Read Android CPU info

Android CPU info. can be retrieved by reading of "/proc/cpuinfo". So, it's just a very little bit of modification on Read Android OS version.



Create a new Android Application, with the Activity named AndroidCPUinfoActivity. Modify the main.xml and AndroidCPUinfoActivity.java:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 >
<TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:gravity="center_horizontal"
 android:text="android-er.blogspot.com"
 android:autoLink="web"
 />
<TextView
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:text="Android CPU Info.:"
 />
<TextView
 android:id="@+id/CPUinfo"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 />
</LinearLayout>

AndroidCPUinfoActivity.java

package com.exercise.AndroidCPUinfo;

import java.io.IOException;
import java.io.InputStream;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class AndroidCPUinfoActivity extends Activity {
 /** Called when the activity is first created. */
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
  
     TextView CPUinfo = (TextView) findViewById(R.id.CPUinfo);
     CPUinfo.setText(ReadCPUinfo());
  
 }

 private String ReadCPUinfo()
 {
  ProcessBuilder cmd;
  String result="";
  
  try{
   String[] args = {"/system/bin/cat", "/proc/cpuinfo"};
   cmd = new ProcessBuilder(args);
   
   Process process = cmd.start();
   InputStream in = process.getInputStream();
   byte[] re = new byte[1024];
   while(in.read(re) != -1){
    System.out.println(new String(re));
    result = result + new String(re);
   }
   in.close();
  } catch(IOException ex){
   ex.printStackTrace();
  }
  return result;
 }
}
