Android Upload Image to Server Using Volley

Here you will learn about android upload image to server using volley library.

At server side I have used java web service and for sending image to server volley library is used.

How it works?

• The user chooses an image from gallery and click on upload button.
• The image is then converted into Base64 string format and sent to server using volley network library.
• Now at server side this Bas64 string is converted back into image and stored at some location.

Server Code

Below is the code for server. It is a java web service. If you don’t know how to make web service in java then read below tutorial.

DemoService.java

package example;

import java.io.FileOutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.FormParam;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.apache.commons.codec.binary.Base64;

@Path("/DemoService")
public class DemoService {
	@POST
	@Path("/upload")
	@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
	@Produces(MediaType.TEXT_HTML)
	public String uploadImage(@FormParam("image") String image) {
		String result="false";
		
		//decode Base64 String to image
		try{
			FileOutputStream fos = new FileOutputStream("H:/image.jpg"); //change the path where you want to save the image
			byte byteArray[] = Base64.decodeBase64(image);
			fos.write(byteArray);
			 
			result="true";
			fos.close();		
		}
		catch(Exception e){
			e.printStackTrace();
		}
		
		return result;
	}
}

Android Project

1. Now create a new android project with package name com.androiduploadimage

2. Add dependency for volley library by adding following line in build.gradle file.

compile 'com.android.volley:volley:1.0.0'

3. Add internet access permission in AndroidManifest.xml file.

<uses-permission android:name="android.permission.INTERNET"/>

4. Add following code in respective files.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="15dp"
    android:paddingLeft="15dp"
    android:paddingRight="15dp"
    android:paddingTop="15dp"
    tools:context="com.androiduploadimage.MainActivity"
    android:orientation="vertical">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:id="@+id/image"/>

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Choose"
        android:id="@+id/choose"/>

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Upload"
        android:id="@+id/upload"/>

</LinearLayout>
