[solved] Aapt.exe finished with non-zero exit value 1

I cannot build an android solution now. Any clue what this is about?!

FAILURE: Build failed with an exception.

I’ve reinstalled node, cordova, ionic@beta. Removed and readded the platform. Running out of ideas!

Was an issue with plugins. Removed a bunch and reinstalled and everything builds again.

In my case the problem was, that there were filenames in my assets folder that had invalid characters.

  • Filenames can’t be too long.

  • äöüß… don’t seem to be allowed

  • Spaces seem to be allowed (!)

Also, after making changes to the filenames in src/assets, search your project for assets folder, and delete all it’s content (except for the main asset folder src/assets), because these are not cleaned when you recompile!!!

After changing these filenames (and deleting the files with invalid names in the other (cached) folders (android,…)), the build worked again!!
