Uses unchecked or unsafe operations

[Katekko]

This happens when I build for release!

Just a note, didnt crash my apk

This error crashed my emulator. It works fine when I build the APK though

Adding this line to my build.gradle file fixed the problem:

gradle.projectsEvaluated {
    tasks.withType(JavaCompile) {
        options.compilerArgs << "-Xlint:unchecked"
    }
}
