API call to get processor architecture

Question

As part of my app I\'m using the NDK and was wondering if it\'s worth bundling x86 and mips binaries alongside the standard ARM binaries.

I figured the best way woul

Answer 1

Try this command:

adb shell getprop ro.product.cpu.abi

It tells whether cpu is ARM or Intel , 64 or 86_64

Answer 2

You can use adb command

adb shell getprop ro.product.cpu.abi adb shell getprop ro.product.cpu.abi2

and refer the [site]: How to know a process of an app is 32-bit or 64-bit programmatically in Android lollipop?

If you're looking for the Lollipop API

import android.os.Build;

Log.i(TAG, "CPU_ABI : " + Build.CPU_ABI);
Log.i(TAG, "CPU_ABI2 : " + Build.CPU_ABI2);
Log.i(TAG, "OS.ARCH : " + System.getProperty("os.arch"));

Log.i(TAG, "SUPPORTED_ABIS : " + Arrays.toString(Build.SUPPORTED_ABIS));
Log.i(TAG, "SUPPORTED_32_BIT_ABIS : " + Arrays.toString(Build.SUPPORTED_32_BIT_ABIS));
Log.i(TAG, "SUPPORTED_64_BIT_ABIS : " + Arrays.toString(Build.SUPPORTED_64_BIT_ABIS));

Answer 3

You can use the Build class:

import android.os.Build;

and then read:

Build.CPU_ABI

Answer 4

The values you are looking for are

ro.product.cpu.abi

and

ro.product.cpu.abi2

These can be got using internal api SystemProperties.get So you will have to use Reflection on SystemProperties.

You could use the function getSystemProperty if you are not too keen on reflection. Check it here

Answer 5

My Code looks like this

private String cpuinfo()
{
String arch = System.getProperty("os.arch");    
String arc = arch.substring(0, 3).toUpperCase();
String rarc="";
if (arc.equals("ARM")) {
    rarc= "This is ARM";
    }else if (arc.equals("MIP")){
        rarc= "This is MIPS";
    }else if (arc.equals("X86")){
        rarc= "This is X86";
    }
    return rarc;
}

Answer 6

You can also use android SDK, take a look on the Build class:

    /** The name of the instruction set (CPU type + ABI convention) of native code. */
    public static final String CPU_ABI = getString("ro.product.cpu.abi");

    /** The name of the second instruction set (CPU type + ABI convention) of native code. */
    public static final String CPU_ABI2 = getString("ro.product.cpu.abi2");
