Public methods

getCapabilities

Added in 1.0.0
@ProtoLayoutExperimental
public @Nullable DeviceParametersBuilders.Capabilities getCapabilities()

Gets renderer supported Capabilities.

getDevicePlatform

Added in 1.0.0
public int getDevicePlatform()

Gets the platform of the device.

getFontScale

Added in 1.0.0
public @FloatRange(from = 0.0, fromInclusive = false, toInclusive = false) float getFontScale()

Gets current user preference for the scaling factor for fonts displayed on the display. This value is used to get from SP to DP (dp = sp * font_scale).

getRendererSchemaVersion

Added in 1.0.0
public @NonNull VersionBuilders.VersionInfo getRendererSchemaVersion()

Gets the maximum schema version supported by the current renderer. When building a layout that uses features not available on schema version 1.0 , this can be used to conditionally choose which feature to use.

getScreenDensity

Added in 1.0.0
public @FloatRange(from = 0.0, fromInclusive = false, toInclusive = false) float getScreenDensity()

Gets density of the display. This value is the scaling factor to get from DP to Pixels (px = dp * density).

getScreenHeightDp

Added in 1.0.0
public @Dimension(unit = 0) int getScreenHeightDp()

Gets height of the device's screen in DP.

getScreenShape

Added in 1.0.0
public int getScreenShape()

Gets the shape of the device's screen.

getScreenWidthDp

Added in 1.0.0
public @Dimension(unit = 0) int getScreenWidthDp()

Gets width of the device's screen in DP.

toString

public @NonNull String toString()
