'No active compatible AVD's or devices found

Question

I'm new with Eclipse ADT, and I tried to run an app on my tablet (a Samsung Galaxy Note 10.1), but there is an error as below:

[2013-12-26 12:37:41 - SDK_Example] ------------------------------

[2013-12-26 12:37:41 - SDK_Example] Android Launch!

[2013-12-26 12:37:41 - SDK_Example] adb is running normally.

[2013-12-26 12:37:41 - SDK_Example] Performing com.metaio.Example.MainActivity activity launch

[2013-12-26 12:37:41 - SDK_Example] No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD.

Can anyone tell me why my device isn't found?

Answer 1

So if you are using emulator then close it.
In Eclipse select Run > Run Configurations > Target > Always prompt to pick device > Run.
Now select a a device from the list or a launch a new emulator. The next time you Run the project it should work.

Answer 2

Seems like your device is not getting detected by the ADB.

Check if you have enabled USB debugging in your tablet or not. Sometimes disconnecting and re-connecting the device also makes it work. Also bear in mind that the API level of your application should be supported by your device.
