Android Get Processor Model

Getting Processor Model on Android

Determining the processor model of an Android device is essential for various tasks, such as optimizing performance, understanding device capabilities, and identifying specific features. This article provides a comprehensive guide on retrieving the processor model information using different approaches.

Methods to Retrieve Processor Model

1. Using Build.CPU_ABI

The Build.CPU_ABI property provides information about the CPU architecture supported by the device. While it doesn’t directly give the processor model, it helps identify the general CPU family.

Code Example:

import android.os.Build;

String cpuAbi = Build.CPU_ABI;
System.out.println("CPU ABI: " + cpuAbi); 

Output:
CPU ABI: armeabi-v7a

Possible values for Build.CPU_ABI include:

• armeabi-v7a
• arm64-v8a
• x86
• x86_64

2. Using System Properties

Android provides a mechanism to access system properties, which can reveal processor-related information. The "ro.product.cpu.abi" property often contains details about the CPU model.

Code Example:

import android.os.Build;

String cpuModel = System.getProperty("ro.product.cpu.abi");
System.out.println("CPU Model: " + cpuModel);

Output:
CPU Model: armeabi-v7a

3. Using CPU-Z App

The popular CPU-Z app offers a user-friendly interface to access comprehensive device hardware information, including processor model, cores, clock speed, and cache details. This approach is ideal for visual presentation and ease of use.

4. Using System Files

Advanced users can examine system files, such as /proc/cpuinfo, to retrieve detailed processor information. This approach requires root access.

import java.io.BufferedReader;
import java.io.InputStreamReader;

// Requires root access
Process process = Runtime.getRuntime().exec("cat /proc/cpuinfo");

BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));

String line;
while ((line = reader.readLine()) != null) {
    if (line.startsWith("Hardware")) {
        System.out.println("CPU Model: " + line.split(":")[1].trim());
        break;
    }
}

Output:
CPU Model:  ARMv7 Processor rev 5 (v7l)
