使用zinnia制作android手写输入功能(上)-------------------编译zinnia
环境:64bit win7+eclipse+cygwin+ndk_r8+zinnia0.06
到zinnia官网下载source以及zinnia-tomoe,按照官网的install方法用cygwin制作出model文件,如下图
在任意地方新建文件夹project_test,其内再建文件夹jni,起内容如下
其中Application.mk内容如下
APP_STL := stlport_static
Android.mk的内容如下
LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := libzinnia LOCAL_SRC_FILES := character.cpp feature.cpp libzinnia.cpp param.cpp recognizer.cpp sexp.cpp svm.cpp trainer.cpp LOCAL_CFLAGS := -Werror -DHAVE_CONFIG_H include $(BUILD_STATIC_LIBRARY) # JNI include $(CLEAR_VARS) LOCAL_MODULE := libzinniajni LOCAL_SRC_FILES := libzinniajni.cpp LOCAL_STATIC_LIBRARIES := libzinnia include $(BUILD_SHARED_LIBRARY)
libzinniajni.h的代码如下

在libzinniajni中的com_tomhw_MainActivity为android项目的包名跟activity名字
其余的文件全部都来自zinnia的源码包
用cygwin进入到jni文件夹并用ndk编译($NDK_ROOT为用户在安装ndk时自定义的),具体如下图
如果编译成功的话会在jni的同一级目录中多出libs以及obj文件夹,
其中libs中的armeabi中的.so文件正是所需要的文件
