invalid opcode ba - invokedynamic requires

This library internally uses lambdas and thus required Java8 as target. This is natively supported since Android Studio 3.0+.

Add these line in your modules build.gradle file to get support for Java8 features:

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }

If you are using Kotlin you may also have to add:

    kotlinOptions {
        jvmTarget = '1.8'
    }

If you get an error like :app:transformClassesWithDesugarForDebug, you may have to enable desugaring in your 'gradle.properties' file

android.enableD8.desugaring = true
