🏃 Usage SDK

1. Setup Environment

• Create New Project with Android Studio.

• Place SDK library ttvface.aar into app / libs.

• Include SDK library to app / build.gradle file.

dependencies {
    ...
    implementation files('libs/ttvface.aar')
    ...
}

• Import library in code and call functions.

import com.ttv.face.FaceEngine;

...
// Set License (To obtain license, please contact us)
FaceEngine.getInstance(this).setActivation(license);

// Init with Max Detectable Face Count
FaceEngine.getInstance(this).init(8);

// Detect Face
List<FaceResult> faceInfoList = new ArrayList<>();
faceInfoList = FaceEngine.getInstance(this).detectFace(bitmap);
