Airship Android SDK 15.x to 16.0 Migration Guide

Compile and Target SDK Versions

Urban Airship now requires compileSdk version 31 (Android 12) or higher.

Please update the build.gradle file:

android {
    compileSdkVersion 31

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 31

        // ...
    }
}

Java 8 Source Compatibility

Urban Airship now requires Java 8 language features across all SDK modules.

Please update Android Gradle Plugin to version 3.0.0 or higher and change the source and target compatibility for each module that uses Airship SDKs:

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

Modules using Kotlin will also need to set the target version of the generated JVM bytecode:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach  {
    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_1_8
    }
}
