How to Upload a Pdf to a Server

Our this tutorial Android Upload PDF File to Server is very accelerate tutorial for android developers because we have uploading PDF file direct to online website hosting server by using PHP script. Later on sending the file directly to sever we would receive that file using POST method and store that file on a folder created on domain server. Nosotros would also store the complete uploaded PDF path URL into MySQL database. So it could exist accessed for some farther usages.

Contents in this project Android Upload PDF File to Server Using PHP MySQL :

1. Spotter the live demo video.
2. Start a new android application development project in Studio.
3. Create Database with Tabular array on server.
4. Create PDF storage folder on server.
5. Create PHP Script to receive PDF file coming from awarding.
6. Addingnet.gotev:uploadservice:2.one library in your project.
7. Calculation Internet and READ_EXTERNAL_STORAGE permission to AndroidManifest.xml file.
8. Create Two buttons and one EditText in layout file.
9. Starting time Coding.

Listing of Java files in this project :

• MainActivity.coffee .
• FilePath.java .

Listing of Layout file in this projection :

• activity_main.xml .

List of PHP file in this projection :

• file_upload.php .

1. Watch the live demo video :

2. Get-go a new android awarding development project in Studio.

3. Create Database with Table on server :

Create Database on your hosting or local sever and within that database create a tabular array named equally " PdfTable ". Inside that table create 3 columns id, PdfURL, PdfName . Screenshot of tabular array is given below.

4. Create PDF storage folder on server :

My testing domain proper noun isandroidblog.esy.es . I am creating a folder inside my domain hosting storage and inside that folder my PDF uploading folder present. My PDF uploading binder path ishttp://androidblog.esy.es/AndroidJSon/PdfUploadFolder/ . So merely create same binder with same name on your server.

5. Create PHP Script to receive PDF file coming from application :

Next step is to create the PHP scripting file which URL we would call from application and this file would store PDF on server.
Code for file_upload.php file.

<?php   ServerConfig();  $PdfUploadFolder = 'PdfUploadFolder/';   $ServerURL = 'http://androidblog.esy.es/AndroidJSon/'.$PdfUploadFolder;   if($_SERVER['REQUEST_METHOD']=='POST'){    if(isset($_POST['proper name']) and isset($_FILES['pdf']['name'])){   $con = mysqli_connect(HostName,HostUser,HostPass,DatabaseName);    $PdfName = $_POST['name'];    $PdfInfo = pathinfo($_FILES['pdf']['name']);    $PdfFileExtension = $PdfInfo['extension'];    $PdfFileURL = $ServerURL . GenerateFileNameUsingID() . '.' . $PdfFileExtension;    $PdfFileFinalPath = $PdfUploadFolder . GenerateFileNameUsingID() . '.'. $PdfFileExtension;    try{    move_uploaded_file($_FILES['pdf']['tmp_name'],$PdfFileFinalPath);    $InsertTableSQLQuery = "INSERT INTO PdfTable (PdfURL, PdfName) VALUES ('$PdfFileURL', '$PdfName') ;";   mysqli_query($con,$InsertTableSQLQuery);   }grab(Exception $e){}   mysqli_close($con);    } }  function ServerConfig(){   define('HostName','mysql.hostinger.in'); define('HostUser','u288012116_json'); define('HostPass','N1c45hlf'); ascertain('DatabaseName','u288012116_json');   }  office GenerateFileNameUsingID(){    $con2 = mysqli_connect(HostName,HostUser,HostPass,DatabaseName);    $GenerateFileSQL = "SELECT max(id) as id FROM PdfTable";    $Holder = mysqli_fetch_array(mysqli_query($con2,$GenerateFileSQL));   mysqli_close($con2);    if($Holder['id']==null)  {  return 1;  }  else  {  return ++$Holder['id'];  } }  ?>

six. Adding net.gotev:uploadservice:2.1 library in your project :

ane. Open your projection'sbuild.gradle(Module:app) file.

2. Add compile 'internet.gotev:uploadservice:ii.ane' independencies scope .

7. Adding Internet and READ_EXTERNAL_STORAGE permission to AndroidManifest.xml file :

Open your project'due south AndroidManifest.xml file and add beneath both permission inside it. Y'all could observe the complete AndroidManifest.xml file source code at the end of this page.

 <uses-permission android:name="android.permission.Internet"/>  <uses-permission android:proper name="android.permission.READ_EXTERNAL_STORAGE"/>

 8. Create Two buttons and one EditText in layout file :

<EditText     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:inputType="textPersonName"     android:hint="Enter PDF Name"     android:ems="10"     android:gravity="center"     android:layout_centerVertical="truthful"     android:layout_centerHorizontal="true"     android:id="@+id/editText" />  <Button     android:text="Upload pdf on online server"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_marginTop="54dp"     android:id="@+id/button2"     android:layout_below="@+id/editText"     android:layout_alignParentStart="true" />  <Button     android:text="Select PDF TO Upload"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:id="@+id/button"     android:layout_above="@+id/editText"     android:layout_alignParentStart="true"     android:layout_marginBottom="62dp" />

 9. Start Coding for project Android Upload PDF File to Server :
