TokenStore

Kotlin |Java

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:

<code>TokenStore tokenStore  = ... // Instantiate the implemented class.
  String packageName = ... // Package name of the Trusted Web Activity provider.
 
  tokenStore.store(Token.create(packageName, getPackageManager());
  </code>

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