import com.huawei.hiai.vision.visionkit.common.Frame;//Load the Frame class.
import com.huawei.hiai.vision.visionkit.common.Video;//Load the video class.
import com.huawei.hiai.vision.visionkit.image.detector.AestheticsScore;//Load the aesthetic engine result class.
import com.huawei.hiai.vision.image.detector.AestheticsScoreDetector;//Load the detector class of aesthetic engine.
import com.huawei.hiai.vision.common.VisionBase;//Load the static class for connecting to the service.
import com.huawei.hiai.vision.common.ConnectionCallback;//Load the callback for connecting to the service.
import com.huawei.hiai.vision.visionkit.image.detector.AEVideoResult;//Load the aesthetic engine video result class.

Developing the Function

Perform initialization by using the VisionBase static class, to obtain a connection to the service.

VisionBase.init(mContext, new ConnectionCallback(){
    @Override
    public void onServiceConnect(){
        Log.i(LOG_TAG, "onServiceConnect");
    }

    @Override
    public void onServiceDisconnect(){
        Log.i(LOG_TAG, "onServiceDisconnect");
    }
});

Define the aestheticsScoreDetector instance, and use the context of this app as the input parameter.
