Ionic Framework ionic-v3

I guess there are many topics about it, but all the solution didn’t work.
So, I made the topic one more time for people who still have the problem.

Bug Report

I’m trying to build an android app by ionic cordova build android --release .
However, the next error occurred.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processReleaseResources'.
> Failed to execute aapt

What I tried

cordova plugin add cordova-android-support-gradle-release
=> removed and readded platform
=> still had the same error.
