This blog post provides a guide on how to debug web pages on the Nokia 8110 (KaiOS) using Chrome OS with Crostini (m75 or later). It builds upon a previous post about using Web IDE for debugging KaiOS devices but focuses on using a Chrome OS environment. The guide outlines the necessary steps, including enabling Crostini USB support, installing required packages like USB tools, ADB, and Fastboot, and configuring udev rules to allow Chrome OS to recognize the Nokia 8110. The post includes commands for installing dependencies and verifying device connectivity.
I created Quick LogCat, a web tool for debugging Android devices without needing adb installed. It uses WebADB.js and the WebUSB API to connect to your device and display logcat output. The tool is useful for on-the-go debugging. It's powerful but also highlights the potential security implications of granting web access to USB devices. This technology opens up exciting possibilities like firmware updates and app sideloading via web interfaces. I'm curious to see what others build with WebUSB and adb access.
Debugging web pages on the Nokia 8110 (KaiOS) can be tricky due to the lack of traditional developer tools. This post outlines the steps I used to successfully debug, involving enabling Developer Mode on the phone, forwarding a port using adb, and connecting to the phone's runtime via Firefox 48's Web IDE.
There's a growing interest in using socket APIs directly within web browsers for various applications, both client-side and server-side. This post lists potential use-cases for outgoing and incoming socket connections, eliminating the need for proxying through web servers. Examples include email clients connecting directly to IMAP/POP3/SMTP, SSH/RDP clients, real-time communication tools like IRC and XMPP, P2P applications like BitTorrent, and direct connections to servers for various purposes like video streaming, Bitcoin, and game multiplayer functionality. For incoming connections, use-cases include hosting servers for many of the aforementioned services (IRC, BitTorrent, HTTP) directly within the browser.
Installing Chrome for Android directly onto an emulator isn't possible, as it's only available via the Play Store. However, you can install the Chromium Test Shell, an open-source, functional version of Chromium without Chrome's usual interface. Although it lacks features like bookmarking and sync, it supports remote debugging. Find recent builds online and install them via adb. I've even created a script to automate downloading, extracting, and installing the latest Chromium Test Shell build, available on GitHub.
In this blog post, I share a simple shell script to help you create your own mobile web testing lab for Android. The script uses adb to connect to attached Android devices, sets up port forwarding for Chrome DevTools, and opens the browser on each device. It's a starting point towards my goal of using a Raspberry PI to host adb and all connected devices, simplifying multi-device testing.
