Java 在Android Studio中实现人脸检测的照片标记

Java 在Android Studio中实现人脸检测的照片标记,java,android,android-studio,face-detection,Java,Android,Android Studio,Face Detection,我正在开发一个android应用程序,该程序使用人脸检测在图像上标记照片。该应用程序就像Facebook检测到照片中的人脸后在Facebook上标记照片一样 我的主要问题是,我不知道如何返回faceID和做图像标记,我做了很多尝试,但没有成功。这是我的人脸检测编码 package com.application.nurfatinahjannah.muka; import android.os.Bundle; import com.microsoft.projectoxford.face.*;
