How to use Java bindings of OpenCV with Android Studio and Gradle

The source

https://github.com/bytedeco/javacpp-presets

Why I write this

Beacuse they didn’t make it clear about how can I use their libs.
I spent 6 hours to figure out how can I simply import it.

The Code

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.god_loves_you"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true  //ADD THIS LINE
    }

    packagingOptions {
        exclude('META-INF/native-image/android-x86_64/jnijavacpp/jni-config.json')
        exclude('META-INF/native-image/android-x86_64/jnijavacpp/reflect-config.json')
        exclude('META-INF/native-image/android-arm64/jnijavacpp/jni-config.json')
        exclude('META-INF/native-image/android-arm64/jnijavacpp/reflect-config.json')
    }

    dependencies {
        implementation 'com.android.support:multidex:1.0.3'

        implementation group: 'org.bytedeco', name: 'javacpp', version: '1.5.4'
