我正在使用 FirebaseRemoteConfig 类的单例实例，它是使用以下 Provider 方法生成的。

@Provides
@Singleton
FirebaseRemoteConfig provideFirebaseRemoteConfig() {
    final FirebaseRemoteConfig mFirebaseRemoteConfig = FirebaseRemoteConfig.getInstance();
    FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings.Builder()
            .setDeveloperModeEnabled(BuildConfig.DEBUG)
            .build();
    mFirebaseRemoteConfig.setConfigSettings(configSettings);
    mFirebaseRemoteConfig.setDefaults(R.xml.remote_config_defaults);

    if (mFirebaseRemoteConfig.getInfo().getConfigSettings().isDeveloperModeEnabled()) {
        cacheExpiration = 0;
    }

    mFirebaseRemoteConfig.fetch(cacheExpiration)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if (task.isSuccessful()) {
                        // Once the config is successfully fetched it must be activated before newly fetched
                        // values are returned.
                        mFirebaseRemoteConfig.activateFetched();
                    } else {
                        FirebaseCrash.log("RemoteConfig fetch …
