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

Question

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:

Why does this happen? I tried to research the issue, but I can't find any solutions. It seems to be an a new still unsolved issue.

This happened due to updated AdMob SDK. Now you need to add appID in your manifest file.

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

You can get appID from here -->Google addmob -->Select app --> App Settings --> App ID.

You can read more from here ads-developers.

If you want to use test ads before putting your own id check the AdMob test ids from here developers.google.

Hope this will help you. Thanks :)
