I created Index.php controller for that at app/code/RH/Helloworld/Controller/Index/ and add this below code :

Copy Code


<?php
/**
 * Created By : Rohan Hapani
 */
namespace RH\Helloworld\Controller\Index;

class Index extends \Magento\Framework\App\Action\Action {

    /**
     * @var \Magento\Framework\View\Result\PageFactory
     */
    protected $resultPageFactory;

    /**
     * @var \Magento\Framework\HTTP\Header
     */
    protected $httpHeader;

    /**
     * @param \Magento\Framework\App\Action\Context      $context
     * @param \Magento\Framework\HTTP\Header             $httpHeader
     * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
     */
    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\HTTP\Header $httpHeader,
        \Magento\Framework\View\Result\PageFactory $resultPageFactory
    ) {
        $this->httpHeader = $httpHeader;
        $this->resultPageFactory = $resultPageFactory;
        parent::__construct($context);
    }
    /**
     * Detect Mobile view or Desktop View
     *
     * @return void
     */
    public function execute() {
        $resultPage = $this->resultPageFactory->create();
        $userAgent = $this->httpHeader->getHttpUserAgent();
        $isMobile = \Zend_Http_UserAgent_Mobile::match($userAgent, $_SERVER);
        if ($isMobile) {
            $resultPage->getConfig()->getTitle()->prepend(__("Mobile View")); // Mobile view logic add here
        } else {
            $resultPage->getConfig()->getTitle()->prepend(__("Desktop View")); // Desktop view logic add here
        }
        return $resultPage;
    }

}

You can add this above code in your controller or any file. You need to inject \Magento\Framework\HTTP\Header class into your construct.

In above code, if condition is true then, it’s mobile device otherwise, it will be desktop device. If you want to add code logic for mobile view then, you need to add inside if condition. For desktop view, you need to add code inside else condition.

That’s it !!!
