activity, and also set tab at the 0 position means(Home) when we press BACK tab
you can put Backpress keyevent in Tab Activity and then user can go back to Activity
