export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:/home/jackie/software/adt-bundle-linux-x86_64-20130729/sdk/platforms/android-18/android.jar:home/jackie/WorkOpenAnd/OpenCV-2.4.7.1-android-sdk.zip

export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$HOME/bin
export ANDROID_HOME=/home/jackie/software/adt-bundle-linux-x86_64-20130729/sdk
export NDKROOT=/home/jackie/software/android-ndk-r9
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$NDKROOT

其中Java环境变量是自动下载并进行设置的。

今天在运行OpenCV/Samples/face-detection程序时，编译NDK时提示，

Android NDK: WARNING:jni/Android.mk:detection_based_tracker: non-system libraries in linker flags: -lopencv_java
Android NDK: This is likely to result in incorrect builds. Try using LOCAL_STATIC_LIBRARIES
Android NDK: or LOCAL_SHARED_LIBRARIES instead to list the library dependencies of the
Android NDK: current module

然后运行的时候就提示cannot launcher, 大概是说 版本不匹配，后来发现在Application.mk文件中，APP_PLATFORM := android-8，而我当前用的版本是18，将其改为APP_PLATFORM := android-18就可以正常运行了。

开启Android Opencv之旅～～
