延迟AdMob ads加载

Question

我在我的主要活动中加载一个简单的横幅广告。问题是，每当我启动应用程序时，它在白屏幕上停留大约2秒，然后加载UI。问题不在于应用程序代码，因为在我添加ads之前，应用程序通常会立即启动。这是我加载广告的代码：

在onCreate中：

MobileAds.initialize(this, "ca-app-pub-#######")
        val mAdView: AdView = findViewById(R.id.adView)
        mAdView.visibility = View.GONE
        val adRequest = AdRequest.Builder().build()
        val adView = AdView(this)
        adView.adSize = AdSize.BANNER
        adView.adUnitId = "ca-app-pub-3940256099942544/6300978111"  <- test id
        initializeAds(mAdView, adRequest)

initializeAds()

 fun initializeAds(adView: AdView, adRequest: AdRequest){
        adView.loadAd(adRequest)
        adView.adListener = object : AdListener(){
            override fun onAdLoaded() {
                super.onAdLoaded()
                if (adView.visibility == View.GONE) {
                    adView.visibility = View.VISIBLE
                }
            }

            override fun onAdFailedToLoad(p0: Int) {
                super.onAdFailedToLoad(p0)
                adView.visibility = View.GONE
            }
        }
    }

是否有任何方式可以加载广告而没有用户界面滞后？

好了，伙计们，我终于找到了一个快速的解决办法。我发现MobileAds.initialize(context, id)和AdRequest.Builder().build()是有时滞的。显然，除非完全执行onCreate，否则活动不会完全加载。为了绕过这个问题，我使用Handler来延迟MobileAds.initialize和AdRequest.Builder().build，然后它不会使UI延迟。这是我更新的代码：

       // we can't delay UI tasks so we need initialize adView here - it's not heavy task anyway
        val mAdView: AdView = findViewById(R.id.adView)
        mAdView.visibility = View.GONE

        //delay ads to be displayed 2 sec after Activity is loaded
        Handler().postDelayed({
            MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713")
            initializeAds(mAdView)
        }, 2000)

initializeAds(AdView)

   fun initializeAds(adView: AdView) {
        adView.loadAd(AdRequest.Builder().build())
        adView.adListener = object : AdListener() {
            override fun onAdLoaded() {
                super.onAdLoaded()
                //if ad is loaded just show it
                if (adView.visibility == View.GONE) {
                    adView.visibility = View.VISIBLE
                }
            }

            override fun onAdFailedToLoad(p0: Int) {
                //if we can't show ad just hide it
                super.onAdFailedToLoad(p0)
                adView.visibility = View.GONE
            }
        }
    }

我希望，如果有人正在为同样的问题而挣扎，那将有帮助。

将此用作横幅广告id ca-app-pub-3940256099942544/6300978111

Domin建议您为MobileAds.Initialize()做大约2000 is的延迟。请不要那样做。2秒之后，UI就冻结了！用户会非常生气的。当用户开始使用它时，如果启动速度慢于应用程序没有响应性，那就更好了。
