Where can I get the complete list of JNI function for NDK with Android Studio?

Issue

I follow this guide, Hello-JNI https://codelabs.developers.google.com/codelabs/android-studio-jni

From internet sources, I found that the guide/sample//example/tutorial only provide the following example JNI function which is String :

JNIEXPORT jstring JNICALL
Java_com_example_test_helloandroidjni_MainActivity_getMsgFromJni(JNIEnv *env, jobject instance) {

  return (*env)->NewStringUTF(env, "Hello From Nani 2");//5. change return name
}

Above is the implementation, and its declaration is :

public native String getMsgFromJni();

I found there are another example instead of String but that program is for run in PC, not in Android.

I spent many hours but could not found any JNI function except String. I want JNI function for int, void, etc too.
