Unable to load admob ads using custom-tabs solution

[郑小飞]

Hello, I'm using custom tabs on Android to load the page URL (https://developers.google.cn/admob/android/browser/custom-tabs?hl=zh-cn#java) and have also added the following settings (https://developers.google.com/ad-placement/docs/example?hl=zh-cn#support_mobile_apps). Admob ads are initialized successfully, but I'm unable to play them. I observed in logcat that there's a prompt "unable to start service Intent { cmp=com.minigamecloud.center2/androidx.browser.customtabs.PostMessageService } U=0: not found". What could be the cause?
