How to add online server login and SignUP inside android app using HttpURLconnection source code download .This tutorial is one of the most demanded tutorial on internet because every android developer who wish to create a fully dynamic android application is mostly used login and registration feature on their android app with server side code included . So here is the complete step by step tutorial for Android Login Registration With PHP MySQL Example Tutorial Show
 Before getting started things you need to prepare :
List of all activities in this project :
List of all layout files in this project :
List of all PHP files in this project used for server connectivity :
Please follow the steps to import org.apache.http.legacy library in your project :1. Open your project’s build.gradle(Module : App) file . 2. Now type useLibrary ‘org.apache.http.legacy’ inside android scope like i did in below screenshot . Here you Go now this library will be successfully imported in your project . Next step is to start coding . Android Login Registration With PHP MySQL Example Tutorial .Code for MainActivity.java file. package com.android_examples.androidloginregistration_android_examplescom;
