app端使用活体检测，通过活体检测后，采集人像，base64格式，调接口后台判断人脸对比结果返回给app
1.官网地址：
人脸识别_人脸检测_人脸对比_人脸搜索_活体检测_百度智能云 (baidu.com)
里面有详细的集成步骤和说明
2.申请license
3.下载license拷贝到工程的assets目录
4.将faceplatform-ui以module方式集成项目
4.1在build.gradle 里添加
implementation project(':faceplatform-ui')
4.2在settings.gradle里添加
include ':faceplatform-ui'
faceplatform-ui里集成了faceplatform
5.混淆设置
-keep class com.baidu.vis.unified.license.** {*;}
-keep class com.baidu.liantian.** {*;}
-keep class com.baidu.baidusec.** {*;}
-keep class com.baidu.idl.main.facesdk.** {*;}
6.初始化sdk，前判断权限
if (EasyPermissions.hasPermissions(
this,
android.Manifest.permission.CAMERA
)
) { //权限判断
startBaiduFace() //初始化百度sdk
} else {
AlertDialog.Builder(this).setTitle("提示信息")
.setCancelable(false)
.setMessage("因涉诈安全要求，我们需要您提供相机权限，用于人脸识别。如您拒绝授权，将无法正常登录，是否允许。")
.setPositiveButton("开启权限") { _, _ ->
ActivityCompat.requestPermissions(
this,
arrayOf(android.Manifest.permission.CAMERA),
0X12
)
}.setNegativeButton("取消", object : DialogInterface.OnClickListener {
override fun onClick(p0: DialogInterface?, p1: Int) {
hideDialog()
finish()
}
}).create().show()
}
fun startBaiduFace() {
//初始化SDK
FaceSDKManager.getInstance()
.initialize(this, "sunlightat0707-face-android",
"idl-license.face-android", object : IInitCallback {
override fun initSuccess() {
//初始化成功
//设置采集配置
if (!BaiDuFaceConfig.initLicenseSuccess()) {
return
}
//跳转到带活体检测的界面
startActivity(
Intent(
this,
FaceLivenessExpActivity::class.java
)
)
}
override fun initFailure(errCode: Int, errMsg: String) {
//初始化失败提示
CoroutineScope(Dispatchers.Main).launch(Dispatchers.Main) {
ToastUtils.showToast(
this,
"人脸功能初始化失败 = $errCode, $errMsg"
)
}
hideDialog()
finish()
}
})
}
