Uploading and Downloading of files – Popular and Useful posts from CoderzHeaven

In one of the previous posts I have shown one method to upload an image in android.
Here is another method to upload a media file like images,audio or video in android.
Here is the main java file that does the upload.
Here I am trying to open audio from the gallery. However you can change it to image or video according to your need.
The code for upload will not change since we change only the code for opening the gallery. We use only the path of the selected file whether it is image or video or audio to upload.

These are for downloading files from the server.

1. How to Download an image in ANDROID programatically?
2. How to download a file to your android device from a remote server with a custom progressbar showing progress?

         // close streams
         Log.e("Debug","File is written");
        catch (MalformedURLException ex)
             Log.e("Debug", "error: " + ex.getMessage(), ex);
        catch (IOException ioe)
             Log.e("Debug", "error: " + ioe.getMessage(), ioe);
        //------------------ read the SERVER RESPONSE
        try {
              inStream = new DataInputStream ( conn.getInputStream() );
              String str;

              while (( str = inStream.readLine()) != null)
                   Log.e("Debug","Server Response "+str);

        catch (IOException ioex){
             Log.e("Debug", "error: " + ioex.getMessage(), ioex);

Now the server side , the code is written in Php.

// Where the file is going to be placed
$target_path = "uploads/";

/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
    echo "filename: " .  basename( $_FILES['uploadedfile']['name']);
    echo "target_path: " .$target_path;

Things to keep in mind
1. Make sure your server is running.
2. Your server file path should be right.
3. Check your folder write permission in the server.
