My first app Build failed! [RunAapt] ERROR: Error running AAPT

Hi it's my first app and I would like to install it on my phone to try it.

I get all the times this error, i've changed the images to tiny png but the error persists.

App Inventor is unable to compile this project.
The compiler error output was

thank you @Anke Anke!!! great, will look it up, can I ask you only one more thing which I don't get?

I was looking for the files created by the app but with no luck. Can you help me with this?

Which files?
This seems to be a new issue, so you might want to open a new topic for it.
