installation fails: Could not find com.android.support:support-annotations:27.1.0.

After I installed react-native-ble-plx and ran “react-native run-android” I get the following error. Do I have to upgrade “react-native” currently (0.52.0)? I tried adding dependency to build.gradle for “com.android.support:support-v4:23.0.1” but without success.

Thanks for any help!

This setup fixed it:

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

Alternative solution: Download the .jar and .pom from https://mvnrepository.com/artifact/com.android.support/support-annotations/27.1.0 and put them in the directory it says it is hunting for.
