We had a bit of a chat about this elsewhere. To recap we saw that fuse was using jdk1.6, but 1.8 was installed so we modifed the `.sdkConfig` file, however this has not solved the issue. I’m going to open an issue for this so we can track in internally. Thanks for posting kevin ---

Hi Kevin A fix is schedule for next release, in the mean time please uninstall old JDK versions, and then run `fuse install android`.
