android - Firebase 存储 - StorageReference.getFile() 在设备离线时崩溃

Question

当我尝试使用方法 StorageReference.getFile(File) 从 Firebase 存储下载文件时当设备离线并达到超时时，它会崩溃。 Logcat 在 DynamicModulesC 中显示 NPE:

java.lang.NullPointerException: null reference
at asn.a(:com.google.android.gms.DynamiteModulesC:27)                                                                                     

相同的代码可以正常工作，并且可以在互联网连接可用时下载文件。我已经在装有 Android 4.1 和 6.0 的设备和模拟器上对其进行了测试。 Firebase SDK 版本 9.6.1。这是 firebase SDK 中的错误吗？我错过了什么吗？

代码简单:

FirebaseStorage firebaseStorage = FirebaseStorage.getInstance();
//firebaseStorage.setMaxDownloadRetryTimeMillis(15 * 1000);
StorageReference remoteDir= firebaseStorage.getReference().child("dir-with-files");
File destinationFile= new File("file-in-app-internal-storage");
StorageReference fileRef = remoteDir.child("file-from-firebase");
fileRef.getFile(destinationFile);

事实证明这是 Google Play 服务中的一个错误。 Firebase 团队已经修复了它。 Google Play 服务 9.8.77 版提供了此修复程序。

现在 StorageReference.getFile(File) 不会在设备离线时使应用程序崩溃。相反，您将收到以下回复:

E/StorageException: StorageException has occurred. 
The operation retry limit has been exceeded. 
Code: -13030 HttpResult: -2
