Which of the following statements is false?
a. Android devices have various screen sizes, resolutions and pixel densities (that is, dots per inch or DPI), so you typically provide images in various resolutions that the operating system chooses based on a device’s pixel density. These are placed in drawable folders (in a project’s res folder) that store images with different pixel densities.
b. Android Studio displays only one drawable folder containing the app’s drawa-ble resources, even if your project contains resources for multiple densities.
c. If Android cannot find an image in the drawable folder that most closely matches the device’s pixel density, Android will display nothing for that image.
d. Low-resolution images do not scale well. For images to render nicely, a high-pixel-density device needs higher-resolution images than a low-pixel-density device.
c. If Android cannot find an image in the drawable folder that most closely matches the device’s pixel density, Android will display nothing for that image. Actually, if Android cannot find an image in the drawable folder that most closely matches the device’s pixel density, Android will scale the version from another drawable folder up or down as necessary.
