Android Volley Tutorial

Goal

Connect to MySQL database and operate on Android phones

My Tools

• LAMP Server + phpMyAdmin

  • [For Ubuntu] http://it-easy.tw/ubuntu-lamp/

• Android Studio 2.1

Volley

• HTTP client library published by Goolgle

• Improved some old ways like:

  • HttpClient : was removed at Android 6.0
  • HttpURLConnection : need to use and handle the thread

• Provides three requests for loading data:

  • StringRequest
  • JsonObjectRequest
  • ImageRequest

• Provides Cache for improving performance

  • However, in a large of data transmission, the performance of volley is very bad
