App crashes on start (Android)

[AwFaGi]

I've been trying to make it work for 3 days. Also, i try to make QtAdMobApp (WidgetApp). It doesn't work. Sometimes different problems while compiling appear. In the other situations, when apk is ready, it crashes on start. Help me please.

Which Google Ads SDK version are you using?
From Google Mobile Ads SDK version 17.0.0 onwards, it is also required to add the following to the AndroidManifest

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

as is explained here: https://developers.google.com/admob/android/quick-start
It also states "Important: This step is required as of Google Mobile Ads SDK version 17.0.0. Failure to add this tag results in a crash with the message: The Google Mobile Ads SDK was initialized incorrectly."

Hope this helps,
