I have since few days an issue I never had before. When I want to run my app, the window to choose a device appears but its is empty. I have to unplug and replug my phone at each run in order to get my device in the list. I am becoming crazy !!!
Do you know how to solve this issue ?
I am on a MAc computer and my phone is a Samsung S2.
It finally appeared that I had a hardware problem with the micro-usb connection on my Samsung S2 (unstable connection due to a damaged connection). I brought my device t Samsung to be repaired…and it fixed it !
I heard that some people fixed this problem by updating all the components in Eclipse:
1) “Help” menu => check for updates => update all modules
2) Go to the “Android SDK Manager” (icon with the Android symbol in the Eclipse tool bar) and update all the modules which are not updated
But I repeat, for me, it was an hardware problem: usb connection on Samsung S2 are not very reliable on the ‘long’ term (less than 1 year of dev for me…).
