无法加载admob ad errror：3 ERROR_CODE_NO_FILL

Question

我无法加载广告错误：3。

我已经尝试过请求欧洲用户的同意。但是它没有用，我已经等了7天了。

class MainActivity{
    lateinit var mAdView: AdView
    override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    getUserConsent()
    }

    @SuppressLint("HardwareIds")
    private fun getUserConsent() {
    try {
    if (!isConsentYet) {
    val msg = "Your privacy policy"

    @SuppressLint("InflateParams")
    val view = LayoutInflater.from(this@MainActivity)
                    .inflate(R.layout.dialog_consent, null, false)

    val d = AlertDialog.Builder(this)
                    .setView(view)
                    .setCancelable(false)
                    .setTitle("User Consent")
                    .setIcon(R.mipmap.ic_launcher)
                    .create()
    view.txtAlertMsg.text = Html.fromHtml(msg)
    view.btnAccept.setOnClickListener {

    ConsentInformation.getInstance(this@MainActivity).addTestDevice(
                        Settings.Secure.getString(
                            contentResolver,

            override fun onAdOpened() {

    that
                // covers the screen.

                Log.w("AdListener", "onAdClicked")
            }

            override fun onAdLeftApplication() {

                Log.w("AdListener", "onAdLeftApplication")
            }

            override fun onAdClosed() {
                // Code to be executed when the user is about to 
    return
                // to the app after tapping on an ad.
                Log.w("AdListener", "onAdClosed")
            }
       }
}

总是，我在几天内收到了ERROR_CODE_NO_FILL。

谷歌解释

ERROR_CODE_NO_FILL广告请求已成功，但由于缺少广告资源，未返回任何广告。

但是，如果您能够看到测试广告，那么您的代码就没有任何问题。 可能谷歌支持可以帮助你，他们会要求你的AdsUnitId和appId进行测试并回答你的真正问题。 这里
