Android calling Face[] detect with faceAttributesType

Question

I have succesfully implemented the below:

private FaceServiceClient faceServiceClient =
        new FaceServiceRestClient("xxx", "yyy"); 
private void detectAndFrame(final Bitmap imageBitmap)
{
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
    ByteArrayInputStream inputStream =
            new ByteArrayInputStream(outputStream.toByteArray());
    AsyncTask<InputStream, String, Face[]> detectTask =
            new AsyncTask<InputStream, String, Face[]>() {
                @Override
                protected Face[] doInBackground(InputStream... params) {
                    try {
                        publishProgress("Detecting...");
                        Log.e("face", "detecting");
                        Face[] result = faceServiceClient.detect(
                                params[0],
                                false,         // returnFaceId
                                false,        // returnFaceLandmarks
                                null   // returnFaceAttributes: a string like "age, gender"
                        );

Now I want to get the face attributes like :

Age,Gender,FacialHair

Question 1:

I am importing FACE API 1.0 at the moment, is there any update version?
I am using FACE API on IOS as well and in Android I do not see attributes I can see in IOS like glasses, why?

Question 2:

I need an help on changing the query so it can get attributes like Age,Gender. I tried to change

null   // returnFaceAttributes: a string like "age, gender"

to

age,gender   // returnFaceAttributes: a string like "age, gender"

or "Age, Gender" , or [age, gender] or [Age, Gender] with no luck.

From the interface I see:

public interface FaceServiceClient {
    Face[] detect(String var1, boolean var2, boolean var3, FaceServiceClient.FaceAttributeType[] var4) throws ClientException, IOException;

    Face[] detect(InputStream var1, boolean var2, boolean var3, FaceServiceClient.FaceAttributeType[] var4) throws ClientException, IOException;

and

public static enum FaceAttributeType {
    Age {
        public String toString() {
            return "age";
        }
    },
    Gender {
        public String toString() {
            return "gender";
        }
    },
    FacialHair {
        public String toString() {
            return "facialHair";
        }
    },
    Smile {
        public String toString() {
            return "smile";
        }
    },
    HeadPose {
        public String toString() {
            return "headPose";
        }
    };

How I have to format those parameters to get the values ?

Question 3:

I need to gather and work the output I receive from the call. What are the variables of the object returned? Like number of faces detected, age, gender?

v1.0 is the most current API.

The third argument to detect is an array of enumerated types. You can see a sample app here. The relevant code is thus:

return faceServiceClient.detect(
        params[0],
        false,       /* Whether to return face ID */
        false,       /* Whether to return face landmarks */
        new FaceServiceClient.FaceAttributeType[] {
                FaceServiceClient.FaceAttributeType.Age,
                FaceServiceClient.FaceAttributeType.Gender
        });

The response is an array of faces. The face count would be the length of said array. The age and gender face[n].faceAttributes.age and face[n].faceAttributes.gender, respectively.

Super! I see currently we support: age,gender,headPose,smile,facialHair */ . Any idea when the other values like glasses will be supported also in Android? – czane Feb 05 '18 at 09:35
It should already be there. Is it not? Here's the complete list: https://github.com/Microsoft/Cognitive-Face-Android/blob/994f0b360aac19f1cbd94c759f494bb6ce8a0552/ClientLibrary/lib/src/main/java/com/microsoft/projectoxford/face/FaceServiceClient.java – cthrash Feb 05 '18 at 17:03
It isn't, with implementation 'com.microsoft.projectoxford:face:1.0.0' I just have FaceAttributeType.Age FaceAttributeType.Gender FaceAttributeType.Smile FaceAttributeType.FacialHair FaceAttributeType.HeadPose. Can you please check? – czane Feb 05 '18 at 17:46
Are you pulling packages from [Maven](https://mvnrepository.com/artifact/com.microsoft.projectoxford/vision)? You should be pulling in the latest version, which is 1.0.394 at the moment. – cthrash Feb 06 '18 at 00:18
Error:(85, 20) Failed to resolve: com.microsoft.projectoxford:face:1.0.394 using allprojects { repositories { jcenter() google() maven { url "https://dl.bintray.com/hani-momanii/maven" } } – czane Feb 06 '18 at 07:49
My mistake - that's the version for Vision API. Face API is [here](https://mvnrepository.com/artifact/com.microsoft.projectoxford/face). Version is **1.3.0**. – cthrash Feb 06 '18 at 16:18
Right ok. Build gradle finished, new values kept. Thanks! – czane Feb 06 '18 at 17:39
