Registering an Xmagic listener
This API is used to configure the callback of facial keypoints and other data.
Version 2.6.0 and earlier versions use the following method.
void setYTDataListener(XmagicApi.XmagicYTDataListener ytDataListener)
﻿
﻿
public interface XmagicYTDataListener {
    void onYTDataUpdate(String data)
}
Version 3.0.0 uses the following method.
void setAIDataListener(XmagicApi.OnAIDataListener aiDataListener)
﻿
public interface OnAIDataListener {
    void onFaceDataUpdated(List<TEFaceData> faceDataList);
    void onHandDataUpdated(List<TEHandData> handDataList);
    void onBodyDataUpdated(List<TEBodyData> bodyDataList);
    void onAIDataUpdated(String data); //This method is a new method added in version 3.0.0, and the data structure is consistent with the XmagicYTDataListener interface used in previous versions.
}
onYTDataUpdate and onAIDataUpdated returns a JSON string structure that contains the information of up to 5 faces:
{
 "face_info":[{
  "trace_id":5,
  "face_256_point":[
    180.0,
    112.2,
    ...
  ],
  "face_256_visible":[
    0.85,
    ...
  ],
  "out_of_screen":true,
  "left_eye_high_vis_ratio:1.0,
  "right_eye_high_vis_ratio":1.0,
  "left_eyebrow_high_vis_ratio":1.0,
  "right_eyebrow_high_vis_ratio":1.0,
  "mouth_high_vis_ratio":1.0
 },
 ...
 ]
}
