Upload image to server from Android – Apache

I developed an application for upload image from Android on XAMPP server with PHP file. In Android the application runs perfect and image appears as uploaded and no errors appears but when I enter the server there is nothing. Here is my Android code and my PHP code:

AndroidManifest.xml
