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.
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 :)
