Firebase AdMob Попытка вызвать виртуальный метод 'boolean java.lang.Boolean.booleanValue ()' для ссылки на пустой объект

Question

Эта проблема показывает только Vivo Phone с Android версии 8.1.0.

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mehindiapp/com.mehindiapp.MainActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference

Я пытался обновить версию библиотеки, но проблема осталась прежней. Я не могу найти основную проблему. Будь то в библиотеках или в коде

Используемые версии Libary:

// Add the Firebase SDK for Google Analytics
implementation 'com.google.firebase:firebase-analytics:17.2.1'
implementation 'com.google.firebase:firebase-core:17.2.1'

// Add the SDK for Firebase Cloud Messaging
implementation 'com.google.firebase:firebase-messaging:20.0.0'

// Add the SDK for Firebase Crashlytics
implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'

// Add the SDK for Firebase AdMob
implementation 'com.google.firebase:firebase-ads:18.2.0'

classpath 'com.google.gms:google-services:4.3.0'

Пожалуйста, кто-нибудь поможет мне, как решить эту проблему. Здесь показана некоторая внутренняя ошибка.
