Unsatisfiedlinkerror: Native Method Not Found - Android

I am developing an android app using C++ code. Trying to use JNI but failed. The code in myFirstApp.cpp JNIEXPORT jint JNICALL Java_com_example_myfirstapp_CreateApp_findMarkersNati

Solution 1:

Your definitions seem correct. According to several similar posts, it may be because of C / C++ name mangling. Try surrounding your methods, around where this API is defined with

extern "C" { }

for example:

extern "C" {
JNIEXPORT jint JNICALL Java_com_example_myfirstapp_CreateApp_findMarkersNative(JNIEnv* env, jobject, jlong addrRgba) 
{
... function code ...
}
}
