When I make the command \"react-native run-android\" then it happened:
FAILURE: Build failed with an exception.
Jcenter does not have Gradle 3.0.1.
It is available in Google's maven repository. here
You should add google() to allprojects in your project level build.gradle
Do this:
In your react native project, Navigate to -> android -> build.gradle.
add google() to allproject repository like this:
This should fix your problem.
Edit 1: replace google() with this
maven {
url "https://maven.google.com/"
}
