随着乔布斯的回归，iPad2的发布，看来移动端的开发话题越来越火热了。在此列出一些能够在iOS的最大竞争者——安卓(Android)系统的检测方法。
JavaScript判断方法
搜索user agent字符串中的Android单词是最省事儿的方法：
<p><span>1</span><span>.</span><span>if</span><span>(navigator</span><span>.</span><span>userAgent</span><span>.</span><span>match(</span><span>/</span><span>Android</span><span>/</span><span>i)) { <br> </span><span>2</span><span>.</span><span>//</span><span> Do something! </span><span><br></span><span>3</span><span>.</span><span>//</span><span> Redirect to Android-site? </span><span><br></span><span>4</span><span>.</span><span> window</span><span>.</span><span>location </span><span>=</span><span>'</span><span>http://android.davidwalsh.name</span><span>'</span><span>; <br> </span><span>5</span><span>.</span><span> } </span></p>PHP判断方法
同样，我们可以在PHP中使用strstr方法搜索user agent中是否有Android：
<p><span>1</span><span>.</span><span>if</span><span>(</span><span>strstr</span><span>(</span><span>$_SERVER</span><span>[</span><span>'</span><span>HTTP_USER_AGENT</span><span>'</span><span>]</span><span>,</span><span>'</span><span>Android</span><span>'</span><span>)) { <br> </span><span>2</span><span>.</span><span>header</span><span>(</span><span>'</span><span>Location: http://android.davidwalsh.name</span><span>'</span><span>); <br> </span><span>3</span><span>.</span><span>exit</span><span>(); <br> </span><span>4</span><span>.</span><span> } </span></p>另外，可以通过.htaccess来判断
我们可以使用.htaccess来判断和响应安卓设备!
<p><span>1</span><span>.</span><span> RewriteCond </span><span>%</span><span>{HTTP_USER_AGENT} </span><span>^.*</span><span>Android</span><span>.*</span><span>$ <br> </span><span>2</span><span>.</span><span> RewriteRule </span><span>^</span><span>(</span><span>.*</span><span>)$ http</span><span>:</span><span>//</span><span>android.davidwalsh.name [R=301] </span></p>这样你就掌握了全部三种安卓设备的检测方法。
