Hi, fairly new to android development here, but familiar with java.
Been trying to understand JNI as it offers extremely fast calculation over standard android/java.
The open source mandelbrot set app (uses JNI):
https://github.com/dbrant/mandelbrot-android
runs fine in android studio, [via simulator or through my pocophone]
When I make a tiny change to the jni/mandelbrot_wrap.c file, by changing
"drawing (%d)" to something different like "draw777ing (%d)", the change doesn't show in the output, it still says drawing (...)
Even when I make a fresh copy of the app, with a new name, and change the code using notepad, and then load it into android studio, it still outputs drawing (...)
I don't know what's going on, is the c++ file already compiled in the project somewhere, so that changes in the app are never reflected?
Please help if you can, thanks very much.
