I have had this dilemma for a while now "Android or JavaFX" for creating UI (user interface) applications. If I create Android, then great, but that limits me to phones/tablets, what about computers?
Emulator with it's heavy footprint is not really a solution, unless you are actively developing, so I was looking for easier way to run my apps at any time.
I have come across this ARChon solution when it first came out and decided to give it a go.
First I downloaded their extension and the demo game (2048), copied it to a ARChon folder in my Applications and unzipped both:
in Chrome browser I went to Chrome > Preferences > Extensions
and installed both and run (Launch on the game) it successfully without a problem.
Then I DUPLICATED to the folder of the GAME and replaced their APK with mine, I adjusted the manifest.json with some OBVIOUS changes, and added this folder to Chrome Extensions again, I was able to run it without any problems.
