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
Before getting started things you need to prepare :
- Android Studio .
- Emulator or Your android phone ( To test the app ) .
- Online free hosting server that supports PHP .
- Working internet connection in your mobile phone .
- Just read all the below instructions .
List of all activities in this project :
- MainActivity.java .
- LoginActivity.java .
- Profile .
List of all layout files in this project :
- activity_login.xml .
- activity_main.xml .
- activity_profile.xml .
List of all PHP files in this project used for server connectivity :
- dbconfig.php .
- insert-registration-data.php .
- android-login.php .
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 .
