App Inventor for Android

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.^[1]

What is MIT App Inventor?

MIT App Inventor is an innovative beginner's introduction to programming and app creation that transforms the complex language of text-based coding into visual, drag-and-drop building blocks. The simple graphical interface grants even an inexperienced novice the ability to create a basic, fully functional app within an hour or less.

^{See the graphical design of the app here.}

Here is core logic of the app.

^{The first 'for' statement is the one to get 5 quick pick numbers.}

^{The second 'for' statement makes list who has numbers from 1~75.}

^{3rd 'for' statement will remove 70 items from the list randomly.}

^{so we will get 5 jackpot numbers for Mega Million.}

^{The good point of this logic is simplification.}

^{If you pickup random numbers from the 75 list then you need to use double 'for' statement to sort the numbers.}

^{The logic is going to be much more complicated.}

^{Above logic is much simpler because it is already sorted.}
