You will need to include repositories used in the librelay library in order to build

repositories {
        maven {
            url "https://maven.google.com"
        }
        maven {
            url "https://raw.github.com/whispersystems/maven/master/preferencefragment/releases/"
        }
        maven {
            url "https://raw.github.com/whispersystems/maven/master/smil/releases/"
        }
        maven {
            url "https://raw.github.com/whispersystems/maven/master/shortcutbadger/releases/"
        }
        maven { // textdrawable
            url 'https://dl.bintray.com/amulyakhare/maven'
        }
        maven {
            url 'https://jitpack.io'
        }
}

Add the library dependency into your application's build.gradle file.

dependencies {
   ...
   implementation 'com.github.ForstaLabs:librelay-android:v1.0.6'
   ...
}

Current beta release also requires the following changes to your application's build.gradle

android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    ...

And add this dependency to build.gradle

dependencies {
    ...
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    ...
}

Finally, your projects ApplicationContext will need to extend from io.forsta.librelay.ApplicattionContext.java

public class ApplicationContext extends io.forsta.librelay.ApplicationContext {}
