HMS Map toolkit - onMapReady() not called after getMapAsync() calling

Question

I am working with HMS Maps, for this I follow their documentation.
For this query I tried this link. I added SHA-256 key and agconnect-services.json file too.
The Steps which I did are:

dependency in app gradle: implementation 'com.huawei.hms:maps:6.0.0.301'
in app gradle: apply plugin: 'com.huawei.agconnect'
My root gradle is:

buildscript {
    repositories {
        maven { url 'http://developer.huawei.com/repo/' }
        google()
        jcenter()
        mavenCentral()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath 'com.google.gms:google-services:4.3.3'
        classpath 'com.huawei.agconnect:agcp:1.2.1.301'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.7.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven {url 'http://developer.huawei.com/repo/'}
        google()
        jcenter()
        mavenCentral()
        maven {
            url 'https://jitpack.io'
        }

        maven {
            url "https://github.com/QuickBlox/quickblox-android-sdk-releases/raw/master/"
        }

    }
}

I added SHA-256 key at AppGallery connect.
Enabled MapApi from AppGallery connect.
Downloaded and added "agconnect-services.json" file in my project.

After resolving some thread related issues, I am able to produce logcat errors and it is saying that "Illegal FingerPrint".
I know, it is about some integration issues with the AppGallery but I am unable to get it that what I am missing, I am following all the steps.
**Logcat is:**

Answer 1

I am not sure that why it is happening, I talked to Huawei developers regarding this issue, I was doing this in a fragment but when I tried this in an activity, it works perfectly. Now I am doing it in a separate Activity. (I created that activity with the built in method of HMS toolkit.)
