If its your first time installing it, I have no idea why its happening. But if you had a older version installed, Its invalid because I lost the original key when I updated java. the solution would be to back up our save located in Phone\Android\data\com.upforkilling.gupp\files\saves . Then uninstall the old one, and restart your phone. You need to restart your phone because that's when Android clears its bin.
