Integrating Orbot library in Android apps

[HAAMTHELORD]

I'm developing an open source privacy concerned android browser app in kotlin, i tried using orbot library to mask user's ip, but when i used the below imported dependencies, it doesn't work !
In my build.gradle,
implementation 'org.torproject:android-orchestra:1.0.0' implementation 'org.torproject:android-orbot:1.0.0'

In my MainActivity.kt ,

import org.torproject.android.core.LocaleHelper import org.torproject.android.service.OrbotConstants import org.torproject.android.service.util.Prefs import org.torproject.android.ui.LogBottomSheet import org.torproject.android.ui.v3onionservice.PermissionManager

My Error,

Unresolved reference: torproject

How to solve it? What are the Correct dependencies ?
