Determining the ARM Processor Version on Your Android Device

Determining the ARM Processor Version on Your Android Device

22 April 2024 Stephan Petzl Leave a comment Tech-Help

When working with Android devices, developers may need to know the specific ARM processor version that a device is using. This can be important for a variety of reasons, such as ensuring compatibility with certain applications or optimizing performance for a particular CPU architecture. Below, we outline methods to help you identify the ARM processor version of your Android device.

Using ADB to Find the ARM Processor Version

Android Debug Bridge (ADB) is a versatile command-line tool that lets you communicate with a device. The ADB command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device.

Method 1: Querying CPU ABI Property

This method retrieves the CPU ABI (Application Binary Interface) property, which indicates the processor architecture.

            adb shell getprop ro.product.cpu.abi

Executing this command will return the ABI type, which corresponds to the processor architecture.

Method 2: Accessing Processor Information via CPU Info

If you require more detailed information about the device’s processor, you can access the /proc/cpuinfo file:

            adb shell cat /proc/cpuinfo

This command will display comprehensive information about the CPU, including the ARM version and other processor details.

Method 3: Listing All Supported ABIs

Sometimes, a device may support multiple ABIs. To list all ABIs that the device supports, use:

            adb shell getprop ro.product.cpu.abilist

This command will return a comma-separated list of supported ABIs.

Understanding the ABI Types

Once you have the ABI type, you can match it to the corresponding architecture:

  • x86 – 32-bit x86 architecture
  • x86_64 – 64-bit x86 architecture
  • armeabi-v7a – 32-bit ARM architecture
  • arm64-v8a – 64-bit ARM architecture

For additional reference and understanding of Android ABIs, you can consult the Android ABIs guide.

Integrating ARM Processor Version Detection into Automated Testing

Identifying the ARM processor version can be a valuable step in automated testing. In scenarios where you need to ensure your application is tested on the correct CPU architecture, integrating this step into your testing workflow is essential.

Our product, Repeato, is a no-code test automation tool that excels in creating, running, and maintaining automated tests for iOS and Android apps. Repeato’s ability to rapidly edit and run tests, combined with its use of computer vision and AI, makes it an ideal solution for testing across various processor architectures.

With Repeato, you can easily incorporate processor version checks into your automated testing process. The tool’s built-in ADB functionality allows you to execute relevant ADB commands directly within your test scripts. This means you can tailor your tests to run on devices with specific ARM versions, ensuring that your app performs optimally on the intended hardware.

Whether you’re working with native frameworks like React Native, Flutter, Unity, or others, Repeato’s flexibility and comprehensive testing capabilities can help you maintain high-quality standards for your mobile applications across different devices and CPU architectures.
