Whenever I try to use the AppStudio cloud service to build an Android app, the build fails. I've tried with both the Quick Report template and the Map Viewer template. I am able to successfully build a Windows app in beta 3, and I was able to successfully build an Android app in beta 2. I am using the new, updated templates. There are no details given when the build fails; its just says, "Android Failed".
Does anyone have any ideas what may be wrong?
