Samsung Galaxy s4 in Eclipse ADT

Question

I want to test my App in a Samsung Galaxy S4, i've checked "unknown sources" and enabled the developer menu and checked "Debug mode". But It is displayed offline

C:\Program Files (x86)\Android\android-sdk\platform-tools>adb.exe devices
List of devices attached
XXXXXXXX        offline

any ideas why?

Solution 1

Check that you have latest Android SDK tools. After installing latest SDK tools, check your phone: you need to confirm that you allow debugging from your computer.

Solution 2

For me, it wasn't until I updated my computer's drivers with Samsung's official driver that I could get my S4 to be recognized in Eclipse (also, don't forget to enable Debugging mode)
