Two Activities as Launcher. One for smartphone and one for tablet

I want to use two dif开发者_JS百科ferent activities as launcher one for smartphone and other one for tablet. i know that i can put both activities as Launcher in manifest, but how can i invoke them for phone or tablet.

You can use a single activity without layout which will check the android version and start the respective activity each time.

if you use use two different activities as launcher it will put two launcher icon in the device.....you should use different builds for that......
