Running app on phone

MattRMattR USMember

I have a galaxy S2 and I did the hell_world. I can see it in the emulator, but cannot see my phone in devices. I followed the tutorial enabling the USB option, etc.

Any help?
Thanks, Matt

    Have you enabled developer mode on the phone?

    Hi Matthew,

    Have you installed the device driver for Samsung Galaxy S2?

    From the Android SDK?

    I can hook my phone up to my laptop and transfer files from phone.
