[sunilpasupuleti]

Its showing https insecure;
Please allow allowInsecureProtocol = true in build.gradle
and also modify the line compile word with implementation

Here is the fixed build.gradle file

buildscript {
repositories {
jcenter { url "http://jcenter.bintray.com/"; allowInsecureProtocol = true }
maven {url "http://repo.spring.io/plugins-release/"; allowInsecureProtocol = true}
mavenCentral()
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'
}
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.1.4'
}

}

apply plugin: 'com.android.library'

android {
compileSdkVersion 27
buildToolsVersion "27.0.3"

defaultConfig {
    minSdkVersion 16
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
}
lintOptions {
    abortOnError false
}
sourceSets {
    main {
        aidl.srcDirs = ['src/main/java']
    }
}

}

repositories {
jcenter { url "http://jcenter.bintray.com/"; allowInsecureProtocol = true }
maven {url "http://repo.spring.io/plugins-release/"; allowInsecureProtocol = true}
mavenCentral()
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'
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.facebook.react:react-native:+' // From node_modules
implementation group: 'com.android.support', name: 'support-v4', version: '27.0.0'
