SplitPinRule.Builder

public Builder()

public final @NonNull SplitPinRule build()

Builds a SplitPinRule instance.

public final @NonNull SplitPinRule.Builder setDefaultSplitAttributes(
    @NonNull SplitAttributes defaultSplitAttributes
)

Sets the default SplitAttributes to apply on the activity containers pair when the host task bounds satisfy minWidthDp, minHeightDp, minSmallestWidthDp, maxAspectRatioInPortrait and maxAspectRatioInLandscape requirements.

public final @NonNull SplitPinRule.Builder setMaxAspectRatioInLandscape(@NonNull EmbeddingAspectRatio aspectRatio)

Sets the largest value of the aspect ratio, expressed as width / height in decimal form, of the parent window bounds in landscape when the split should be used. When the window aspect ratio is greater than requested here, activities in the secondary container will be stacked on top of the activities in the primary one, completely overlapping them.

This value is only used when the parent window is in landscape (width height).

The default is SPLIT_MAX_ASPECT_RATIO_LANDSCAPE_DEFAULT if the app doesn't set, which is the recommend value to always allow split when the parent window is in landscape.

public final @NonNull SplitPinRule.Builder setMaxAspectRatioInPortrait(@NonNull EmbeddingAspectRatio aspectRatio)

Sets the largest value of the aspect ratio, expressed as height / width in decimal form, of the parent window bounds in portrait when the split should be used. When the window aspect ratio is greater than requested here, activities in the secondary container will be stacked on top of the activities in the primary one, completely overlapping them.

This value is only used when the parent window is in portrait (height >= width).

The default is SPLIT_MAX_ASPECT_RATIO_PORTRAIT_DEFAULT if the app doesn't set, which is the recommend value to only allow split when the parent window is not too stretched in portrait.

public final @NonNull SplitPinRule.Builder setMinHeightDp(@IntRange(from = 0) int minHeightDp)

Sets the smallest value of height of the parent task window when the split should be used, in DP. When the window size is smaller than requested here, activities in the secondary container will be stacked on top of the activities in the primary one, completely overlapping them.

It is useful if it's necessary to split the parent window horizontally for this SplitPinRule.

The default is SPLIT_MIN_DIMENSION_DP_DEFAULT if the app doesn't set. SPLIT_MIN_DIMENSION_ALWAYS_ALLOW means to always allow split.

public final @NonNull SplitPinRule.Builder setMinSmallestWidthDp(@IntRange(from = 0) int minSmallestWidthDp)

Sets the smallest value of the smallest possible width of the parent window in any rotation when the split should be used, in DP. When the window size is smaller than requested here, activities in the secondary container will be stacked on top of the activities in the primary one, completely overlapping them.

The default is SPLIT_MIN_DIMENSION_DP_DEFAULT if the app doesn't set. SPLIT_MIN_DIMENSION_ALWAYS_ALLOW means to always allow split.

public final @NonNull SplitPinRule.Builder setMinWidthDp(@IntRange(from = 0) int minWidthDp)

Sets the smallest value of width of the parent window when the split should be used, in DP. When the window size is smaller than requested here, activities in the secondary container will be stacked on top of the activities in the primary one, completely overlapping them.

The default is SPLIT_MIN_DIMENSION_DP_DEFAULT if the app doesn't set. SPLIT_MIN_DIMENSION_ALWAYS_ALLOW means to always allow split.

public final @NonNull SplitPinRule.Builder setSticky(boolean isSticky)

Sets this rule to be sticky.

public final @NonNull SplitPinRule.Builder setTag(String tag)

Sets a unique string to identify this SplitPinRule, which defaults to null. The suggested usage is to set the tag to be able to differentiate between different rules in the SplitAttributesCalculatorParams.splitRuleTag.
