How to suppress "Cannot resolve corresponding JNI function" in Android Studio?

Question

I am creating a native method in Android Studio which is registered using RegisterNatives in JNI_OnLoad when the library is loaded. The problem is that I want to encrypt the method name and signature strings, but if I do that Android Studio doesn't let me compile the app because of this error: "Cannot resolve corresponding JNI function Java_my_app_Native_initializeApplication." How can I suppress this?

Answer 1

Clicking the quick fix button gave me a pop up to add a @Suppress("KotlinJniMissingFunction") annotation to either the class or the file. You can keep it there or move it to all your methods, eg:

@Suppress("KotlinJniMissingFunction")
external fun initializeApplication()

or

@Suppress("KotlinJniMissingFunction")
class Native : AppCompatActivity() {
...
}

The equivalent annotation for Java is @SuppressWarnings("JavaJniMissingFunction") .
