Firebase存储显示错误（未知来源）？

Question

我正在尝试通过将其链接到Firebase存储来关联我的应用

FirebaseStorage storage = FirebaseStorage.getInstance();
    StorageReference storageRef = storage.getReferenceFromUrl("gs://fir-example-c4312.appspot.com");

但是当我打开它和此日志时，它会崩溃

这是我的火力发源地

compile 'com.google.firebase:firebase-storage:9.2.1+'

firebase存储的规则已经成立，数据库实时工作没有问题。
