Android NDK C++ JNI (no implementation found for native…)

Question

I\'m trying to use the NDK with C++ and can\'t seem to get the method naming convention correct. my native method is as follows:

extern \"C\" {
JNIEXPORT voi         


        

Answer 1

I had the same problem, but to me the error was in the file Android.mk. I had it:

LOCAL_SRC_FILES := A.cpp
LOCAL_SRC_FILES := B.cpp 

but should have this:

LOCAL_SRC_FILES := A.cpp
LOCAL_SRC_FILES += B.cpp 

note the detail += instead :=

I hope that helps.
