Question

Having referred to --> Javah error while using it in JNI

...and --> android - javah doesn't find my class

...I still can\'t get javah to wor

Answer 1

Got it! It needs the compiled class, not the source. Also, the class folder - ./build/intermediates/classes/debug is hidden from the project in Android Studio.

This is the line that finally worked for me. From my module's root folder (/Users/HKS/Code/MusicPlayer-Android/dspLibrary/):

javah -classpath /Applications/Android\ Studio.app/sdk/platforms/android-16/android.jar:./build/intermediates/classes/debug -jni -d src/main/jni -force com.company.audio.LibDSP

Note the -d flag is the output folder, and -force ensures it overwrites any existing files.
