after this i setted Project Properties>C/C++ Build

(uncheck) use default build command
Build command: ndk-build
(uncheck) generate Makefiles automatically

now it has these errors

Description Resource Path Location Type * Android NDK: Aborting. . Stop. OpenCV Sample - face-detection line 155, external location: K:\android-ndk-r10b\build\core\build-local.mk C/C++ Problem

i may have renamed the project, and the eclipse forgot to rename the "Refresh Policy".

Just update "Project properties -> C/C++ Build -> Refresh Policy" manually solved my problem.

but it have previous errors?
