What happens if you try to run the aapt program from within the App Inventor sources? A while back we updated to the 64 bit versions, so if you’re still on a 32 bit version of Windows you may need to downgrade to an older version that supports 32-bit.
I m using 64bit source and my pc is 64 bit windows 7
Is it I have to install google cloud SDK?
The build server doesn't require the Google Cloud SDK, that's only required for running the front-end service. Like I suggested in my previous post, you should try to run the aapt executable from the command prompt and see what error Windows or aapt provides. That will help us understand how to proceed further with debugging.
HELLO，did you solve your problem?I got the same problem.
