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="computer-help-tips.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>
Download main.xml.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;

CPUinfo.setText(ReadCPUinfo());
}
private String ReadCPUinfo()
{

String result="";
try{
String[] args = {"/system/bin/cat", "/proc/cpuinfo"};
