JNI编译cximage库（附android.mk和application.mk文件及详细步骤）

我们知道cximage是一个非常强大的C++图片库，其依赖于jasper库，png库，jpeg库还有其他的几种库，因我们项目中只用到了这三个库，所以我只使用jni编译这三种库。
先讲一下jni编译成动态so库的几种方式。
1.使用android studio提供的ndk-build编译的方式。
2.使用linux的交叉编译器gcc编译方式。
3.使用tool-chain工具链进行编译。
4.使用android studio的CMakeLists.txt

本文使用的是ndk-build的方式
Android.mk

通过Application.mk文件可以知道我要生成armeabiCPU架构的so文件
因为cximage依赖于其他三个库，下面附上jasper，png和jpeg的编译方式

1.jasper库的编译，注意jasper库依赖于jpeg库，所以先把jpeg库编译成功

Android.mk

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE := jasper#源文件指向LOCAL_SRC_FILES := $(LOCAL_PATH)/jasper/bmp_cod.c $(LOCAL_PATH)/jasper/bmp_dec.c $(LOCAL_PATH)/jasper/bmp_enc.c $(LOCAL_PATH)/jasper/jas_cm.c $(LOCAL_PATH)/jasper/jas_debug.c $(LOCAL_PATH)/jasper/jas_getopt.c $(LOCAL_PATH)/jasper/jas_icc.c $(LOCAL_PATH)/jasper/jas_iccdata.c $(LOCAL_PATH)/jasper/jas_image.c $(LOCAL_PATH)/jasper/jas_init.c $(LOCAL_PATH)/jasper/jas_malloc.c $(LOCAL_PATH)/jasper/jas_seq.c $(LOCAL_PATH)/jasper/jas_stream.c $(LOCAL_PATH)/jasper/jas_string.c $(LOCAL_PATH)/jasper/jas_tvp.c $(LOCAL_PATH)/jasper/jas_version.c $(LOCAL_PATH)/jasper/jp2_cod.c $(LOCAL_PATH)/jasper/jp2_dec.c $(LOCAL_PATH)/jasper/jp2_enc.c $(LOCAL_PATH)/jasper/jpc_bs.c $(LOCAL_PATH)/jasper/jpc_cs.c $(LOCAL_PATH)/jasper/jpc_dec.c $(LOCAL_PATH)/jasper/jpc_enc.c $(LOCAL_PATH)/jasper/jpc_math.c $(LOCAL_PATH)/jasper/jpc_mct.c $(LOCAL_PATH)/jasper/jpc_mqcod.c $(LOCAL_PATH)/jasper/jpc_mqdec.c $(LOCAL_PATH)/jasper/jpc_mqenc.c $(LOCAL_PATH)/jasper/jpc_qmfb.c $(LOCAL_PATH)/jasper/jpc_t1cod.c $(LOCAL_PATH)/jasper/jpc_t1dec.c $(LOCAL_PATH)/jasper/jpc_t1enc.c $(LOCAL_PATH)/jasper/jpc_t2cod.c $(LOCAL_PATH)/jasper/jpc_t2dec.c $(LOCAL_PATH)/jasper/jpc_t2enc.c $(LOCAL_PATH)/jasper/jpc_tagtree.c $(LOCAL_PATH)/jasper/jpc_tsfb.c $(LOCAL_PATH)/jasper/jpc_util.c $(LOCAL_PATH)/jasper/jpg_dec.c $(LOCAL_PATH)/jasper/jpg_dummy.c $(LOCAL_PATH)/jasper/jpg_enc.c $(LOCAL_PATH)/jasper/jpg_val.c $(LOCAL_PATH)/jasper/mif_cod.c $(LOCAL_PATH)/jasper/pgx_cod.c $(LOCAL_PATH)/jasper/pgx_dec.c $(LOCAL_PATH)/jasper/pgx_enc.c $(LOCAL_PATH)/jasper/pnm_cod.c $(LOCAL_PATH)/jasper/pnm_dec.c $(LOCAL_PATH)/jasper/pnm_enc.c $(LOCAL_PATH)/jasper/ras_cod.c $(LOCAL_PATH)/jasper/ras_dec.c $(LOCAL_PATH)/jasper/ras_enc.c#导出头文件LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)\                           $(LOCAL_PATH)/include/#加入头文件LOCAL_C_INCLUDES := $(LOCAL_PATH)/jasper/.deps $(LOCAL_PATH)/jasper/include $(LOCAL_PATH)/jasper/include/jasper#LOCAL_CFLAGS := -I$(LOCAL_PATH)/libjpegLOCAL_LDFLAGS := -L$(LOCAL_PATH)/jpeg/libs/armeabi -ljpeginclude $(BUILD_SHARED_LIBRARY)

Application.mk

APP_ABI := armeabiAPP_OPIM :=debug#引入Android原生支持库,如stdc++APP_STL := stlport_staticAPP_CPPFLAGS := -fexceptions -frtti #允许异常功能，及运行时类型识别#APP_CPPFLAGS +=-std=c++11 #允许使用c++11的函数等功能APP_CPPFLAGS +=-fpermissive  #此项有效时表示宽松的编译形式，比如没有用到的代码中有错误也可以通过编译；使用GNU STL时不用此项std::string 居然编译不通过！！

2.jpeg库的编译

3.png库的编译
由于该库不是我编译的，同事编译的，直接给出编译好的.so文件

后续补充吧。
