Control VLC Player using Android (Wifi Connected)

    My first application of Android comes here.In my first tutorial on Controlling VLC using JAVA you can see that the VLC provides a Web interface from which it can be controlled and it also accepts certain commands.So that can be used to control the media player in Local Area Network using any programming language.This time its Android

Code:
MainActivity.Java

package com.example.first_app;
import java.net.Authenticator;
import java.net.URL;


import android.os.Build;
import android.os.Bundle;
import android.os.StrictMode;

4 Channel relay board using L293D

         Many time it requires controlling relays to automate different things in projects.But thing is generally Relays are driven by either high voltage and requires high current but most of the embedded systems works at lower voltage and the constrain is they cant provide high current.
