TokenStore

Kotlin |Java

public interface TokenStore

androidx.browser.trusted.TokenStore

Users should implement this interface to persist the given Token (across app restarts). Once implemented, they should override TrustedWebActivityService.getTokenStore() to return an instance. Finally, they should execute the following code themselves to set the verified provider:

 TokenStore tokenStore  = ... // Instantiate the implemented class.
 String packageName = ... // Package name of the Trusted Web Activity provider.

 tokenStore.store(Token.create(packageName, getPackageManager());

There is only a single Token stored at a time. Note that load() will be called by TrustedWebActivityService on a binder thread. Whereas store(Token) can be called by the user on whichever thread they like.
