The TileView widget is a subclass of
ViewGroup that provides a mechanism to asynchronously display tile-based images, with additional functionality for 2D dragging, flinging, pinch or double-tap to zoom, adding overlaying Views (markers), built-in Hot Spot support, dynamic path drawing, multiple levels of detail, and support for any relative positioning or coordinate system.
This light-weight library provides images with letter/text like the Gmail app. It extends the Drawable class thus can be used with existing/custom/network ImageView classes. Also included is a fluent interface for creating drawables and a customizable ColorGenerator.
json2view is a simple library that can convert a compatible JSON file to an Android view so you can load dynamically the view in your Android app without the need to update the APK.
This removes the hassle of updating, re-compiling and uploading the APK to Google Play every time you want to make small or big changes in the UI.
