Debugging mobile web applications on actual Android devices using Chrome Developer Tools is a crucial step for developers, as emulators often fail to capture real-time issues. The process requires specific versions of Chrome and Android, USB debugging enabled on the device, and a connection between the device and a workstation. Local hosting of websites can be achieved using frameworks like Angular or tools like WAMPServer, allowing developers to view and test their websites on mobile devices. While manual debugging is possible, platforms like LambdaTest offer a more efficient alternative with instant access to Android browsers and integrated Chrome Developer Tools for cross-browser compatibility testing. LambdaTest also provides a suite of over 100 free online tools to assist developers and testers in various tasks. The importance of testing applications on real devices is emphasized to ensure an accurate user experience before deployment.
