<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT"/>
Here is the sample code but keep in mind you will need to customize the StringToJString(‘com.embarcadero.HeaderFooterApplication’) section to match the ID of your own application.

When you application is uninstalled I believe it will remove the shortcuts from the homescreen that point to it so you don’t have to worry about cleaning them out. However, there is also an UNINSTALL_SHORTCUT permission and you can remove shortcuts that your app has created as well.
And finally you can download a full demo application which creates a shortcut.
