1、Unknow Application ABI:
      指定 AndroidManifest.xml 中的 sdk version

2、提示 run-as: Package 'xxxx' has corrupt installation
     chmod 711 /data
     chmod 711 /data/data

3、提示断点不生效
     更新 ndk 重编译试试

]]> OpenCV CMake 编译 静态库 和 自己的工程http://www.cppblog.com/helor/archive/2014/03/29/206392.htmlhelorhelorSat, 29 Mar 2014 04:18:00 GMThttp://www.cppblog.com/helor/archive/2014/03/29/206392.htmlhttp://www.cppblog.com/helor/comments/206392.htmlhttp://www.cppblog.com/helor/archive/2014/03/29/206392.html#Feedback0http://www.cppblog.com/helor/comments/commentRss/206392.htmlhttp://www.cppblog.com/helor/services/trackbacks/206392.html
但是关于静态库和生成自己工程文件，一般的教程费老劲了，这都是对于 CMake 不了解的原因

将 OpenCV 编译成静态库 cmake .. -DBUILD_SHARED_LIBS=NO

编译完成后记得执行 CMakeTargets 下的 install 安装 OpenCV

完后，我们再用 CMake 来建立工程
cmake_minimum_required(VERSION 2.6)
project(Demo)
IF(WIN32)
SET(CMAKE_PREFIX_PATH D:/crossprj/opencv/build/install)
SET(CMAKE_CXX_FLAGS_DEBUG "/MTd /ZI /Od")
SET(CMAKE_CXX_FLAGS_RELEASE "/MT /Zi /O2")
SET(CMAKE_C_FLAGS_DEBUG "/MTd /ZI /Od")
SET(CMAKE_C_FLAGS_RELEASE "/MT /Zi /O2")
ENDIF(WIN32)
FIND_PACKAGE( OpenCV REQUIRED )
ADD_EXECUTABLE( Demo SkinDetect.cpp )
TARGET_LINK_LIBRARIES( Demo ${OpenCV_LIBS} )
include_directories( Demo ${OpenCV_INCLUDE_DIRS} )

不再需要拷贝 动态库，也不需要麻烦的设置工程头文件，库路径等

这个地方可能找不到链接库，
error LNK2019: unresolved external symbol _CLSID_MMDeviceEnumerator
error LNK2019: unresolved external symbol _IID_IMMDeviceEnumerator

解决方法
hr = CoCreateInstance(
           __uuidof(MMDeviceEnumerator), NULL,
           CLSCTX_ALL, __uuidof(IMMDeviceEnumerator),
           (void**)&pEnumerator);

缺少 PKEY_Device_FriendlyName
hr = pProps->GetValue(PKEY_Device_FriendlyName, &varName);

解决方法是 #include <functiondiscoverykeys.h>  // PKEY_Device_FriendlyName
