Lambda expressions crash with IncompatibleClassChangeError in Android when using jack
Google are no longer supporting android-jack.
Jack is no longer supported, and you should first disable Jack to use the Java 8 support built into the default toolchain
Android Studio 3.0 and later supports Lambdas expressions. Configure build.gradle file:
android {...// Configure only for each module that uses Java 8// language features (either in its source code or// through dependencies).compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 }}Note: If Android Studio detects that your project is using Jack, Retrolambda, or DexGuard, the IDE uses Java 8 support provided by those tools instead. However, consider migrating to the default toolchain
