Remember it wont allow spaces there fore i used underscores,now click ok.
MIT App Inventor-
App Inventor for Android is an open-source web application originally provided by Google, and now maintained by the Massachusetts Institute of Technology (MIT).
It allows newcomers to computer programming to create software applications for the Android operating system (OS). It uses a graphical interface, very similar to Scratch and the StarLogo TNG user interface, which allows users to drag-and-drop visual objects to create an application that can run on Android devices. In creating App Inventor, Google drew upon significant prior research in educational computing, as well as work done within Google on online development environments.

The third window Components-it contains all the components added.
The fourth window MEDIA-it is present below components window it is to upload photo,sound.video or any other media.
