Today I show you how to convert your Scratch projects to APK, ANdroid App, using Phosphorus and App Inventor.
If this video gets 15 likes I will share the source file for APp Inventor!
You will need:
Phosphorus:
https://phosphorus.github.io/
MIT App Inventor 2
appinventor.mit.edu
SCratch
https://scratch.mit.edu/

The process is quite simple, you have to go to Phosphorus and paste the address of your project, then just copy the link and go to app Inventor. I show you how to add the webviewer, buttons and I explain you how to add multiple buttons.
Pros:
Multiple Scratch Projects into one APK!
Easy to do!

COns:
Some SCratch projects might run slow
No sounds (I haven't tried many projects)
You have to be ONLINE , no way to play offline :'(

SO hope you like this Scratch - App Inventor tutorial.
Please share it!

What is Scratch?
Scratch is a free visual programming language developed by the MIT (Massachusetts Institute of Technology) Media Lab.[1] Scratch is used by students, scholars, teachers, and parents to easily create animations, games, etc. It provides a stepping stone to the more advanced world of computer programming. It can also be used for a range of educational and entertainment constructionist purposes from math and science projects, including simulations and visualizations of experiments, recording lectures with animated presentations, to social sciences animated stories, and interactive art and music.[2] Viewing the existing projects available on the Scratch website, or modifying and testing any modification without saving requires no online registration.

Scratch allows users to use event-driven programming with multiple active objects called sprites.[1] Sprites can be drawn, as vector or bitmap graphics, from scratch in a simple editor that is part of Scratch, or can be imported from external sources, including webcams.

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.
MIT App Inventor has grabbed the attention of:

Formal and informal educators who have used MIT App Inventor to introduce programming to their Computer Science students, science club members, after-school programs’ attendees, and summer campers. Many educators have also started to use MIT App Inventor to develop apps in support of their own instructional objectives.
Government and civic employees and volunteers who have harnessed the power of MIT App Inventor to develop custom, often hyper-local apps in response to natural disasters and community-based needs.
Designers and product managers who have seen the potential that MIT App Inventor has to support the iterative design process via rapid prototyping, testing and iteration.
Researchers who use MIT App Inventor to create custom apps that can process their data collection and analysis requirements in a wide variety of fields from medical to social.
Hobbyists and Entrepreneurswho want to quickly turn an idea into an app without the cost or learning curve of more traditional app creation processes.
