- Put .jar file on your SD card
- Make sure Java is installed
- If you're not sure if Java is installed, get a drum and a maraca
- Beat the drum with the maraca while doing a dance to your local sky god
- Mumble, sing, or shout prayers to said sky god
- If you're lucky, you might get the .jar installed but I doubt it since the package installer only recognizes .apk files,
afaik
