   implementation 'com.google.android.gms:play-services-ads:17.1.1'

}

These are my codes.I'm using Admob to display the ads in my app.When I add this code:"'com.google.android.gms:play-services-ads:17.1.1'" and sync , my apps crash.

After that I go to Admob official website and found that this version is for 'com.android.support:appcompat-v7:26.1.0' version. But when I change the compileSdkVersion to 26, my apps still crash....

I have test the code without this code:"'com.google.android.gms:play-services-ads:17.1.1'" and it can run.Im sure that this code is the problem but i have no idea how to correct it.

Could anyone help to solve my problem?
Thank you.

Because with "com.google.android.gms:play-services-ads:17.1.1"
You need to update something.

You have to Update your AndroidManifest.xml

<manifest>

    <application>

        <meta-data

            android:name="com.google.android.gms.ads.AD_MANAGER_APP"

            android:value="true"/>

    </application>

</manifest>

And with this:

<manifest>

    <application>

        <!-- Sample AdMob App ID: ca-app-pub-3940256099942544~3347511713 -->

        <meta-data

            android:name="com.google.android.gms.ads.APPLICATION_ID"

            android:value="[ADMOB_APP_ID]"/>

    </application>

</manifest>

You can check these links for more detail informations.

https://developers.google.com/ad-manager/mobile-ads-sdk/android/quick-start#update_your_androidmanifestxml

https://developers.google.com/admob/android/quick-start#update_your_androidmanifestxml

Otherwise You have to use "com.google.android.gms:play-services-ads:16.0.0"

Use "com.google.android.gms:play-services-ads:16.0.0", the new 17.1.1 change some code implementation, ie, you need do that in ur source too, or back to 16.0.0 for now...

will fix your error for while...

Go to Admob - Select App - App Setting - App ID copy the value from App ID

Now add this (change this android:value="paste the App ID value you copy from your admob app" )

<meta-data

            android:name="com.google.android.gms.ads.APPLICATION_ID"

            android:value="ca-app-pub-111100000000~1111111"/>

meta-data into AndroidManifest.xml file

No need to add anything in APPLICATION_ID from android:name="com.google.android.gms.ads.APPLICATION_ID"

This will work!
