我有一个应用程序，将通过公开的Web服务器的用户安装（外安卓市场）。

I have an app that will be installed by the user from a public webserver (outside android market).

所以，我主持的Web服务器的apk文件，并指示用户键入的URL下载该文件，然后打开下载的文件进行安装。

So I hosted the apk in webserver and instructed the users to type the url to download the file and then "open" the downloaded file to install it.

不过，用户几乎100％有困难做那些简单的任务（他们不熟悉的技术...）。

But, almost 100% of users are having difficulties to do those simple tasks (they're are not familiar with technology...).

你下载的文件是pretty的方便，但现在我的问题是，打开浏览器，从安装对话框！

推荐答案

通常情况下，你只链接到 .apk文件文件。当用户点击这样的链接， .apk文件文件下载并安装自动启动（用类似这样的对话你想安装此应用程序）。

Normally, you just link to the .apk file. When the user clicks on such a link, the .apk file is downloaded and the installation is automatically started (with a dialog like 'do you want to install this application').

所以，只要＆LT; A HREF =yourdomain.com/yourapp.apk＆GT;下载并安装...＆LT; / A＆GT;

重要！这只能如果您的用户允许从设置/安全未知来源的安装。

Important! This only works if your users allow installation from 'Unknown sources' in settings/security.
