What is the naming convention of JNI call in android

Question

For example, in android Java code, it calls a native method:

private native final String native_getParameters();

Where/how should I grep where is the C++ method defined native_getParameters();?

Thank you.

Answer 1

The C++ method will also contain your namespace (e.g. com.domain.your) and classname (e.g. YourActivity), it will look something like

JNIEXPORT jstring JNICALL Java_com_domain_your_YourActivity_native_1getParameters(JNIEnv * env, jclass clazz)

Note the C++ _1 equates to the _ in your Java method
