Question

Can anyone please tell me if there is any way we can find out if a bluetooth QWERTY keyboard is attached to android device.

I tried working with getResources().getC

Answer 1

One way to do this is adding android:configChanges="keyboard" to the activity in your AndroidManifest.xml file.

With this you can override onConfigurationChanged which will be called whenever a keyboard is plugged in or plugged out

 @Override
 public void onConfigurationChanged(Configuration newConfig) 
 {
   if(newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        //A hardware keyboard is being connected
   }  
   else if(newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES)
       //A hardware keyboard is being disconnected
   }

 }
