Android Screencast for displaying device screen on computer

Android screen cast can display my Android device (phone or tablet) on a computer screen . It works on my HTC Legend running Android 2.2 .

The screencast will display the device screen on the computer. For rooted ROM, you can also use the computer keyboard and mouse to control the device.It doesn’t handle device screen rotation at all. So phone will display in portrait mode only and tablet in landscape mode only.

Apart from the above, it is a great tool when doing presentation with Android devices. Plug and USB cable and run the software and your audience will be able to see your device screen. No more messy setup of a separate overhead projection unit. And the display quality is way better.

You can Download the Screen Cast from Here.
