TrustedWebActivityServiceWrapper

open class TrustedWebActivityServiceWrapper
kotlin.Any
   ↳ androidx.browser.trusted.TrustedWebActivityServiceWrapper

TrustedWebActivityServiceWrapper is used by a Trusted Web Activity provider to wrap calls to the TrustedWebActivityService in the client app. All of these calls except getComponentName() forward over IPC to corresponding calls on TrustedWebActivityService, eg getSmallIconId() forwards to TrustedWebActivityService#getSmallIconId().

These IPC calls are synchronous, though the TrustedWebActivityService method may hit the disk. Therefore it is recommended to call them on a background thread (without StrictMode).
