Question

I am building an app that needs to know whether the device is in landscape or portrait mode. So I figured, I will use onCreate, I know that is called on device rotation. But onCreate is call only once!! When I rotate the device, nothing happens. I am debugging on an actual device, Motorola Xoom, so I am NOT using the emulator. Someone had this kind of problem?

Answer 1

Check if int the Manifest file you declare

android:configChanges=”orientation”

if you declared this flag, the activity will not be destroyed and recreated and the callback

onConfigurationChanged()

will be called.
