AAPT: error: resource android:attr/fontVariationSettings not found

Ionic Framework ionic-v3

Hey,

just tried to run a build today and ran into this issue. I initially didn’t do any updates or anything, just tried to run a build.

Failed to execute aapt
com.android.ide.common.process.ProcessException: Failed to execute aapt

I’ve spent the past day looking around for ideas on what I’m supposed to do to fix it. I’ve tried updating cordova, updating some plugins, removing/cleaning the android platform and I can’t seem to figure out what exactly is causing the issue (I’ve been going between this error and a Merge error with appcompat and something called androidX).

From what I can gather fontVariationSettings was introduced in the android v28 API but I’m not too sure what exactly is happening or why this issue is happening now.

I have a feeling my environment in general is a little messed up now from updating/reverting things but this is what I’m at now:

Managed to get it to build:

changes/added/removed the following plugins:

cordova-plugin-androidx (add)
cordova-plugin-androidx-adapter (add)
cordova-plugin-camera (updated)
cordova-plugin-compat (remove)

changed the target in project.properties to:

target=android-28

project.properties by the end:

target=android-28
android.library.reference.1=CordovaLib
android.library.reference.2=app
cordova.system.library.1=androidx.legacy:legacy-support-v4:1.0.0
cordova.system.library.2=androidx.appcompat:appcompat:1.0.0
cordova.system.library.3=com.google.android.gms:play-services-analytics:+
cordova.system.library.4=androidx.legacy:legacy-support-v4:1.0.0

Still have no idea why it even started trying to use androidx. The app was building just fine a few weeks ago and I hadn’t changed anything. Oh well, it’s using it now I guess…
