How to Get Provider Com.Google.Android.Gms.Ads.Mobileadsinitprovider: Java.Lang.Illegalstateexception

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

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 :)

Android 8.1 Unable to get provider com.google.android.gms.ads.MobileAds!!! apk crash

There are 2 ad ids in Admob.

1). appID

2). adUnitID

For an app whatever the your ad type you use, the appID is same. But the the adUnitID differs for the each ad type you use. For example, you can have both banner ads and interstitial ads in the App. For both of those ad types appID is same, but the adUnitID differs.

As per your code you have used the same ID everywhere, which is not correct. You need to use appID, adUnitID in appropriate places. In layout xml, where you declare the ad unit it should have adUnitID and other places appID.

Manifest.xml

<meta-data
    android:name="com.google.android.gms.ads.APPLICATION_ID"
    android:value=**appID**/>

MainActivity Layout

<com.google.android.gms.ads.AdView
android:id="@+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_gravity="bottom"
android:layout_weight="1"
ads:adSize="SMART_BANNER"
ads:adUnitId=**adUnitID**>

HomeActivity.java

MobileAds.initialize(this, **appID**);

So in your case, it seems that you have used adUnitID for the the places you should have used appID. That's probably why it throws the error as in
