I'm trying to run my App on a real hardware phone.
I have the adb installed and I tried to kill-server, then start-server and every time when I write adb devices my device shows up okay.
Then I go to the DDMS in the Eclipse and there also my phone is okay connected and stuff, I can even take screenshot from my display.
But then when I want to run my App, the pop-out (Android Device Chooser) window is empty. There are only Virtual machines there.
I did this on my Windows PC and it worked fine, and I was able to run my App. I reinstalled Eclipse several times, but with no luck.
I had the same experience after upgrading my mac to OS X Yosemite. Try enlarging the serial number column in your Android device chooser. That did the trick for me, since the device was apparently only 'hidden'.
