Error:com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

Question

This is the output of my Gradle console, I am unable to build my project

D:\\Android Projects\\....\\app\\src\\main\\res\\layout\\topic_view_header.xml
Error         


        

Answer 1

My problem was due to an image file name ending with .9.png. I changed the ending to .png and the problem disappeared. I got the hint from the stack trace in Gradle console: The top message was "Execution failed for task :app:mergeDebugResources" and the bottom message was "com.android.builder.png.AaptProcess$NotifierProcessOutput.out"

I look forward to the day when Gradle outputs more helpful error messages...
