Android Drag, Pinch Scale, and Rotate Objects
<p>Does anyone have a resource or suggestion on how to learn how to do pinch scale, drag/pan, and rotation of objects on Android.  I have completed an app for iOS and all of these features were seamless integrated, but I'm not sure where to start with Android.</p>

<p>The purpose of the app is to simply drag images from a menu onto a "canvas" and rotate/scale those images.</p>

<p>Do I use a surface view and simply drag on ImageViews? Does Android have pre built gestures (like pinch)?  How do I work with the point coordinate system to have objects move where the finger is touching? </p>

<p>Could someone point me in the right direction so I can learn how to do this?</p>
