There is a trouble somewhere in our program.

There are some tricky trouble like "unresolved include jni.h" wich is a crucial include file or basic instructions like "using namespace std" are consider as error.

Solution

• Do not add native nature to Android project.
• Add a new builder (ndk-build) :
• Right click on the project, Properties, Builders, New, Program.
• Give it a name.
• Location : (NDK_location)/ndk-build
• Working directory : Browse workspace, click on the project, then OK
• In refresh tab, check refresh ressources upon compilation and recursively include sub folders.
• In Build Options tab check specify working set of relevant ressources and select again the project.

Now we just have to click on run as usual then ndk-build is called to generate library.
