AndroidManifast警告App is not indexable by Google Search

在AndroidManifest.xml文件中，整个<Application>警告：

Warning: App is not indexable by Google Search; consider adding at least one Activity with an ACTION-VIEW intent filter. See issue explanation for more details.

官方文档：

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Google能够抓取您的应用内容并允许用户从搜索结果中进入您的应用，您必须为manifest中的相关活动添加intent filters。它们允许深入链接到您的任何活动中的内容。例如，用户可以点击深层链接以查看购物应用中的页面，该页面描述用户正在搜索的产品。

解决方法：

1.按照提示添加intent-filter 

在AndroidManifest.xml文件中，至少一个activity的intent-filter中添加

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

2.忽略警告

在app的build.gradle中添加下列代码：

lintOptions {  
        disable 'GoogleAppIndexingWarning'  
} 

（完）
