AAPT Execution errors are the most difficult to pinpoint. There is no single cause and finding the issue is difficult, even for experienced programmers.

The best general advice without specific information about the code inducing the issue is in @Peter 's post. His link is a large list of discussions where developers had and AAPT issue and mostly solved them. You get to do a lot of reading, and might learn something. :slight_smile:

What can a developer do?

  • Avoid the AAPT issue in the first place. Frequently save copies of your Project as an aia. If you have a recent aia that works, revert to a previous version of your app that works when the AAPT fails. Your issue is something you coded between coding the aia and today's disaster.

  • A very common AAPT issue is incorrectly creating a custom icon for the app. Is this your issue? Did you provide a custom icon? Make a copy of your app; delete the custom icon (which should be an png or jpg image ..) and try again. If you avoid the AAPT, congratulations, you found the gremlin.

  • sometimes, sharing your Block code with the community will give someone with a keen eye the ability to find a coding issue in your code. If you don't share code or the aia; all anyone can do is guess what causes the AAPT and the solution is somewhere in the link Peter provided.


Hello Jen

You might like to go through my checklist:

In particular, the most common AAPT (Android Asset Packaging Tool) errors are:

  1. Images that are not Optimised for Android (including the App Icon, as mentioned by Steve)
  2. Using an out-of-date extension
