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.

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


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.
