Public functions

baselineProfile

Added in 8.2.0
@Incubating
fun baselineProfile(action: BaselineProfile.() -> Unit): Unit

Configure baseline profile properties

Public properties

enable

Added in 8.13.0-alpha03
var enable: Boolean

Specifies whether to enable code shrinking and resource optimization. Property works for applications only. For other types it will be ignored

By default, value is false to avoid runtime issue. When enabled the Android plugin uses R8 for optimization.

Flavours merge this property with "or" rule. That means having this enable=true sticks.

packageScope

Added in 8.13.0-alpha03
val packageScope: SetProperty<String>

Specifies what packages are included for optimization. Those may be local code packages and external libraries packages. You can include

  • classes for a single package, like "com.example.app.*"

  • classes from package and all subpackages, like "androidx.**"

  • everything "**"

Default (convention) value is "**"
