java - 尝试将图像保存到 Firebase 存储时，我在 android studio 中遇到错误
问题描述
我正在制作一个 android 应用程序，该应用程序的一部分正在为用户保存显示图像。下面的代码块是将图像保存在 Firebase 存储中的方法。我已经在 firebase 中配置了规则，并在清单文件中设置了访问图像的权限。在用户选择图库中的图像后调用该方法。选择图像有效，但保存部分无效。我已经做了很多方法来解决这个问题，但似乎没有任何效果。代码中似乎存在 IDE 无法检测到的错误。错误在运行时。用户在图库中选择图像后，应用程序将关闭。
mStorage 已经在 onCreate 方法中初始化。选择的图像保存在 uriProfileImage 中。uploadProgress 只是一个进度条。
private void uploadImageToFirebaseStorage() {
mStorage = FirebaseStorage.getInstance().getReference();
StorageReference profileImageRef = mStorage.child("displayImages/" + System.currentTimeMillis() + uriProfileImage.getPath().substring(uriProfileImage.getPath().lastIndexOf(".")));
uploadProgress.setVisibility(View.VISIBLE);
if (uriProfileImage != null) {
profileImageRef.putFile(uriProfileImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
uploadProgress.setVisibility(View.GONE);
profileImageUrl = taskSnapshot.getDownloadUrl().toString();
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
uploadProgress.setVisibility(View.GONE);
Toast.makeText(getActivity(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
我得到这个错误

请帮我。我已经尝试了很多方法来解决它，但我根本没有取得任何进展。
解决方案
我找到了解决方案。我发布这个是为了帮助其他有同样问题的人。
问题是我提供的 StorageReference 是错误的。
我把它从
mStorage = FirebaseStorage.getInstance().getReference();
StorageReference profileImageRef = mStorage.child("displayImages/" + System.currentTimeMillis() + uriProfileImage.getPath().substring(uriProfileImage.getPath().lastIndexOf(".")));
至
StorageReference profileImageRef = FirebaseStorage.getInstance().getReference("displayImages/"+System.currentTimeMillis()+".jpg");
似乎以前的 StorageReference 返回了无效的存储引用。我还更新了我的 firebase 存储和数据库依赖项。
另一件事是上面用于获取已上传图片的 downloadUrl 的代码不起作用。
所以我把它从
profileImageUrl = taskSnapshot.getDownloadUrl().toString();
至
profileImageUrl = taskSnapshot.getMetadata().getReference().getDownloadUrl().toString();
我希望这有帮助。
