Android does not recognize screen sizes

Question

I am developing an android application which needs to have different layouts for tablet in landscape and other screen sizes. I've created different layouts in different folders like it is suggested in android tutorial (http://developer.android.com/training/multiscreen/screensizes.html).

So I have layout-xlarge, layout-xlarge-land and so on and layout preview seems to recognize those layouts for different devices however when I launch my application, the layouts are no longer recognized as per device. Following code always returns normal size layout:

int screenLayout = context.getResources().getConfiguration().screenLayout;
        screenLayout &= Configuration.SCREENLAYOUT_SIZE_MASK;

switch (screenLayout) {
       case Configuration.SCREENLAYOUT_SIZE_XLARGE:
          initXLargeLayout();
          return;
       default:
          initViePagerDefaultLayout();
          return;
    }

I could not find anyone with similar problem. Should I add something to manifest file?

I think, instead of using your int screenLayout you should do something like that: https://stackoverflow.com/a/9308284/4907293

That might be because you're launching on a device that does not have an xlarge screen, so it goes into your default. What device are you using?

By the way, you don't have to do that switch-case code because Android detects the configuration for you and selects from your layout folders (xlarge, mdpi, etc) and uses the appropriate layout automatically.

Your folder structure should look like this:

res
├── layout
│   └── activity_main.xml
├── layout-xlarge
|   └── activity_main.xml
└── layout-xlarge-land
    └── activity_main.xml

You just have to do setContentView(R.layout.activity_main.xml) once in your code and Android will take care of choosing which of those to use, depending on the device.

I suggest find out what configuration your device is, maybe it's just a large or some other size.
