Answer 1

Maybe the error is related to your SDK version. Please upgrade it.

Answer 2

In your android/build.gradle File

buildscript {
repositories {
    google()
    jcenter()
}
dependencies {
    classpath "com.android.tools.build:gradle:3.5.0"
    ...
}
}

And also add In your android/gradle/wrapper/gradle-wrapper.properties.

Answer 3

It is recommended to shift to connectivity_plus instead of connectivity as it might not be properly supported

Here is the installation guide

If not then please check the issues thread as above, most probably it is an issue with your setup
