Question

To detect screen orientation, you can create a values directory that uses the ________________ or ________________ qualifiers.

Answer 1

In Android app development, screen orientation can be detected by creating values directories with 'orientation' or 'screen size' qualifiers, allowing for different resources to apply for landscape or portrait modes and various screen sizes.

Step-by-step explanation:

To detect screen orientation, you can create a values directory that uses the orientation or screen size qualifiers. When designing Android apps, developers can specify different resources for different orientations (portrait or landscape) and screen sizes by creating different values directories within the app's 'res' folder. For instance, you might have a 'values-land' directory for landscape orientation and a 'values-port' directory for portrait orientation. Similarly, you can have 'values-large' for large screens or 'values-sw600dp' for screens with at least 600 dp of width. These directories contain XML files where you can define various values such as string resources, dimensions, and styles, which the Android system will automatically apply based on the current device orientation or screen size.
