Langkah awal dalam tutorial yaitu membuat database dengan nama volley_upload dengan nama tabel volley_upload dan struktur tabelnya seperti berikut :

Column name	Data Type	lenght	Primary Key	Not Null	Auto Increment
id	int	10	v	v	v
name	varchar	50
photo	text

Membuat web service untuk parsing data aplikasi android.
koneksi.php
Sebagai koneksi aplikasi ke database. Coding-nya disini.
upload.php
Untuk upload gambar ke sever dan menyimpan data di database. Coding-nya disini.
Buat project baru di Android Studio File ⇒ New Project. Kemudian pilih Blank Activity dan melanjutkannya hingga selesai.

activity_main.xml
Layout container untuk floating action button.

</LinearLayout>

Buka build.gradle dan tambahkan volley library didalamnya.

compile 'com.mcxiaoke.volley:library:1.0.19'

build.gradle

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.android.support:design:23.2.0'
    compile 'com.mcxiaoke.volley:library:1.0.19'
}

Agar project terstruktur dan terorganisir, buat 2 paket dengan nama app dan volley. Untuk membuat paket baru , klik kanan pada src=>New=>Peckage dan memberikan nama paket. Contoh : com.dedykuncoro.uploadimage.

Buat class dengan nama LruBitmapCache.java didalam package volley dan tambah coding seperti dibawah ini. Class ini berfungsi untuk mengatur caching network image dalam penyimpanan.
LruBitmapCache.java

package com.dedykuncoro.uploadimage.volley;

import android.graphics.Bitmap;
import android.support.v4.util.LruCache;

import com.android.volley.toolbox.ImageLoader.ImageCache;

public class LruBitmapCache extends LruCache<String, Bitmap> implements
		ImageCache {
	public static int getDefaultLruCacheSize() {
		final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
		final int cacheSize = maxMemory / 8;

		return cacheSize;
	}

	public LruBitmapCache() {
		this(getDefaultLruCacheSize());
	}

	public LruBitmapCache(int sizeInKiloBytes) {
		super(sizeInKiloBytes);
	}

	@Override
	protected int sizeOf(String key, Bitmap value) {
		return value.getRowBytes() * value.getHeight() / 1024;
	}

	@Override
	public Bitmap getBitmap(String url) {
		return get(url);
	}

	@Override
	public void putBitmap(String url, Bitmap bitmap) {
		put(url, bitmap);
	}
}

Buat class AppController.java didalam package app dan tambah coding seperti dibawah ini. Class tunggal yang menginisialisasi class global yang diperlukan. Semua objek yang berhubungan dengan volley diinisialisasi di sini.
AppController.java

package com.dedykuncoro.uploadimage.app;

import android.app.Application;
import android.text.TextUtils;

import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.toolbox.ImageLoader;
import com.android.volley.toolbox.Volley;

import com.dedykuncoro.uploadimage.volley.LruBitmapCache;

public class AppController extends Application {

	public static final String TAG = AppController.class.getSimpleName();

	private RequestQueue mRequestQueue;
	private ImageLoader mImageLoader;
	LruBitmapCache mLruBitmapCache;

	private static AppController mInstance;

	@Override
	public void onCreate() {
		super.onCreate();
		mInstance = this;
	}

	public static synchronized AppController getInstance() {
		return mInstance;
	}

	public RequestQueue getRequestQueue() {
		if (mRequestQueue == null) {
			mRequestQueue = Volley.newRequestQueue(getApplicationContext());
		}

		return mRequestQueue;
	}

	public ImageLoader getImageLoader() {
		getRequestQueue();
		if (mImageLoader == null) {
			getLruBitmapCache();
			mImageLoader = new ImageLoader(this.mRequestQueue, mLruBitmapCache);
		}

		return this.mImageLoader;
	}

	public LruBitmapCache getLruBitmapCache() {
		if (mLruBitmapCache == null)
			mLruBitmapCache = new LruBitmapCache();
		return this.mLruBitmapCache;
	}

	public <T> void addToRequestQueue(Request<T> req, String tag) {
		req.setTag(TextUtils.isEmpty(tag) ? TAG : tag);
		getRequestQueue().add(req);
	}

	public <T> void addToRequestQueue(Request<T> req) {
		req.setTag(TAG);
		getRequestQueue().add(req);
	}

	public void cancelPendingRequests(Object tag) {
		if (mRequestQueue != null) {
			mRequestQueue.cancelAll(tag);
		}
	}
}

Buka class MainActivity.java dan tambahkan coding seperti dibawah ini. Class ini berfungsi untuk meng-upload gambar dan nama ke server.
MainActivity.java

package com.dedykuncoro.uploadimage;

import android.app.ProgressDialog;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.provider.MediaStore;

import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.StringRequest;
import com.dedykuncoro.uploadimage.app.AppController;

import org.json.JSONException;

        buttonUpload.setOnClickListener(new View.OnClickListener(){

                uploadImage();
            }
        });
    }

    public String getStringImage(Bitmap bmp){
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
