我们建议您遵循以下几项最佳做法,以确保使用 IMA SDK for Android 时您的应用可在 Android TV 上正常运行。
首先,熟悉开发 Android TV 应用。具体而言,请确保按照入门指南中的说明针对 TV 设置 activity。此外,您还需要处理 TV 导航,确保用户可以在 Android TV 上顺畅导航您的应用。
处理可跳过式广告
SDK 针对类似 TV 的设备优化了可跳过式广告格式,例如移除了与了解详情按钮互动的功能。默认情况下,当“跳过”按钮可用时,SDK 会将焦点设置为“跳过”按钮,以便用户在 Android TV 上跳过广告。因此,无需执行额外的操作即可支持可跳过的广告。
您可以通过调用 AdsRenderingSettings.setFocusSkipButtonWhenAvailable()
来配置此项。
如需详细了解支持的广告,请查看兼容性矩阵。
处理 VAST 图标后备图片
IMA SDK 会检测、呈现并处理用户与 VAST 图标后备图片的互动情况。您的应用应监听 ICON_TAPPED
和 ICON_FALLBACK_IMAGE_CLOSED
事件,以处理使用“为什么显示该广告”(WTA) 的广告的播放。
添加一个布尔值,以跟踪是否展示 VAST 图标后备图片。然后,监听 ICON_TAPPED
和 ICON_FALLBACK_IMAGE_CLOSED
以处理围绕 VAST 图标后备图片的广告播放。请参阅以下代码段,通过示例了解高级示例中如何处理此过程。
