I compile the jni part of my code, the camera libs ares copied, but the libopencv_java.so is ways missing. I do this copy by hand then everthing works...

my android.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=STATIC
include ../includeOpenCV.mk
include $(OPENCV_MK_PATH)

LOCAL_MODULE    := olah
LOCAL_CFLAGS    := -Werror
LOCAL_SRC_FILES := part_jni.cpp 
LOCAL_C_INCLUDES += $(LOCAL_PATH)/../../../libs/
LOCAL_LDLIBS    += -llog -ldl -lGLESv2

include $(BUILD_SHARED_LIBRARY)

When you use static OpenCV linking via

OPENCV_LIB_TYPE:=STATIC

You don't need libopencv_java.so: the OpenCV code is embedded into your jni library via "*.a" files from the OpenCV SDK (look into OpenCV-2.4.2-android-sdk/sdk/native/libs/armeabi-v7a/ content). This approach increases your APK size (in worst case you'll have to keep 3 copies of OpenCV code for armeabi, armeabi-v7a and x86).
We recommend use of OpenCV Manager instead to share the same OpenCV binaries across all app-s (slides, tutorial).
