Detecting Android devices via 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:

 
  
  

  
   
   
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:

 
  
  

  
   
   
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!

 
  
  

  
   
   
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.
