Fix bug in my webview app, make it work for all phones and android versions above 3.0

Contest Brief In the attachment I have an app. Basically it uses WebView and uploads photo to server. Problem is: it works fine for some android devices and phones however for some android devices and phones FILE UPLOAD does not work. For example click the "Resim Seç" button, take photo, save and click "Gönder" button. And you can test if file upload works or not. If it says "Imaj dosyasi yuklendi!" then it is working. If you can not see this text then it is not working. Make this app work for all android versions above 3.0 and for all phones. Price will be given after test results. First fully working result will be accepted. IMPORTANT: It should work same for all android phones having Android 3.0 and above
