AirMap won't find import

The build error I see is-
error: cannot access OnMapChangedListener class file for com.mapbox.mapboxsdk.maps.MapView$OnMapChangedListener not found

Here's my Fragment

package com.example.mapboxhelloworld;

Here's my applications build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"


    defaultConfig {
        applicationId "com.example.mapboxhelloworld"
        manifestPlaceholders = ['appAuthRedirectScheme': applicationId]
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    //mapbox
    implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:8.4.0'

    //airmap
    implementation 'com.airmap.airmapsdk:airmapsdk:3.0.0'

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

Here's my projects build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
        //mapbox
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven{
            url "https://maven.google.com"
        }
        maven {
            url "https://jitpack.io"
        }
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Here's my json.config file-

{
  "airmap": {
    "api_key": "MY_API_KEY",
    "client_id": "MY_CLIENT_ID",
    "callback_url": null
  },
  "mapbox": {
    "access_token": "MY_MAPBOX_ACCESS_TOKEN"
  }
}

What I have tried-
1) Going over the dependencies to make sure I'm not missing something.
2) Tried isolating this problem. Looks like findViewByID seems to be picking up on the problem. Could I be making an error in the way I'm using this method?
3) Checked my imports and added all recommended imports by android studio.
4) Instead of implementing the interface I tried creating new a class variable of OnMapDataChangeListener type and making the appropriate changes. No luck.

NOTE- I'm using my public mapbox access token in the config.json file. Notice that OnMapDataChangeListener is different from OnMapDataChangedListener. They're 2 different classes.

PS- I'm sorry about the amount of code. It can't be helped.
