When using JNI, how do you know if the package name will appear in the C method name?

For instance, if you have a method named save() in class Canvas in package android.graphics, which is the correct JNI name?

Java_android_graphics_Canvas_save

or

Java_Canvas_save

?

Thanks.

Typical you generate the header file and see the name there.

But the package name is used.

It is documented here:

you run javah and have a look at the C names it generates.
