I am building an android app which allows users to upload pictures to firebase storage. I am still in development mode so I set up my storage rules to public. When the user selects a picture to upload, the file is not uploaded but the download URL is returned. Logcat shows the following error
E/StorageUtil: error getting token java.util.concurrent.ExecutionException: com.google.firebase.internal.api.FirebaseNoSignedInUserException: Please sign in before trying to get a token.
And here is my storage rules
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}
And my android java code:
private void uploadPic() {
StorageReference mStorageRef = FirebaseStorage.getInstance().getReference();
Uri fileUrl = Uri.fromFile(new File(filePath));
String fileExt = MimeTypeMap.getFileExtensionFromUrl(fileUrl.toString());
final String fileName = UUID.randomUUID().toString()+"."+fileExt;
StorageReference profilePicsRef = mStorageRef.child("profile_pics/"+fileName);
profilePicsRef.putFile(fileUrl)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// Get a URL to the uploaded content
Uri downloadUrl = taskSnapshot.getDownloadUrl();
Log.d("DOWNLOAD_URL", downloadUrl.toString());
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads
// ...
Toast.makeText(getApplicationContext(), "Error: "+exception.toString(), Toast.LENGTH_LONG).show();
}
});
}
Any help will be greatly appreciated.
UPDATE
I have narrowed down the problem: I have two folders in storage, I can upload to the "Videos" folder, but not to the "profile_pics" folder or any other folder. Why is this happening?
For some reason unknown to mere mortals, the gods have refused upload to any folder that starts with "profile". I had to create another folder "users_profile_pic". Three days wasted!

I would like to upload my SQLite database File to Firebase Storage. My problem is that I can only find tutorials where the user has to choose the file manually, but I would like to send a fixed file, so you can't send other data to Firebase storage.
How can I do that?
Thank you.
First get the reference to the firebase storage
// Create a storage reference from our app
StorageReference storageRef = storage.getReference();
Then to upload the file do the following:
Uri file = Uri.fromFile("sqlite_file");
StorageReference filesRef = storageRef.child("files");
uploadTask = filesRef.putFile(file);
// Register observers to listen for when the download is done or if it fails
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// taskSnapshot.getMetadata() contains file metadata such as size, content-type, etc.
// ...
}
});
I have uploaded some files into Firebase directory and I want to list them and download one by one.There is no API/Documentation fo this.Could you help me ?
As of July 2019, version 18.1.0 of the Cloud Storage SDK now supports listing all objects from a bucket. You simply need to call listAll() in a StorageReference:
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
// Now we get the references of these images
storageRef.listAll().addOnSuccessListener(new OnSuccessListener<ListResult>() {
#Override
public void onSuccess(ListResult result) {
for(StorageReference fileRef : result.getItems()) {
// TODO: Download the file using its reference (fileRef)
}
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(Exception exception) {
// Handle any errors
}
});
If you want to download these files, you can use one of the options shown in the Docs.
Please note that in order to use this method, you must opt-in to version 2 of Security Rules, which can be done by making rules_version = '2'; the first line of your security rules:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
first , you should get the file download Url to retrieve it, the easiest way is to upload a file and generate the download Url in your database, so after that you just go and retrieve each file from the storage like this :
private void downloadFile() {
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReferenceFromUrl("<your_bucket>");
StorageReference islandRef = storageRef.child("file.txt");
File rootPath = new File(Environment.getExternalStorageDirectory(), "file_name");
if(!rootPath.exists()) {
rootPath.mkdirs();
}
final File localFile = new File(rootPath,"imageName.txt");
islandRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
Log.e("firebase ",";local tem file created created " +localFile.toString());
// updateDb(timestamp,localFile.toString(),position);
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
Log.e("firebase ",";local tem file not created created " +exception.toString());
}
});
}
I personally use this method, whenever you upload a file, save its download URL in your Firebase Database, if you are uploading multiple files then save it in an array. There is no method for Firebase Storage android to download and upload multiple files in one go.
Whenever you want to download files access your firebase database for those URL's.
I'm developing a simple Android application that downloads a file from Firebase storage.
Is there any way to download a file getting only a link to the file? I found a few methods but they were requiring also the name of file
I don't know the name of downloading file, I need to download the file knowing only its URL.
Just try this :
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference httpsReference = storage.getReferenceFromUrl("YOUR_FIREBASE_STORAGE_URL");
File localFile = File.createTempFile("PREFIX_FILE", "SUFFIX_FILE");
httpsReference.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
// Local temp file has been created
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle any errors
}
});
Firebase Storage documentation.
I am trying to download a pdf file using Firebase. Whenever I click the item which should initiate the download, the download fails.
And I get this message in the log monitor:-
StorageException has occurred. User does not have permission to access this object. Code: -13021 HttpResult: 403
My read/write permission in the Firebase console looks like this:-
service firebase.storage {
match /b/savephoto-a1cc3.appspot.com/o {
match /{allPaths=**} {
// Allow access by all users
allow read, write;
}
}
}
Also my java code for downloading the file looks like this
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReference();
StorageReference islandRef = storageRef.child("CSD-101").child("Midsems").child("2016").child("CSD101_MidSem.pdf");
File rootPath = new File(Environment.getExternalStorageDirectory(), "Question Papers");
if(!rootPath.exists()) {
rootPath.mkdirs();
}
final File localFile = new File(rootPath,"CSD-101 Midsems.pdf");
islandRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
#Override
public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(Year2.this, "File Downloaded", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(Year2.this, "Download Failed", Toast.LENGTH_SHORT).show();
}
});
What can I do?
you should update your firebase console rules with this code
{ "rules": {
".read": true,
".write": true}}
I am trying to upload a picture via a local file method.
UploadTask uploadTask = currentPicRef.putFile(file, metadata);
When the user pick's image from the gallery or taking a picture via the camera the picture is saved in external storage and I save the uri in shared preference.
I successfully loaded the image into an imageview using the setImageURI(uri) method, but When I call the firebase method and using the same uri (Uri file = Uri.fromFile(new File(fileName));)
I get the error
could not locate file for uploading:file:///content%3A/media/external/images/media/22943
but when I use log to check the local file I get
uri is content://media/external/images/media/22943
also worth to mention that when I used uri.parse() instead uri.fromFile() in firebase to upload from a local file it uploaded the metadata but not the photo itself.
Any ideas how to fix it?
Maybe it's a bit late, anyway:
could not locate file for uploading:file:///content%3A/media/external/images/media/22943
I think you may have a problem of url encoding (see %3A in the file uri).
Try to decode the uri Uri file = Uri.fromFile(new File(fileName)); before passing it to Firebase Storage Reference.
If it does not work, instead retrieving the image uri in this way Uri.fromFile(new File(fileName)) , you can try to save the local image path in the shared preferences (I'm supposing that when you get the image from gallery or camera, you can have also the local path), and use this to upload the image in the storage Firebase.
Hope can help.
fileName can be determined fileUri.toString(). This worked for me:
Uri uploadUri = Uri.fromFile(new File(fileUri.toString()));
Here's an example that works:
// [START upload_from_uri]
private void uploadFromUri(Uri fileUri) {
Uri uploadUri = Uri.fromFile(new File(fileUri.toString()));
Log.d(TAG, "uploadFromUri:src:" + fileUri.toString());
// [START get_child_ref]
// Get a reference to store file at photos/<FILENAME>.jpg
final StorageReference photoRef = mStorageRef.child("photos").child(uploadUri.getLastPathSegment());
// [END get_child_ref]
// Upload file to Firebase Storage
// [START_EXCLUDE]
showProgressDialog();
// [END_EXCLUDE]
Log.d(TAG, "uploadFromUri:dst:" + photoRef.getPath());
photoRef.putFile(uploadUri)
.addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// Upload succeeded
Log.d(TAG, "uploadFromUri:onSuccess");
// Get the public download URL
mDownloadUrl = taskSnapshot.getMetadata().getDownloadUrl();
// [START_EXCLUDE]
hideProgressDialog();
updateUI(mAuth.getCurrentUser());
// [END_EXCLUDE]
}
})
.addOnFailureListener(this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Upload failed
Log.w(TAG, "uploadFromUri:onFailure", exception);
mDownloadUrl = null;
// [START_EXCLUDE]
hideProgressDialog();
Toast.makeText(MainActivity.this, "Error: upload failed",
Toast.LENGTH_SHORT).show();
updateUI(mAuth.getCurrentUser());
// [END_EXCLUDE]
}
});
}
// [END upload_from_uri]
