Google has a comprehensive guide for Remote Debugging Android Devices. As such you can plug an Android device to a Windows, Mac, or Linux computer and access various tools for debugging through Desktop Google Chrome DevTools. This allows to troubleshoot issues on Chrome for Android and in Android WebViews.
