Custom Android Device Development

One partner for the whole product lifetime

A new device needs more than a working image. It needs the right hardware, a BSP that stays maintained, a build process that doesn't depend on one engineer's machine, a safe way to update devices in the field, and security patches for years. Emteria covers every stage, with our engineers and with the Emteria Hub. You choose the stages you need.

Your own customized OS, built on the chip vendor's official BSP
At least 5 years of security updates per Android version
OTA updates, device management and kiosk mode in one Hub
Help with your Cyber Resilience Act (CRA) obligations

Consulting and architecture

OS version, security, updates and support period: we help you plan the architecture early, so weak spots don't turn into expensive changes later.

Hardware selection

We recommend the SoC or module that fits your product, from NXP, Raspberry Pi, Rockchip, Intel x86 and other platforms: a well-maintained BSP and long availability.

BSP porting and bring-up

We build on the chip vendor's official BSP, bring it up on your board, improve it and keep it maintained. Upgrading or porting to new hardware on request.

OS customization

Branding from the boot animation to the user interface, apps, settings, kiosk mode and more, configured in the browser. Every build is automated, traceable, comes with an SBOM and is signed with your own keys.

Update and device management

Register your devices, provision them with your configuration and manage the OS updates across the fleet in the Emteria Hub, or connect your existing device management solution.

Long-term maintenance

Security patches and new features through OTA updates, at least 5 years per Android version, and an upgrade to a newer Android version before support ends. You decide what is released and when.

Frequently asked questions

What does Emteria do for device makers?

Emteria builds and maintains custom Android operating systems for device makers, from hardware selection and BSP to OTA updates, security patches and CRA support, delivered through the Emteria Hub. Our engineers support each stage of your project, and the Hub keeps the result updated and manageable for years.

How does a project start?

Send us a short description: the SoC or module you have in mind, important peripherals or features, expected units per year, your timeline, and whether the CRA applies to your product. Our engineers get back to you with questions and next steps. You can also try the Emteria Hub for free first.

Is there a minimum project size?

No. We work with prototypes and pilot fleets as well as series production with thousands of devices.

Do we need our own AOSP team?

No. Our engineers take care of BSP setup and onboarding, OS customization and its maintenance. If you have your own team, it works in the Emteria Hub directly and takes over as much as it wants.

Which hardware should we choose?

We recommend the platform that fits your product, from our experience with many boards and chip vendors: an SoC or module with a well-maintained BSP and long availability. You buy the hardware from the vendor of your choice, or bring your own board design.

Can you work with the BSP from our hardware vendor?

Yes. We take the official BSP from your chip vendor or board supplier, onboard it into OS Pipelines and maintain it, also when the vendor has stopped supporting it. If your hardware has no Android BSP yet, we can try porting official Android to it. The effort depends on the SoC and the state of the BSP, so tell us about your board early.

How long do you support an Android version?

At least 5 years of security updates for each major Android version, counted from its release and included in the contract. Before that ends, we upgrade your devices to a newer Android version, so your product stays supported for its whole life. Longer maintenance of one Android version is possible per contract.

Who controls the updates on our devices?

You do. You decide what is released, when, and to which devices. Staged rollouts let you start with a few devices before the whole fleet gets an update.

Will we depend on Emteria?

Your OS builds and signing keys belong to you, and your team can build, release and manage with the Emteria Hub on its own. The Hub runs in our European cloud, as a dedicated instance, or on your own servers. Same Hub, same features. Our engineers help as much as you need.

Can our devices use Google Play?

Most of our customers build without Google services: no certification overhead, full control over the OS. If you need Google Play, talk to us: we work with an experienced, Google-certified partner.

Do you help with the Cyber Resilience Act (CRA)?

Yes. We help device makers meet their CRA obligations on the OS side: vulnerability monitoring, security patch delivery through OTA updates, an SBOM for each OS release, and help with technical documentation and vulnerability reporting. The obligations stay with the manufacturer; we take care of the OS part.

Can you help with device certifications?

We don't certify devices ourselves. We support your certification with the technical information and documentation about the OS that the test lab asks for.

Do we have to use every part of the Emteria Hub?

No. Some customers use only OS Pipelines to build and sign their OS and keep their own device management. Others use OTA updates and device management for the whole fleet. Each workspace is a separate fleet: production, testing, or one per end customer.

Over 15 years of AOSP experience

Our team of AOSP and embedded engineers has built customized Android systems since Android 1.6. We have built and supported many product builders and OEMs across various hardware platforms.

Serving more than 60 countries

Device makers on six continents use Emteria to build and maintain modern digital products for retail, logistics, kiosks, digital signage, HMI, industrial devices and many other use cases.

You remain in full control

Your OS builds and signing keys belong to you. Your team can build, release and manage on its own, and you choose where the Hub runs: in our European cloud, as a dedicated instance or on your own servers.

Security for the whole life of your product

Connected devices stay in the field for many years. We keep them secure with a release process you control. We recommend two releases per year plus urgent fixes for critical vulnerabilities.

Security patches through staged OTA updates
Vulnerability monitoring for your OS
An SBOM for every OS release
Verified boot and signing with your own keys
Android version upgrades before support ends
Help with CRA documentation and vulnerability reporting

Develop a New Android Device

From the first idea to series production and years of updates: we help you plan, build and maintain your own customized OS, and you stay in control of your product.
