[FIXED] Unable to get provider com.google.android.gms.ads.MobileAdsInitProvider: java.lang.IllegalStateException

Issue

I update my Android Studio (3.2.1) and its sdk to the latest version. After that it required a manual update for Manifest by adding these tags:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@drawable/ic_launcher"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:ignore="AllowBackup,GoogleAppIndexingWarning">

    <meta-data
        android:name="com.google.android.gms.ads.APP_ID"
        android:value="ca-app-pub-#############"/>

    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".NewActivity" />
    <activity android:name=".PreviewActivity" />
    <activity android:name=".EditActivity" />
    <activity
        android:name=".preferencesdata.AboutActivity"
        android:theme="@style/Theme.AppCompat.DayNight.NoActionBar" />
    <activity android:name=".preferencesdata.SettingsActivity"
        android:label="@string/settings">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value=".MainActivity"/>
    </activity>
</application>

whereby instead the app ID I put the real id of my app. The value has also been changed to the right Ad Unit id as shown here https://developers.google.com/admob/android/quick-start. I also called this function in the MainActivity.kt:

MobileAds.initialize(this, resources.getString(R.string.banner_ad_unit_id)) 

However, the problem could not be solved. It still prints as follows:

E/AndroidRuntime: FATAL EXCEPTION: main

Could someone tel me why it does happen or help me to solve it? I tried to google the issue, but there are no solutions. It seems to be an a new still unsolved issue. Many thanks in advance.

Solution

Google gave update for the Google ads so if you update your Admob library in gradle then you need to add this in your manifest.

<manifest>
   <application>
      <!-- TODO: Replace with your real AdMob app ID -->
      <meta-data
          android:name="com.google.android.gms.ads.APPLICATION_ID"
          android:value="ca-app-pub-################~##########"/>
  </application>
</manifest>
