ARChon Custom Runtime Guide

ARChon runtime lets you run unlimited number of Android APKs created with chromeos-apk on Chrome OS and across any desktop platform that supports Chrome.

Warning: The custom runtime will replace the official runtime component. To go back to the official runtime you will need to uninstall the custom one and reinstall the official one.

ARChon source

ARChon source is hosted here: It's on BitBucket because GitHub has a 100mb file limit. Feel free to hack on ARChon and tweak it.

Changing app resolution

Tweak the runtime in 2 places: You need to change the tablet resolution values in these 2 places: and

Find tablet: {"long": 1280, "short": 800}, tweak it, fit your resolution, reload the run time.

Tweak Apps

Add "resize": "scale" to "arc_metadata" in manifest.json.

How to adjust font size

  1. Modify the two files (gen_index.min.js and gen_main.min.js).

  2. Search a.prototype.computeValues_.

  3. Change the value of a.prototype.computeValues_.

  4. Let the value c double. Just like the following codes.

a.prototype.computeValues_ = function (a) {
    var c = 2*window.devicePixelRatio / getCurrentZoom() 

Read the manifest guide for more advanced tweaks.
