@hgy29 has made the patches now, they fix a few things and also bring in some improvements.
Fixed: Centered splash images, app name wasn't exported properly, mac could create apk
Improved: now paths to jre and sdk are optional, keep them blank for 'auto' mode - you need Android Studio installed.
If you are on Windows, then get the first file and copy the contents over the contents of the templates folder, then get the 2nd file and replace the old files with the ones that it contains.
If you are on OSX, then get the first file, go to you Applications folder and right-click the Gideros Studio app, show the contents, in there you will find a Templates folder, copy over the files with the files in the file! Then do the same with the 3rd file above.
Don't forget that these are replacement files for some of those you have already - you should not delete anything, just overwrite what needs to be replaced.
