WARNING: The specified Android SDK Build Tools version (23.0.1) is ignored, as it is below the minimum supported version (27.0.3) for Android Gradle Plugin 3.1.4.
Android SDK Build Tools 27.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '23.0.1'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
Getting multiple warning. Any plan to upgrade this project before end of the year?
