Html page to download and install apk from browser

问题:

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

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.

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

So, I decided to make a webpage that will simplify the task. The page contains a single big button that will:

• Donwload the apk;
• After download finish, start "Android's Install Dialog" to install the downloaded apk;

Dowloading file is pretty easy, but now my problem is to open the "Install dialog" from browser!

I'm totally newbie about html/javascript and I don't know how to do it (or even if this is possible).

回答1:

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').

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

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

If browser is written not by you, then it doesn't know what to do with downloaded apk file. Ask user to download something like EasyInstall to install side-loaded apks or place you apk on Google Play. Google Play app on the device knows how to install apk.

You need to ensure your webserver that is going to deliver the APK sets the MIME type properly. It should be application/vnd.android.package-archive for .apk files.
