Hello,

You could search the forum for `transparent activity` and show that activity with a transparent background and a panel containing your button and text field or try to open a message box from the transparent activity itself

Hi, what i realy need is a usb sticky service (without any layaut) to send and receive data into a string between usb sticky service and a app.
Any idea?

Thanks

Not sure that I understand the question. Use a service for this. You can make is a sticky service if you like.
