Support move to SD in Android when the project is 2.1
<p>I have an application, its a 2.1 project. I'd like to add "Move to sd" option to my application. How should I do it? 
I must create a new project for android 2.2? If yes how can I make for keep the whole app maintainable and don't have two sepparated projects?</p>

<p>Thanks in advance</p>
