【问题描述】：

我想检查 Firebase 存储中是否存在文件，如果存在则更新其元数据。 OnFailureListener 按预期工作，如下所示：

storageRef.child("users/me/file.png").getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
    @Override
    public void onSuccess(Uri uri) {
        // Got the download URL for 'users/me/profile.png'
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception exception) {
        // File not found
    }
});

但是，我在 logcat 上得到了这个错误跟踪：

2020-05-21 01:45:04.484 10910-11160/pl.edu.mimuw.exshare E/StorageException: StorageException has occurred.

有什么方法可以阻止打印此错误消息？

【解决方案1】：

如果存储 SDK 将某些内容打印到日志中，则您无法更改该行为，只能从 open source 自行构建 SDK，并删除您不想要的日志记录。

或者，您可以忽略日志。或者您可以在 GitHub 上提出问题并要求开发人员将其删除。
