Running “cordova build android” - AAPT: error: resource android:attr/fontVariationSettings not found. \n android:attr/ttcIndex not found

Question

I could use command ionic cordova build android to build my project to apk file well in March, but after about 4 months doing nothings, it became unbuildable now.

I have researched and followed some, but nothings work at all, include: Running "cordova build android" - unable to find attribute android:fontVariationSettings and android:ttcIndex

$ ionic -v 5.0.3

$ cordova -v 9.0.0 (cordova-lib@9.0.1)

Answer 1

Try to going to the platform/android folder and edited the project.properties file and replaced com.android.support:support-v4:+ with com.android.support:support-v4:27.1.0 .

This is just a quick fix on that issue, you have to find which library do you used throw this error.

Answer 2

Change the compileSdkVersion to:

compileSdkVersion 28

fontVariationSettings andttcIndex were added in api level 28 .
