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.
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>
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 :)
Add In Your Manifest File
<meta-data
android:name="com.google.android.gms.ads.AD_MANAGER_APP"
android:value="true" />
I think the name should be "APPLICATION_ID" not "APP_ID"
Google Mobile Ads SDK v17.0.0 for Android has just been released, and it comes with these important changes.
Required AndroidManifest.xml changes
Starting in version 17.0.0, if you are an AdMob publisher you are now required to add your AdMob app ID in your AndroidManifest.xml file. Once you find your AdMob app ID in the AdMob UI, add it to your manifest adding the following tag:
<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>
Failure to add this tag will result in the app crashing at app launch with a message starting with The Google Mobile Ads SDK was initialized incorrectly.
What if I'm using Google Ad Manager instead of AdMob?
Publishers using Google Ad Manager will need to declare themselves as an Ad Manager app with a different tag to avoid the same crash:
<manifest>
<application>
<meta-data
android:name="com.google.android.gms.ads.AD_MANAGER_APP"
android:value="true"/>
</application>
</manifest>
See the link for more details.
