How to upload the Multipart Request data on server Using Android Volley.
Creating New Project.
Open android studio and create a new project.
File => New => New Project => Configure your new project => Select the form factor yours app will run on => Add an Activity to Mobile => Customize the Activity => Finish.
First we need to add Library to our project.
compile 'dev.dworks.libs:volleyplus:+'
Create Xml file in project.
Open => app => res => layout - 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:padding="16dp"
tools:context="org.snowcorp.imageupload.MainActivity"
android:orientation="vertical">
<Button
android:id="@+id/button_choose"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="SelectImage"
android:textColor="#000"
android:layout_gravity="center_horizontal"
android:layout_margin="20dp"
android:padding="10dp"/>
<ImageView
android:id="@+id/imageView"
android:layout_width="200dp"
android:layout_height="200dp"
android:background="@drawable/border"
android:layout_gravity="center_horizontal"
android:padding="5dp"
android:layout_margin="20dp"/>
<Button
android:id="@+id/button_upload"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Post"
android:textColor="#000"
android:layout_gravity="center_horizontal"
android:layout_margin="20dp"/>
</LinearLayout>
