My previous tutorial explains how to download a file by showing a progress bar. In this article I am going to explain how to upload a file to server by showing the progress bar. Using this tutorial you can build an app like Instagram where you can capture image or record a video using camera and then upload to a server. On the server side, I used PHP language to read the file and moved it to a particular location.
The best thing about this article is, it works well with larger file uploads too without any out of memory errors. I have tested the app by uploading 50MB file flawlessly.

Prerequisite
As this article uploads the image/video taken from camera, you need to have knowledge over android camera module. So I recommend you go through my previous tutorial Android Working with Camera which gives you an overview of integrating camera in your android apps.
1. Creating Android Project
1. In Eclipse create a new android project by navigating to File ⇒ New ⇒ Android Application Project and fill out all the required details.
2. Open strings.xml located under res ⇒ values and add below string values.
string.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Camera File Upload</string>
<string name="btnTakePicture">Capture Image</string>
<string name="btnRecordVideo">Record Video</string>
<string name="or">(or)</string>
<string name="btnUploadToServer">Upload to Server</string>
</resources>
3. Add below color values in colors.xml located under res ⇒ values folder.
colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="view_background">#e8ecfa</color>
<color name="btn_bg">#277bec</color>
<color name="white">#ffffff</color>
<color name="txt_font">#4e5572</color>
<color name="action_bar">#1f2649</color>
</resources>
4. Now under src folder create a new class named Config.java. This class file contains file upload URL and image directory name to save the image/video on mobile memory. You will have to replace the file upload url with yours while testing.
Config.java
package net.infotheme.camerafileupload;
public class Config {
// File upload url (replace the ip with your server address)
public static final String FILE_UPLOAD_URL = "http://192.168.0.104/AndroidFileUpload/fileUpload.php";
// Directory name to store captured images and videos
public static final String IMAGE_DIRECTORY_NAME = "Android File Upload";
}
5. Create a class named AndroidMultiPartEntity.java and paste below code. This class is a custom MultipartEntity class which provides very important functionality required for this project such as progress bar incrementation.
AndroidMultiPartEntity.java
package net.infotheme.camerafileupload;
import java.io.FilterOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.nio.charset.Charset;
import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
@SuppressWarnings("deprecation")
public class AndroidMultiPartEntity extends MultipartEntity
{
private final ProgressListener listener;
public AndroidMultiPartEntity(final ProgressListener listener) {
super();
this.listener = listener;
}
public AndroidMultiPartEntity(final HttpMultipartMode mode,
final ProgressListener listener) {
super(mode);
this.listener = listener;
}
public AndroidMultiPartEntity(HttpMultipartMode mode, final String boundary,
final Charset charset, final ProgressListener listener) {
super(mode, boundary, charset);
this.listener = listener;
}
@Override
public void writeTo(final OutputStream outstream) throws IOException {
super.writeTo(new CountingOutputStream(outstream, this.listener));
}
public static interface ProgressListener {
void transferred(long num);
}
public static class CountingOutputStream extends FilterOutputStream {
private final ProgressListener listener;
private long transferred;
public CountingOutputStream(final OutputStream out,
final ProgressListener listener) {
super(out);
this.listener = listener;
this.transferred = 0;
}
public void write(byte[] b, int off, int len) throws IOException {
out.write(b, off, len);
this.transferred += len;
this.listener.transferred(this.transferred);
}
public void write(int b) throws IOException {
out.write(b);
this.transferred++;
this.listener.transferred(this.transferred);
}
}
}
Now we’ll add camera support in our app by creating a simple screen with two buttons to invoke camera app to capture image or record video.
6. Open your AndroidManifest.xml file and add required permissions. You can notice that UploadActivity also added in below manifest file. We’ll create it in few minutes.
INTERNET – Required to make network calls
WRITE_EXTERNAL_STORAGE – Required to store image/video on to storage
RECORD_AUDIO – Required to record audio along with video
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.infotheme.camerafileupload"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="net.infotheme.camerafileupload.MainActivity"
android:label="@string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="net.infotheme.camerafileupload.UploadActivity"
android:screenOrientation="portrait" >
</activity>
</application>
</manifest>
7. Open the layout file of your main activity (activity_main.xml) and add below code. This creates a layout with two buttons.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/view_background"
android:baselineAligned="false"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:orientation="vertical" >
<!-- Capture picture button -->
<Button
android:id="@+id/btnCapturePicture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:background="@color/btn_bg"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:text="@string/btnTakePicture"
android:textColor="@color/white" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:gravity="center_horizontal"
android:text="@string/or"
android:textColor="@color/txt_font" />
<!-- Record video button -->
<Button
android:id="@+id/btnRecordVideo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@color/btn_bg"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:text="@string/btnRecordVideo"
android:textColor="@color/white" />
</LinearLayout>
</RelativeLayout>
8. Add below camera related code in your MainActivity.java class. This code is directly taken from this tutorial.
In brief what this activity will do is,
> Camera app will be launched on tapping take picture or record video button.
> Once the image / video is captured, it will be stored on to mobile SDCard.
> Finally UploadActivity will be launched by passing the SDCard path of the media that is captured. The process of uploading will be done in UploadActivity.

i.putExtra("isImage", isImage);
startActivity(i);
}
/**

// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d(TAG, "Oops! Failed create "
+ Config.IMAGE_DIRECTORY_NAME + " directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
Locale.getDefault()).format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "IMG_" + timeStamp + ".jpg");
} else if (type == MEDIA_TYPE_VIDEO) {
mediaFile = new File(mediaStorageDir.getPath() + File.separator
+ "VID_" + timeStamp + ".mp4");
} else {
return null;
}
return mediaFile;
}
}
Now if you run the app, you should see following output.
Once you are able to launch camera and capture images, we can move forward and start creating the upload activity.
9. Create an xml file under res ⇒ layout folder named activity_upload.xml. This layout contains ImageView, VideoView to preview the captured media and a ProgressBar to show uploading progress.
activity_upload.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/view_background"
android:orientation="vertical"
android:padding="10dp" >
<!-- To display picture taken -->
<ImageView
android:id="@+id/imgPreview"
android:layout_width="fill_parent"
android:layout_height="200dp"
android:visibility="gone"
android:layout_marginTop="15dp"/>
<!-- Videoview to preview recorded video -->
<VideoView

android:layout_width="fill_parent"
android:layout_height="400dp"
android:visibility="gone"
android:layout_marginTop="15dp"/>

android:layout_gravity="center_horizontal"
android:layout_marginBottom="15dp"
android:layout_marginTop="15dp"
android:textColor="@color/txt_font"
android:textSize="30dp" />
<ProgressBar
android:id="@+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="20dp"
android:layout_marginBottom="35dp"
android:visibility="gone"/>
<Button
android:id="@+id/btnUpload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="@color/btn_bg"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:text="@string/btnUploadToServer"
android:textColor="@color/white"
android:layout_marginBottom="20dp"/>
</LinearLayout>
10. Create a class named UploadActivity.java and paste below code. In this activity
> The path of captured camera image/video is received from MainActivity and image/video is displayed on the screen for preview purpose.
> UploadFileToServer async method takes care of uploading file to server and updating the Progress Bar.

Until now we are done with android project. Now let’s quickly create the PHP project to receive the file that is being sent from android app. But before that, we need to do small configuration changes to WAMP server.
2. Installing & Configuring WAMP Server
1. Download and install WAMP software. On windows machine, WAMP will be installed at C:\wamp location.
2. Open php.ini and modify below values. By default wamp server allows maximum of 2MB file only to upload. After changing the below values, you can upload the files upto 50MB size.
upload_max_filesize = 50M post_max_size = 50M max_input_time = 300 max_execution_time = 300
3. Now restart the WAMP server.
3. Creating PHP Project
1. Go inside C:\wamp\www and create a folder named AndroidFileUpload. This will be the root directory of our project.
2. Now go into AndroidFileUpload folder and create a folder named uploads to keep all the uploaded files.
3. Create a file named fileUpload.php and paste below content. Below php code takes care of receiving the files from android app and store them in uploads folder. Upon the processing the file, server responds with a JSON message.
fileUpload.php
<?php
// Path to move uploaded files
$target_path = "uploads/";
// array for final json respone
$response = array();
// getting server ip address
$server_ip = gethostbyname(gethostname());
// final file url that is being uploaded
$file_upload_url = 'http://' . $server_ip . '/' . 'AndroidFileUpload' . '/' . $target_path;
if (isset($_FILES['image']['name'])) {
$target_path = $target_path . basename($_FILES['image']['name']);
// reading other post parameters
$email = isset($_POST['email']) ? $_POST['email'] : '';
$website = isset($_POST['website']) ? $_POST['website'] : '';
$response['file_name'] = basename($_FILES['image']['name']);
$response['email'] = $email;
$response['website'] = $website;
try {
// Throws exception incase file is not being moved
if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
// make error flag true
$response['error'] = true;
$response['message'] = 'Could not move the file!';
}
// File successfully uploaded
$response['message'] = 'File uploaded successfully!';
$response['error'] = false;
$response['file_path'] = $file_upload_url . basename($_FILES['image']['name']);
} catch (Exception $e) {
// Exception occurred. Make error flag true
$response['error'] = true;
$response['message'] = $e->getMessage();
}
} else {
// File parameter is missing
$response['error'] = true;
$response['message'] = 'Not received any file!F';
}
// Echo final json response to client
echo json_encode($response);
?>
Below is the sample JSON response if the file is uploaded successfully. You can use error value to verify the upload on android side.
{
"file_name": "DSC_0021.JPG",
"email": "[email protected]",
"website": "www.infotheme.net",
"message": "File uploaded successfully!",
"error": false,
"file_path": "http://192.168.0.104/AndroidFileUpload/uploads/DSC_0021.JPG"
}
4. Testing the File Upload (localhost)
The following steps shows you how to test the both apps together locally.
1. Connect the both the devices (machine running the wamp server & android mobile) to same wifi network.
2. Start the WAMP server.
3. Get the ip address of the machine that is running the PHP project. You can get the ip address by typing ipconfig in command prompt. (On mac os, use ifconfig to get the ip address)
4. Replace the ip address in Config.java (check 4th step in android project) with your ip address.
5. Deploy & run the android app on the mobile.
