How to Check Android ARM Version?

Published in Android ARM 2 mins read

You can check the Android ARM version by using specific commands in a terminal environment on your device.

Checking the ARM architecture version on an Android device helps developers and users understand the hardware capabilities, which is crucial for installing compatible applications and optimizing performance. The ARM architecture determines the instruction set the processor uses.

Methods to Check ARM Architecture

According to the reference, the process is similar to checking the CPU information on any Linux system. You can use either the uname command or examine the contents of the /proc/cpuinfo file.

Method 1: Using uname -m

The uname command displays system information. The -m flag specifically shows the machine hardware name, which often indicates the architecture.

  • How to use:

    1. Open an ADB shell connected to your device or launch a Terminal Emulator app on your Android device.
    2. Type the command: uname -m
    3. Press Enter.

  • Example Output:

    • aarch64 (Indicates ARM64 architecture)
    • armv7l (Indicates ARMv7 architecture, 32-bit)

Method 2: Using cat /proc/cpuinfo

The /proc/cpuinfo file contains detailed information about the processor(s) in your system. It usually includes the architecture, processor model, and other relevant details.

  • How to use:

    1. Open an ADB shell connected to your device or launch a Terminal Emulator app on your Android device.
    2. Type the command: cat /proc/cpuinfo
    3. Press Enter.

  • Finding the ARM Version: Look for lines that mention "Architecture," "CPU architecture," or "Processor". The information will typically specify the ARM version (e.g., ARMv7, ARMv8).

Executing the Commands

As stated in the reference: "Simply do uname -m or cat /proc/cpuinfo on adb shell or any Terminal emulator app. It's same for any Linux OS, not specific to Android."

  • ADB Shell: Requires a computer with Android Debug Bridge (ADB) installed, connected to the Android device via USB (with USB debugging enabled).
  • Terminal Emulator App: Many free apps are available on the Google Play Store that provide a Linux command-line environment directly on the device.

Using either method in a terminal environment will provide the necessary information about your device's ARM architecture.
