Closing the Android Testing Gap

As Android applications grow more sophisticated, so do the demands on testing infrastructure. Teams building with ARM64-native libraries, on-device AI frameworks, and the latest Android releases need a virtual testing environment that keeps pace. The gap between cloud emulator architecture and real device architecture has been a known constraint. ARM-native virtual devices close it.

The root cause is architectural. x86-based cloud emulators handle a large share of Android testing well and remain a strong fit for most suites. Where they have to stretch is toward ARM64-native code. Modern Android apps, and the devices your users carry, run on ARM, so tests running on x86 pass through a binary translation layer. That layer approximates the device rather than matching it, which introduces noise, slows execution, and can produce results that diverge from real-world behavior on the newest hardware. 

Solving this at CI/CD scale has been a known gap in enterprise testing. Sauce Labs Virtual Device Cloud now closes it. 

Introducing ARM-native virtual devices for Android 

Virtual Device Cloud now runs ARM-native virtual Android execution at CI/CD scale. That means cleaner, more trustworthy results that hold up as your users move onto newer ARM64 devices, plus compatibility with ARM64-native libraries that traditional x86 emulators aren't built to run. 

For teams building with native development kits or ARM-native cryptography libraries, this removes a hard blocker. For teams chasing test reliability as release cycles accelerate, it closes a fidelity gap that has been costing engineering time for years. 

What changes in practice

Fewer failures to chase down. Test results reflect how your app behaves, not how the architecture underneath it behaves. Engineers stop spending their mornings separating real failures from environmental ones.

Test the builds you could not test virtually. Apps shipping native ARM64 libraries, including native development kits and ARM-native cryptography, now run on virtual devices at CI concurrency instead of waiting on real device availability.

Catch memory crashes before your users do. Android 15 and 16 move the ecosystem to 16KB memory page sizes. ARM-native execution exposes memory alignment failures in CI, where they cost an hour, rather than in production, where they cost a release.

No disruption to your existing workflow

Android Premium integrates directly into the Sauce Labs platform, working alongside Sauce AI for Insights, Sauce Connect, and live testing. Existing Appium and Espresso configurations work without modification. 

Built for where Android development is heading

ARM64 adoption in Android development is accelerating. On-device AI and native security libraries have moved from edge cases to standard practice, right alongside the graphics-heavy features pushing hardware harder than ever. ARM-native virtual devices in Virtual Device Cloud are built to keep your coverage current as that shift continues. 

It is not a replacement for what already works. It is the path forward for the workloads your current environment was not designed to handle. ARM-native virtual devices for Android are available now in Virtual Device Cloud.
