Currently you can load up to 4 of your favorite Android applications with the official ARC runtime.
By default the chromeos-apk tool replaces the Vine application and everytime you load a different app it replaces it. However you can load 3 more apps by replacing Evernote and other apps. For each extra app adjust the "key" value in the manifest.json file of that app, then use "Load unpacked extension...".
To load unlimited number of apps you need a custom runtime, see the ARChon runtime guide for details.
