[Learn] : How to setup the private server of App Inventor on QNAP

This article is reproduced from CAVEDU education blog with permission.   App Inventor was originally  a sub-project from Google Lab, initiated by Google engineers and courageous users. It’s a completed  online Android programming environment, which uses the Blocks-based coding programs instead of complex codes. On January 1, 2012, Google Lab transfer this project to MIT Center for Mobile Learning for maintenance, and keep it free and open source.   It’s quite intuitive and convenient to develop a program from web browser via App Inventor. First, users need to design the UI/UX,…
