Activity Problem while home key pressed

I have @ activities... MasterGameActivity and GameActivity ... when i pressed the home key while i ma in Gameactivity, and while come back on game then it goes on MasterGameactivity ... i want that it should be on GameActivity... Ca开发者_JS百科n aynone tell that which could be problem...

Every time home is pressed the application goes to the background. and when u re launches the app it will show the launcher activity cause it is the new instance of your App.
