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
