title: How to implement Drag and Drop in android 2.2?
body: <p>I am trying to develop an android app, where user should be able to drag images from one cell of a grid to another. To implement this I need Drag and Drop API which was introduced in Android 3.0, but my app should run in Android 2.2. So, is there a way to implement this using Touch events? If yes, then please provide me some code snippet or any link which describes it briefly. </p>
