我們知道cximage是一個非常強大的C++圖片庫，其依賴於jasper庫，png庫，jpeg庫還有其他的幾種庫，因我們項目中只用到了這三個庫，所以我只使用jni編譯這三種庫。
先講一下jni編譯成動態so庫的幾種方式。
1.使用android studio提供的ndk-build編譯的方式。
2.使用linux的交叉編譯器gcc編譯方式。
3.使用tool-chain工具鏈進行編譯。
4.使用android studio的CMakeLists.txt
本文使用的是ndk-build的方式
Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := cximage

LOCAL_LDFLAGS += -L$(LOCAL_PATH)/png/libs/armeabi -lpng -L$(LOCAL_PATH)/jpeg/libs/armeabi -ljpeg

include $(BUILD_SHARED_LIBRARY)
Application.mk
APP_ABI := armeabi
APP_OPIM :=debug
APP_STL := stlport_static
APP_CPPFLAGS := -fexceptions -frtti #允許異常功能，及運行時類型識別
#APP_CPPFLAGS +=-std=c++11 #允許使用c++11的函數等功能
APP_CPPFLAGS +=-fpermissive #此項有效時表示寬鬆的編譯形式，比如沒有用到的代碼中有錯誤也可以通過編譯；使用GNU STL時不用此項std::string 居然編譯不通過！！
通過Application.mk文件可以知道我要生成armeabiCPU架構的so文件
因爲cximage依賴於其他三個庫，下面附上jasper，png和jpeg的編譯方式
1.jasper庫的編譯，注意jasper庫依賴於jpeg庫，所以先把jpeg庫編譯成功
Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := jasper

Application.mk
APP_ABI := armeabi
APP_OPIM :=debug
#引入Android原生支持庫,如stdc++
APP_STL := stlport_static
APP_CPPFLAGS := -fexceptions -frtti #允許異常功能，及運行時類型識別

3.png庫的編譯
由於該庫不是我編譯的，同事編譯的，直接給出編譯好的.so文件
後續補充吧。
