How can I detect whether an Android device have been connected with an external keyboard?

Question

In my app, I have to detect whether an external keyboard is connected to the device to determine what to show to users.

I know the soft keyboard will not show if an external keyboard is connected on my device, Xoom android 3.1.

How can I know whether an Android device have been connected with an external keyboard through an USB or Bluetooth?

Thanks!

Answer 1

you can find out if a bluetooth keyboard is connected to android device with getResources().getConfiguration().keyboard != Configuration.KEYBOARD_NOKEYS;

if it returns true then bluetooth keyboard is connected, false otherwise.
