这次崩溃是在没有播放服务的设备上还是什么？请帮帮我

这就是HomeActivity onResume

        @Override
        protected void onResume() {
            if (adView != null) {
                adView.resume();
                loadBannerAd();
            }
            super.onResume();
    }



  public void loadBannerAd() {
    if (!localPreferences.IsRemovedAdsPurchased()) {
        if (adView != null) {
            adView.loadAd(new AdRequest.Builder().build());
        }
    }
}
