React-native-onesignal: play-services-basement requested by various other libraries

Description:

I've been trying to run my app for a few hours now, and I'm having the following issue:

> Configure project :react-native-onesignal

WARNING: The specified Android SDK Build Tools version (26.0.2) is ignored, as it is below the minimum supported version (27.0.3) for Android Gradle Plugin 3.1.2.

To suppress this warning, remove "buildToolsVersion '26.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
