Android Select Image from Gallery Upload to Server example tutorial using JSON

How to send image along with Text using JSON PHP and store image path in MySQL database.

In this tutorial we are going to upload image on server using AsyncTask and doInBackground task. Sending image to server is very much typical for all the android developers so in this tutorial we are going to create an android application which will upload the selected image online directly to server. We will using PHP script to get and sending image and storing that image to folder and store the image name with its complete path into MySQL database. So here is the complete step by step tutorial for Android Select Image from Gallery Upload to Server example tutorial.

What we are doing in this project :

We are creating a folder named as “images” on our online web hosting server and after that we will create a MySQL database and inside that database we will create a table named as “ImageUpload”. There are three Fields inside that table id, image_data and image_tag . After that we will create android code which will send the selected image to server.
