You can fix this issue by adding to android/build.gradle:

 maven {
          url "https://maven.google.com"
        }

Like so:

allprojects {
    repositories {
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
          url "https://maven.google.com"
        }
    }

You also need to be compiling for 26 and have your build tools at 26.0.1:
