error: failed linking references.

Answer 1

resource android:attr/fontVariationSettings not found.
resource android:attr/ttcIndex not found.

Change the compileSdkVersion to:

compileSdkVersion 28

fontVariationSettings andttcIndex were added in api level 28 .

Also you are using

implementation "com.google.firebase:firebase-auth:18.1.0"

Firebase migrated to AndroidX in the latest release. It means that you are using both, support libraries and androidx libraries.

You can:

• migrate to androidx as described below
• downgrade your firebase dependencies (but it is not a real solution because you have to migrate before or after)

You can check theofficial release notes :

Warning: This release is a MAJOR version update and breaking change. The latest update to Google Play services and Firebase includes the following changes:

Migration from Android Support Libraries to Jetpack (AndroidX) Libraries. Libraries will not work unless you make the following changes in your app:

• Upgrade com.android.tools.build:gradle to v3.2.1 or later.
• Upgrade compileSdkVersion to 28 or later.
• Update your app to use Jetpack (AndroidX) ; follow the instructions in Migrating to AndroidX .
