DefaultProviderPolicy

A watch face may wish to try and set one or more non-system data sources as the default data source for a complication. If a complication data source can't be used for some reason -- such as when it isn't installed or it doesn't support the requested type -- then the next one is tried. A system complication data source acts as a final fallback in case no non-system data sources can be used.

If the DefaultComplicationDataSourcePolicy is empty, then no default is set.

Introduced in Wear OS 4.

Syntax

<DefaultProviderPolicy defaultSystemProvider="string" defaultSystemProviderType="string" />
