Detecting orientation like in camera app

Question

I am developing application that is somehow similar to camera, I wish that the app will always be in landscape mode witch I achieve with:

android:screenOrientation="portrait"

But I need to know when user rotates the phone to landscape mode so I can rotate the icons 90 degrees.

I have tried:

   if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) 
    {
        Toast.makeText(getApplicationContext(), "ORIENTATION_LANDSCAPE", Toast.LENGTH_SHORT).show();

    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){

        Toast.makeText(getApplicationContext(), "ORIENTATION_PORTRAIT", Toast.LENGTH_SHORT).show();
    }

But it only works when I add:

android:configChanges="keyboardHidden|orientation|screenSize"

And its also change my orientation automatically.

So how can I keep my app always in Landscape mode and only detect when the phone is in Portrait without that phone automatically change anything? Just like in camera app

You can try this by comparing Device width and height, If there is a change you can rotate icons.. — Kanak Sony, Dec 31 '13 at 11:06

Using android:configChanges="keyboardHidden|orientation|screenSize" is a good idea.

Now try setting your orientation manually:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Hi, Thank you but I do not wish to change the orientation, just to know it. – Dim Dec 31 '13 at 10:48
@DanM This is what it does. You will get notification change event, while your orientation will not be changed. – Ilya Gazman Dec 31 '13 at 12:07
Can you give me an example, how to use it in code and how to add listener? – Dim Jan 01 '14 at 07:33
