I need a seasoned Android embedded developer to build a custom firmware image for a 4-inch Android media player currently running stock Android. When the unit powers on it must jump straight into a single kiosk app with no opportunity for users to exit, pull down the notification shade, enter Settings, or install additional applications. Core app behaviour • The kiosk app only needs to handle media playback and must play video, audio, and image files smoothly in a continuous, loopable playlist. • All other Android applications, system dialogs, and navigation elements have to be completely hidden or disabled. System-level requirements • Full kiosk lockdown (blocked back/home buttons, notification bar, recent-apps list, etc.). • System Settings, Google Play, and USB debugging must be inaccessible to end users. • Firmware must include an OTA update mechanism so I can push new versions remotely without physical access to the devices. • Remote device management will be carried out from a companion mobile app (Android/iOS). The firmware therefore needs a lightweight management agent that can: – register the device with my backend on first boot, – report basic health metrics (online/offline state, storage, battery), – accept incoming commands such as “update firmware”, “reboot”, or “push new playlist”. Development & tooling AOSP source modification, Android Studio, fastboot/adb, and an OTA update framework of your choice are all acceptable as long as the final image can be flashed easily and remains stable over long unattended run-times. Deliverables 1. Flashable firmware image (.img) for the target hardware. 2. Source code & build instructions (so I can reproduce the image). 3. Kiosk media-playback app with playlist support. 4. Embedded management agent with documented REST endpoints used by the mobile admin app. 5. Step-by-step guide for deploying OTA updates. Acceptance criteria • Device powers straight into the kiosk app within 20 s of cold boot. • No exit paths from the kiosk UI are discoverable through touch, hardware keys, or USB. • Video (1080p), audio (AAC/MP3), and images (JPEG/PNG) loop for 24 h without glitching or memory leaks. • OTA update installs a test package and reboots successfully. • Remote reboot, playlist push, and health ping commands are executed and acknowledged in under 10 s on a stable Wi-Fi connection. If you have shipped similar embedded Android or digital-signage projects before and can hit these checkpoints reliably, I’d love to work with you.

Hi, I am an embedded systems engineer with over 16 years of experience in Android firmware, AOSP customization, kiosk lockdown, OTA updates, and unattended digital-signage style products. I can build the firmware so the 4-inch media player boots directly into a locked kiosk player, hides Settings/Play/notifications/navigation, blocks user escape paths, and runs a loopable playlist for video, audio, and images. I can also add the lightweight management agent for first-boot registration, health reporting, remote reboot, playlist push, and firmware update commands, with the REST endpoints documented for your companion app. My first step would be to confirm the exact SoC/board, Android version, bootloader status, and whether vendor BSP/source is available, because those details decide the cleanest OTA and lockdown path. After that I can deliver the reproducible build, flashable image, kiosk app, OTA deployment guide, and test the long-run playback/update checkpoints you listed. Please contact me to discuss the target hardware and backend API details.
