Questions:

I updated my Android Studio to 3.0 in Ubuntu. When I loaded a project it fails to build and the same project has no issues when it was built in previous version(v2.3) of Android Studio. And the error says,

Error:found unexpected optical bounds (red pixel) on top border at x=14.

Error:.

Error:java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error

How to&Answers:

After updating to Android Studio 3.0 I was also facing the same issue. I solved the problem by setting android.enableAapt2=false

Improved incremental resource processing using AAPT2, which is enabled by default. If you are experiencing issues while using AAPT2, you can disable it by setting android.enableAapt2=false in your gradle.properties file and restarting the Gradle daemon by running ./gradlew –stop from the command line.

Answer:

Finally I found out the problem. It was due to some 9 patch icons that I used in my project resources. I have made use of some 3rd party tool to draw these icons. Now I replaced those icons with that of the same generated using Android studio(see how) and everything is working for me.

Also if you don’t want to use AAPT2. You can disable by setting android.enableAapt2=false in your gradle.properties file as suggested by @capt.swag
