Detecting the code for an Android device through JavaScript or PHP

With the return of jobs, IPad2 's release seems to be getting hotter on the mobile side of the development topic. Here's a list of some of the biggest competitors in iOS-the Android (Android) system detection method.

JavaScript Judgment method

Searching for the Android word in the user agent string is the most time-saving method:
Copy Code code as follows:
if (Navigator.userAgent.match (/android/i)) {
Do something!
Redirect to Android-site?
window.location = ' http://android.davidwalsh.name ';
}

How to Judge PHP

Again, we can use the Strstr method in PHP to search for Android in the user agent:
Copy Code code as follows:
if (strstr ($_server[' http_user_agent '], ' Android ')) {
Header (' Location:http://android.davidwalsh.name ');
Exit ();
}

In addition, you can use the. htaccess to judge

We can use. htaccess to judge and respond to Android devices!
Copy Code code as follows:
Rewritecond%{http_user_agent} ^.*android.*$
Rewriterule ^ (. *) $ http://android.davidwalsh.name [r=301]

So you have all the three kinds of detection methods for Android devices.
