manifest.xml黄色提示 consider adding at least one Activity with an ACTION-VIEW intent filter

manifest.xml黄色提示：App is not indexable by Google Search; consider adding at least one Activity with an ACTION-VIEW intent filter. See issue explanation for more detail...

官方解释：

To enable Google to crawl your app content and allow users to enter your app from search results, you must add intent filters for the relevant activities in your app manifest. These intent filters allow deep linking to the content in any of your activities. For example, the user might click on a deep link to view a page within a shopping app that describes a product offering that the user is searching for.
要使谷歌能够抓取应用程序内容并允许用户从搜索结果中进入应用程序，必须为应用程序清单中的相关活动添加intent过滤器。这些intent过滤器允许对任何活动中的内容进行深度链接。例如，用户可以单击一个深层链接来查看购物应用程序中的页面，该页面描述了用户正在搜索的产品。

意思是说，如果你的应用配有商品详情页，加上ACTION-VIEW这个过滤器可以让用户在点击广告之后直接进入到详情页，而不是跳转到首页。

解决方法：

        1  忽略警告：

        在app的build中添加如下配置

lintOptions {  
        disable 'GoogleAppIndexingWarning'  
} 

        2 听google的话，manifest.xml创建过滤器并加上这个配置

<action android:name="android.intent.action.VIEW" />
