General :: App To Run Ping Commands

Building an app that runs a ping command at the moment and I can't quite get it to work. If I modify the command to something that isn't a terminal command then it'll output my error statement but i can't get it to display the ping output. I know my outputs for my error are bad but it's an easy way to determine what path it's outputting.

package com.mycompany.myapp;

import android.app.*;
import android.os.*;
import android.view.*;
import android.widget.*;
