Downloading Firebase Storage Files Device Issue

Downloading Firebase Storage Files Device Issue

I assume that the issue here is that the tmp and Documents directories don't actually live at /tmp and /Documents (for instance, it appears as though /Documents is actually /User/Documents, which is actually /private/var/mobile/Documents, see: https://www.theiphonewiki.com/wiki/)

You'll want to make sure you're creating your File URLs based off where the system thinks those directories are, rather than a string:

NSURL *tmpDirURL = [NSURL fileURLWithPath:NSTemporaryDirectory()];
NSURL *fileURL = [[tmpDirURL URLByAppendingPathComponent:@"my_file"] URLByAppendingPathExtension:@"txt"];

Or similar for NSDocumentDirectory. As for why that works on the simulator: I assume this is because sandboxing on the simulator doesn't work the same way as a real device, and that /tmp is apparently a valid location you can write to (though likely not the one you want to be writing two, as evidenced by iOS throwing a hissy fit when you try to do it on a real device).

Error when downloading from Firebase storage

This is not a storage error, it's actually an issue with the file you're attempting to write to.

Looks like URLByAppengingString should be fileURLWithPath to get a file system URL (per NSFileManager creating directory error 518 NSFileWriteUnsupportedSchemeError).

Long term we need to fish this out and serve it as a "see relevant error" rather than "read network response."

Firebase Storage Resource Not Downloading in Flutter App

Your code defines a function called download, but you don't actually invoke that function anywhere.

To execute the code in the download function you defined, add download() right before the closing } of onPressed:

ElevatedButton(
  onPressed: () {
    Future<void> download() async {
      ...
        if (e.code == 'permission-denied') {
          print(
              'User does not have permission to upload to this reference.');
        }
      });
    }
    download(); // br>  },
  child: Text("Track Title")),

Firebase Storage download to local file error

The problem is that at the moment when you write this line:

let downloadTask = imageRef.write(toFile: localURL) { (URL, error) -> Void in
etc.

you don't yet have permission to write to that (localURL) location. To get the permission you need to write the following code before trying to write anything to localURL

let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let localURL = documentsURL.appendingPathComponent("filename")

By doing it you will write the file into the following path on your device (if you are testing on the real device):
file:///var/mobile/Containers/Data/Application/XXXXXXXetc.etc./Documents/filename

If you are testing on the simulator, the path will obviously be somewhere on the computer.

Problem in download Imageuri in Firebase Storage Android

in uploadToFirebase method inside

reference.getDownloadUrl().addOnSuccessListener(uri -> {.....

instead of mImageUri.toString() put uri.toString() as per bellow.So you will get actual url and will solve your problem.

private void uploadToFirebase(Uri mImageUri) {
        if (mImageUri != null) {
            final ProgressDialog progressDialog = new ProgressDialog(getActivity());
            progressDialog.setTitle("Uploading...");
            progressDialog.show();

            StorageReference reference = storageReference.child(System.currentTimeMillis()
                    + "." + getFileExtension(mImageUri));
            reference.putFile(mImageUri)
                    .addOnSuccessListener(taskSnapshot -> {
                        progressDialog.dismiss();
                        Toast.makeText(getActivity(), "Saved Succesfully", Toast.LENGTH_SHORT).show();
                        reference.getDownloadUrl()
                                .addOnSuccessListener(uri -> {
                                    Upload upload = new Upload(uri.toString());
                                    String uploadId = databaseReference.push().getKey();
                                    databaseReference.child(uploadId).setValue(upload);
                                });
                    })
                    .addOnProgressListener(snapshot -> {
                        double progress = (100.0 * snapshot.getBytesTransferred() / snapshot
                                .getTotalByteCount());
                        progressDialog.setMessage("Uploaded " + (int) progress + "%");
                    })
                    .addOnFailureListener(e -> {
                        progressDialog.dismiss();
                        Toast.makeText(getActivity(), "Error Ocurred" + e.getMessage(), Toast.LENGTH_SHORT).show();
                    });

        }
    }

Firebase Storage: Fail to download file even with public access

Try change :

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write:if true
    }
  }
}
