How to get Memory usage and CPU usage in android?
<p>Is there any API by which we can get CPU or Memory usage of android?</p>

<p>I have tried one code as below:</p>

<p>Please look into it and let me know if this is the correct way?</p>

<pre><code>package com.infostretch.mainactivity;

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;


public class CPULoad 
{
    long total = 0;
    long idle = 0;


float usage = 0;

public CPULoad( )
{
    readUsage( );
}

public float getUsage( )
{
    readUsage( );
    return usage;
}

private void readUsage( )
{
    try
    {
        BufferedReader reader = new BufferedReader( new InputStreamReader( new FileInputStream( "/proc/stat" ) ), 1000 );
        String load = reader.readLine();
        reader.close();     

        String[] toks = load.split(" ");

        long currTotal = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[4]);
        long currIdle = Long.parseLong(toks[5]);

        this.usage = (currTotal - total) * 100.0f / (currTotal - total + currIdle - idle);
        this.total = currTotal;
        this.idle = currIdle;
    }
    catch( IOException ex )
    {
        ex.printStackTrace();           
    }
}
}
</code></pre>

<p>I will be very thankful for your anykind of help.</p>
