本快速入门指南介绍了如何初始化 Google 移动广告 SDK。在初始化调用期间,中介适配器也会初始化。请务必在初始化完成后再加载广告,以验证每个广告联盟是否都可完全参与第一个广告请求。
以下示例代码展示了如何在发出广告请求前检查每个适配器的初始化状态。
MobileAds.Initialize((InitializationStatusinitializationStatus)=>
{Dictionary<string,AdapterStatus>map=initializationStatus.getAdapterStatusMap();foreach(KeyValuePair<string,AdapterStatus>keyValuePairinmap){stringclassName=keyValuePair.Key;AdapterStatusstatus=keyValuePair.Value;switch(status.InitializationState){caseAdapterState.NotReady:// The adapter initialization did not complete.Debug.Log($"Adapter: {className} is not ready.");break;caseAdapterState.Ready:// The adapter was successfully initialized.Debug.Log($"Adapter: {className} is initialized.");break;}}});

It is important to wait for initialization to complete before\nyou load ads in order to verify full participation from every ad network on the\nfirst ad request.\n| **Important:** Bidding adapters require you to explicitly initialize Google Mobile Ads SDK.\n\nThe following sample code shows how you can check each adapter's initialization\nstatus prior to making an ad request. \n\n MobileAds.Initialize((InitializationStatus initializationStatus) =\u003e\n {\n Dictionary\u003cstring, AdapterStatus\u003e map = initializationStatus.getAdapterStatusMap();\n foreach (KeyValuePair\u003cstring, AdapterStatus\u003e keyValuePair in map)\n {\n string className = keyValuePair.Key;\n AdapterStatus status = keyValuePair.Value;\n switch (status.InitializationState)\n {\n case AdapterState.NotReady:\n // The adapter initialization did not complete.\n Debug.Log($\"Adapter: {className} is not ready.\");\n break;\n case AdapterState.Ready:\n // The adapter was successfully initialized.\n Debug.Log($\"Adapter: {className} is initialized.\");\n break;\n }\n }\n }); \n https://github.com/googleads/googleads-mobile-unity/blob/0f0ef22a4a4b1894951539831f9e3947ff634a75/samples/HelloWorld/Assets/Snippets/MediationSnippets.cs#L13-L32\n\n\u003cbr /\u003e\n\nUse banner ads with mediation\n\nMake sure to disable refresh in all third-party ad source UIs for banner ad\nunits used in mediation. This prevents a\ndouble refresh since Ad Manager also triggers a refresh\nbased on your banner ad unit's refresh rate.\n\nUse native ads with mediation\n\nThe following are some best practices to consider when implementing native\nmediation.\n\nNative ad presentation policy\n: Each ad network has its own policies. When using mediation, it's important to\n remember that your app still needs to abide by the policies of the mediated\n network that provided the ad.\n\nUS states privacy laws and GDPR\n\nIf you need to comply with the [U.S. states privacy\nlaws](//support.google.com/admanager/answer/9561023) or [General Data Protection\nRegulation (GDPR)](//support.google.com/admanager/answer/7666366), follow the\nsteps in [US state regulations\nsettings](//support.google.com/admanager/answer/10115735) or [GDPR\nsettings](//support.google.com/admanager/answer/10113006#adding_ad_partners_to_published_gdpr_messages) to add your\nmediation partners in Ad Manager Privacy \\& messaging's\nUS states or GDPR ad partners list.
