I'm working on eclipse in ubuntu, I test my mobile app in my nexus 5... Everything was working fine (USB debugging mode is enabled), until tonight : I see that eclipse won't recognize my android anymore it shows me : "Unknown device ????????", I have changed the target SDK
to 19
since i have android Kitkat 4.4.2, nothing works, then 17
etc...
I have tested the app on another android phone with Android 4.2.1 and it was recognized well.
I find this very strange since I was running the app on my Nexus 5 yesterday and it was working well..
Do you please have any idea about this ? Thank you.
