And the /proc/cpuinfo hold infoprmation about the CPU, you can read it as text file.

Example:

package com.example.androidcpuinfo;

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends ActionBarActivity {

 TextView cores, cpuinfo;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        cores = (TextView)findViewById(R.id.cores);
        cpuinfo = (TextView)findViewById(R.id.cpuinfo);
        
        Runtime runtime = Runtime.getRuntime();
        int availableProcessors = runtime.availableProcessors();
        cores.setText("You have " + availableProcessors + " availableProcessors");
        
        //Read text file "/proc/cpuinfo"
        String file_cpuinfo = "/proc/cpuinfo";
        String info = "";
        try {
   FileReader fileReader = new FileReader(file_cpuinfo);
   BufferedReader bufferReader = new BufferedReader(fileReader);

   String line;
         try {
    while((line = bufferReader.readLine()) != null)
    {
     info += line + "\n";
    }
    cpuinfo.setText(info);
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
         
  } catch (FileNotFoundException e) {
