Kotlin code converts a flaky permissions API that returns 1, "1", "true" or null into a reliable boolean using an asBoolean extension on nullable Any that checks Int, String and null branches and returns false by default. Examples show data classes and Kotlin nullability preventing crashes and making the client resilient. Practical advice emphasizes strict typing, using OpenAPI or protobuf for stable contracts and code generation to avoid ad hoc conversion logic.
