人脸识别1：1对比（一）

本项目采用了eyekey 第三方接口，实现了自选图片人脸识别和两张图片的1：1对比，可返回比对相似度信息，具体步骤如下：

一、所需权限

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

二、第三方app id app key

<meta-data android:name="appkey" android:value=""/>
<meta-data android:name="appid" android:value=""/>

本应用采用的eyekey 第三方接口，可自行去注册，以上代码放到配置文件中

三、添加依赖

    compile "com.squareup.retrofit2:retrofit:2.1.0"
    compile "com.squareup.retrofit2:converter-gson:2.1.0"

retrofit使用参见：https://www.jianshu.com/p/308f3c54abdd

导入sdk,如图放入文件路径下：

四、布局文件

1：1对比

页面两个ImageView 一个button 一个textView，点击imageView 选择本地图片
