javah location

[app.dev.s...@gmail.com]

Hey dear community,

I have trouble to use havah. I installed AndroidStudio on my ubuntu machine and now I'm trying to write a native app. (The default native code works)
My problem is, that I can't call havah to create my native header files, so does anybody know where it is installed and if not how can i install it.
Thanks for any advise.

Regards,
Alex


PS: I read the post with the javah tool but it didn't help me

With Android Studio 3.0 (preview) and externalNativeBuild integration, you don't need javah. If I add a new native method to my class, e.g.

    public native void qq(int q);

then I will see it painted in red, and if I hover the mouse above, I get a red lamp. If I click it, I can choose to create the necessary C++ function:

and when I click it, I get 

extern "C"

JNIEXPORT void JNICALL

Java_com_example_egl_MainActivity_qq(JNIEnv *env, jobject instance, jint q) {

    // TODO

}

in my native-lib.cpp file.

Enjoy,

Alex Cohn

My experience with "Create function" in Android Studio is that it create the function in the wrong C++ file. I typically simply cut-n-paste it into the correct C++ file.
