通过浏览器直接打开Android应用程序

实现效果

如下图所示,在手机浏览器中访问京东的手机版网站(m.jd.com),顶部会有一个广告图,点击这个广告图,如果手机上已经安装了京东App,则直接打开,如果没有安装,则开始下载。

实现方式

1.为Android应用的启动Activity设置一个Schema,如下:

<data android:host="splash" android:scheme="cundong"/>

 

2.用户点击浏览器中的链接时,在动态创建一个不可见的iframe,并且让这个iframe去加载步骤1中的Schema,如下:

var ifr = document.createElement('iframe');
ifr.src="cundong://splash"

 

3,如果在指定的时间内没有跳转成功,则当前页跳转到apk的下载地址(或下载页),如下:

window.location = download_url;
