The app is only good for checking lightly done projects and can't handle a lot of images. Most of the time whenever I use it it doesn't show up the images in the project I have made. It's slow whenever I change screens and sometimes it randomly disconnects, which is quite irritating. It works well with no images in a project. It struggles with 20MB made projects. I suggest you just download your project in an apk and sending it you're phone if the app or emulator doesn't work.

I have been a software engineer for the past 20 years. I developed for many types of devices, including Android. MIT AI2 Companion is just amazing! It speed up the dev process so much! It is pretty stable if you know what you do. I don't often write reviews but after reading some 1 star reviews I had to write one! It seems to me that people howadays expect too much without any knowledge whatsoever. You have here an amazing dev tool and still you complain. Stop developing if you can't handle it.
