I have developed an app in Java - Eclipse to upload images to google app engine using Google Picker API. While in development mode it works as it should, when i deploy it to Google app engine, the code stops working (as it does in development mode (stops uploading images to drive)).
I have created a Browser key, and I have that key as API key for the app. Also, in allowed referers, i have it as any referer its allowed.
I suspect that i dont have to show any code, as this isnt a coding issue. If it was, it wouldnt be working in dev mode.
Can you help me out?
