You can start by creating an activity to replace default home screen as following in your app manifest.xml

<activity android:name="ah.hathi.simplelauncher.HomeActivity" android:label="Simple Launcher Home" android:theme="@android:style/Theme.Wallpaper.NoTitleBar.Fullscreen" android:launchMode="singleTask" android:stateNotNeeded="true" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.HOME" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter>
</activity>

By adding the categories android.intent.category.HOME and android.intent.category.DEFAULT to the intent-filter group, when users click on home button, they will be asked to choose between default launcher or your activity. So you can custom your launcher activity as whatever you want.
