带有Android本机活动的OpenCV2.4

我目前面临的问题与前面介绍的问题相同，只是我使用2.4版本而不是2.3.1版本

我已经将原生活动（从NDK样本）转换为C++和修改的ANDROID.MK和Appultual.MK。 我也犯了同样的错误（使用~Mat等一个）

当我读到问题的答案时，我意识到我需要添加

OPENCV\u INSTALL\u模块：=on和OPENCV\u LIB\u TYPE:=STATIC

（这很奇怪，因为我还有一个使用原生OPENCV的项目，不需要这两行代码）

但它仍然不起作用

Android.mk如下所示：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

OPENCV_LIB_TYPE:=STATIC
OPENCV_INSTALL_MODULES:=on

include includeOpenCV.mk

ifeq ("$(wildcard $(OPENCV_MK_PATH))","")
    #try to load OpenCV.mk from default install location
    include $(TOOLCHAIN_PREBUILT_ROOT)/user/share/OpenCV/OpenCV.mk
else
    include $(OPENCV_MK_PATH)
endif

LOCAL_MODULE    := native-activity
LOCAL_SRC_FILES := main.cpp engine.cpp
LOCAL_LDLIBS    := -llog -landroid -lEGL -lGLESv1_CM
LOCAL_STATIC_LIBRARIES += android_native_app_glue


include $(BUILD_SHARED_LIBRARY)

$(call import-module,android/native_app_glue)

我得到以下错误：

有什么我遗漏的吗？

尝试替换

LOCAL_LDLIBS    := -llog -landroid -lEGL -lGLESv1_CM

与

---

我结束了对native plasma项目的尝试（在该项目中，显示是通过在位图中写入来完成的），它工作得很好

也许格尔斯搞乱了OpenCV。我认为这两个项目之间没有任何其他区别

---

在某种程度上，问题解决了。不过，如果有人遇到同样的问题并解决了它，我很想了解是什么导致了它，以及如何解决它。

虽然这是一个老问题，但我遇到了同样的问题，并通过添加

LOCAL_LDLIBS    += -lz # Compression library

---

对于我的Android.mk

来说，通过此更正，我不再有以前的错误，而是：由于APK文件无效，安装失败！请检查logcat输出以了解更多详细信息。发射取消！在日志中：我结束了对本机plasma项目的尝试（在该项目中，显示是通过在位图中写入来完成的），它工作得很好。。。。

LOCAL_LDLIBS    += -lz # Compression library
