从浏览器下载并安装apk的Html页面

[英]Html page to download and install apk from browser

原文 2012-08-23 18:00:58 8 3 android/ browser/ android-intent/ installation/ apk

I have an app that will be installed by the user from a public webserver (outside android market). 我有一个应用程序将由用户从公共网络服务器（在Android市场之外）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. 所以我在webserver中托管了apk，并指示用户输入url来下载文件，然后“打开”下载的文件进行安装。

But, almost 100% of users are having difficulties to do those simple tasks (they're are not familiar with technology...). 但是，几乎100％的用户都难以完成这些简单的任务（他们不熟悉技术......）。

So, I decided to make a webpage that will simplify the task. 所以，我决定制作一个简化任务的网页。 The page contains a single big button that will: 该页面包含一个大按钮，该按钮将：

Donwload the apk; 下载apk;
After download finish, start "Android's Install Dialog" to install the downloaded apk; 下载完成后，启动“Android安装对话框”安装下载的apk;

Dowloading file is pretty easy, but now my problem is to open the "Install dialog" from browser! 下载文件非常简单，但现在我的问题是从浏览器打开“安装对话框”！

I'm totally newbie about html/javascript and I don't know how to do it (or even if this is possible). 我完全是关于html / javascript的新手，我不知道该怎么做（或者即使这是可能的）。

3 个解决方案

Normally, you just link to the .apk file. 通常，您只需链接到.apk文件。 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'). 当用户单击此类链接时，将下载.apk文件并自动启动安装（使用“您是否要安装此应用程序”这样的对话框）。

So, just <a href="yourdomain.com/yourapp.apk">Download and install...</a> . 因此，只需<a href="yourdomain.com/yourapp.apk">Download and install...</a> 。

Important! 重要！ This only works if your users allow installation from 'Unknown sources' in settings/security. 仅当您的用户允许从设置/安全性中的“未知来源”进行安装时，此方法才有效。

If browser is written not by you, then it doesn't know what to do with downloaded apk file. 如果浏览器不是由您编写的，那么它不知道如何处理下载的apk文件。 Ask user to download something like EasyInstall to install side-loaded apks or place you apk on Google Play. 要求用户下载类似EasyInstall的东西来安装侧载apks或将apk放在Google Play上。 Google Play app on the device knows how to install apk. 设备上的Google Play应用知道如何安装apk。

You need to ensure your webserver that is going to deliver the APK sets the MIME type properly. 您需要确保将要提供APK的Web服务器正确设置MIME类型。 It should be application/vnd.android.package-archive for .apk files. 它应该是.apk文件的application/vnd.android.package-archive 。
