Support React Native 0.56

[mcrowe]

Thanks for this library!

RN 0.56 now uses build tools v26 and this library uses v23. Can you update it so that it will compile properly on 0.56+?

Here is an example of a good way to do this: https://github.com/react-native-community/react-native-svg/blob/master/android/build.gradle

Omg ! I haven't updated this project for so long ! yes definitely I 'll have some time on it this week-end 👍

No problem. Anyone can use this library with RN 0.56+ in the meantime by changing node_modules/react-native-referrer/android/build.gradle to:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.3"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
    }
    lintOptions {
        abortOnError false
    }
}

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.facebook.react:react-native:+'
}
