Crash on clicking full screen ads using google ad mob

I have implemented Google ads by using this library
implementation 'com.google.android.gms:play-services-ads:22.1.0'

Below code

 mAdView = new AdManagerAdView(getActivity());
    adContainerView = view.findViewById(R.id.ad_view_container);
    mAdView.setAdUnitId(adID);
    request = new AdManagerAdRequest.Builder().build();
    adSize = getAdSize();
    // Step 4 - Set the adaptive ad size on the ad view.
    mAdView.setAdSize(adSize);
    adContainerView.addView(mAdView);
    mAdView.loadAd(request);

But getting crash on clicking some ads
Process: com.indiatoday.mobiletak, PID: 13897

Please help not get the way out.

Thanks & Regards

Finally, find that bug. Actually, it was due to a third-party SDK clarity, which tracks tap events on the app. That's why on clicking ads they were crashing.

Thanks
