Hello everyone,
I have shown two methods to upload files in android.
In today’s tutorial I will show another simple method to upload files. With this method you can upload multiple files in one request + you can send your own string parameters with them.
Here is another method on working with uploading of images.
How to upload an image from Android device to server? – Method 4
These are the things to do after creating the project.
1. You have to include two libraries in the your project build path(Download these libraries from here apache-mime4j-0.6.jar and httpmime-4.0.1.jar).
2. Add these libraries to the project build path.
3. Here you can see the the other things you need to remember while connecting to a server.
Refer the image
Note : I am working here on the local system as server. So I have used the server domain name as 10.0.2.2. Please change this according to your need.
OK Now open your main java file and copy this code into it.

Now the layout for this file main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Multiple File Upload from CoderzHeaven"
/>
<Button
android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get First File">
</Button>
<Button
android:id="@+id/Button02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get Second File">
</Button>
<Button
android:id="@+id/upload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start Upload">
</Button>
<TextView
android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Selected File path : "
/>
<TextView
android:id="@+id/res"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""
/>
</LinearLayout>
Now the AndroidManifest file(Remember to add the permission for accessing internet)
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="pack.coderzheaven"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET" />
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".FileUploadTest"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Now the server side(Here it is written in PHP)
upload_media_test.php file contents
<?php
$target_path1 = "uploads/";
$target_path2 = "uploads/";
/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path1 = $target_path1 . basename( $_FILES['uploadedfile1']['name']);
if(move_uploaded_file($_FILES['uploadedfile1']['tmp_name'], $target_path1)) {
echo "The first file ". basename( $_FILES['uploadedfile1']['name']).
" has been uploaded.";
} else{
echo "There was an error uploading the file, please try again!";
echo "filename: " . basename( $_FILES['uploadedfile1']['name']);
echo "target_path: " .$target_path1;
}
$target_path2 = $target_path2 . basename( $_FILES['uploadedfile2']['name']);
if(move_uploaded_file($_FILES['uploadedfile2']['tmp_name'], $target_path2)) {
echo "n The second file ". basename( $_FILES['uploadedfile2']['name']).
" has been uploaded.";
} else{
echo "There was an error uploading the file, please try again!";
echo "filename: " . basename( $_FILES['uploadedfile2']['name']);
echo "target_path2: " .$target_path2;
}
$user = $_REQUEST['user'];
echo "n String Parameter send from client side : " . $user;
?>
