Android phone browser to determine if the Android client program is installed

The Androidmanifest.xml file on the Android project has the following configuration for activity:

The scheme,host,port,pathof the properties of data in the filter configured in Androidmanifest.xml is identical to the HTML.

The HTML page code looks like this:

<a id= "AppLink" href= "http://192.168.1.9:8088/test/download.html" > View now </a>

So there are two programs that can handle this jump link: One is the browser of the system, and the other is the activity that configures the intent-filter.

If this app is not installed, then this download.html can be forward to the Android App Store and go to the search page based on the parameters and display the results of the installation software. (contains the following code)

<script type= "Text/javascript" >window.location= "market://search?q=com.xxx.xxx";</script>
