AuthTabCallback

abstract void onExtraCallback(@NonNull String callbackName, @NonNull Bundle args)

Unsupported callbacks that may be provided by the implementation.

Note:Clients should never rely on this callback to be called and/or to have a defined behavior, as it is entirely implementation-defined and not supported.

This can be used by implementations to add extra callbacks, for testing or experimental purposes.

abstract @NonNull Bundle onExtraCallbackWithResult(
    @NonNull String callbackName,
    @NonNull Bundle args
)

The same as onExtraCallback, except that this method allows the Auth Tab provider to return a result. A return value of EMPTY will be used to signify that the client does not know how to handle the callback. As optional best practices, KEY_SUCCESS could be use to identify that callback was *successfully* handled. For example, when returning a message with result:

    Bundle result = new Bundle();
    result.putString("message", message);
    if (success)
        result.putBoolean(CustomTabsService#KEY_SUCCESS, true);
    return result;

    Bundle result = extraCallbackWithResult(callbackName, args);
    if (result.getBoolean(CustomTabsService#KEY_SUCCESS)) {
        // callback was successfully handled
    }

abstract void onNavigationEvent(int navigationEvent, @NonNull Bundle extras)

To be called when a navigation event happens.

abstract void onWarmupCompleted(@NonNull Bundle extras)

Called when the browser process finished warming up initiated by warmup.
