Answer 1

This has something to do with versions only.
Try with the changes mentioned below and this might help.
gradle-wrapper.properties -
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
android/build.gradle -
buildscript {
repositories {
...
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
