You can generate chrome packages from either APKs on your phones storage, or from apps installed on your phone (It will pull APK)

Open the App, select an APK or App from list. App Name and package name are both pulled from the APK and put into the manifest.json file. Everything is then zipped together in a ChromeAPK folder on your phones storage.
