Different orientations on smartphone and tablet

Question

Hello, I am developing an app and I need the screen to be in Portrait for smartphones and Portrait/Landscape for tablets. The customer does not want to accept different applications and does not want to leave the orientation unlocked on the smartphone. My solution was to create a bool that changes the value according to the screen size, but the application closes on the smartphone when starting it when the device is in Landscape. The main class extends the Norotatescreen class, the code within it is:

   boolean tabletSize = getResources().getBoolean(R.bool.isTablet);
   if (!tabletSize) {
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
   }

The file that arrow the Boolean file is like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="isTablet">true</bool>
</resources>

What can I do?

Answer 1

Create a layout in the folder layout-large or in the layout-xlarge, use the same layout you use for the mobile (same name), but will change the id of some piece. then in the code you do something like:

        // tablet
        if (findViewById(R.id.menu) != null) {
            // esse id.menu só vai existir no layout com tablet
        } else {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }

Use this method to know if the device is tablet:

public static boolean isTabletDevice(final Context ct) {
        if (android.os.Build.VERSION.SDK_INT >= 11) { // honeycomb
            /**
             * testa o tamanho da tela usando reflection porque isLayoutSizeAtLeast
             * só está disponível a partir do skd int 11
             */
            Configuration con = ct.getResources().getConfiguration();
            try {
                Method mIsLayoutSizeAtLeast = con.getClass().getMethod(
                        "isLayoutSizeAtLeast", int.class);
                Boolean r = (Boolean) mIsLayoutSizeAtLeast.invoke(con,
                        0x00000004); // Configuration.SCREENLAYOUT_SIZE_XLARGE
                return r;
            } catch (Exception x) {
                return false;
            }
        }
        return false;
    }
