Microsoft Emotion API: Android Client Library & Sample

This repo contains the Android client library & sample for the Microsoft Emotion API, an offering within Microsoft Cognitive Services, formerly known as Project Oxford.

The client library

This client library is a thin Java client wrapper for the Microsoft Emotion REST API.

The easiest way to consume the client library is to add com.microsoft.projectoxford.emotion package from Maven Central Repository.

To find the latest version of client library, go to http://search.maven.org, and search for "com.microsoft.projectoxford".

To add the client library dependency from build.gradle file, add the following line in dependencies.

dependencies {
    //
    // Use the following line to include client library from Maven Central Repository
    // Change the version number from the search.maven.org result
    //
    compile 'com.microsoft.projectoxford:emotion:1.0.0'

    // Your other Dependencies...
}

To do add the client library dependency from Android Studio:

From Menu, Choose File > Project Structure
Click on your app module
Click on Dependencies tab
Click "+" sign to add new dependency
Pick "Library dependency" from the drop down list
Type "com.microsoft.projectoxford" and hit the search icon from "Choose Library Dependency" dialog
Pick the Project Oxford client library that you intend to use.
Click "OK" to add the new dependency

Order expressions

You can call the function ToRankedList from the Scores class, for example:

ASCENDING

List<Map.Entry<String, Double>> collection = scores.ToRankedList(Order.ASCENDING);

DESCENDING

List<Map.Entry<String, Double>> collection = scores.ToRankedList(Order.DESCENDING);

The sample

This sample is an Android application to demonstrate the use of Emotion API.

It demonstrates emotion detection from an image. It can identify people's faces and interpret their emotions.

Requirements

Android OS must be Android 4.1 or higher (API Level 16 or higher)

Build the sample

You must obtain a subscription key for Emotion API and Face API by following instructions on our website. Please note that Emotion API and Face API requires two different subscriptions.
Start Android Studio and open project from Emotion > Android > Sample folder.
In Android Studio -> "Project" panel -> "Android" view, open file "app/res/values/strings.xml", and find the line "Please_add_the_emotion_subscription_key_here;". Replace the "Please_add_the_emotion_subscription_key_here" value with your Emotion subscription key string from the first step. If you cannot find the file "strings.xml", it is in folder "Sample\app\src\main\res\values\string.xml".
In Android Studio, select menu "Build > Make Project" to build the sample, and "Run" to launch this sample app.

Run the sample

In Android Studio, select menu "Run", and "Run app" to launch this sample app.

Once the app is launched, click on buttons to use samples of between different scenarios, and follow the instructions on screen.

Microsoft will receive the images you upload and may use them to improve Emotion API and related services. By submitting an image, you confirm you have consent from everyone in it.

If you want to know what is the name of the expression with more value then you might call getExpressionName() from the Score class
