I used es file explorer, but it actually did work, at one point. I was using 0.3 and saw the update button. I pressed it and went to the site. It started downloading so I went back to playing 0.3. It finished downloadING and I went to es file explorer and pressed the 0.4 application and hit install. It installed and when it finished it directed me back to the updated game. This is how I got it to run the first time
