How to upload an image to Firebase storage?

Question

I'm trying to upload a simple byte array into Firebase storage, but my onFailureListener keeps getting called and logging back to me saying that the upload failed. I'm hoping you guys can tell me whats wrong with my code.

At the top I got

 //Firebase private Firebase mRef; private StorageReference storageRef;

Then in onStart()

@Override protected void onStart() { super.onStart(); googleApiClient.connect(); //Firebase mRef = new Firebase("link to firebase account"); FirebaseStorage storage = FirebaseStorage.getInstance(); storageRef = storage.getReferenceFromUrl("link to storage"); }

Then in my onActivityResult()

 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { addImageImageView.setVisibility(View.GONE); if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK && data != null) { //First we gotta make sure to add the images to ArrayList<Image> imagesFromGallery = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES); for (int i = 0; i < imagesFromGallery.size(); i++) { try { //try uploading it InputStream stream = new FileInputStream(new File(imagesFromGallery.get(i).path)); StorageReference imageStorage = storageRef.child("cardImages/" + "testImages"); UploadTask uploadTask = imageStorage.putStream(stream); uploadTask.addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { Log.d("myStorage","failure :("); } }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { Log.d("myStorage","success!"); } }); catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (FileNotFoundException e) { e.printStackTrace(); } } }

Here is my stack trace:

In onFailure(), add e.getMessage() to the log message to see the reason for the exception. — Bob Snyder

The documentation explains that the default security rules for Firebase Storage require authentication. Have you signed-in the user or changed the rules to allow public access? — Bob Snyder

You either need to sign-in the user or change the security rules to allow public access. This is explained in the documentation for Firebase Storage Security.

For initial development, you can change the rules at the Firebase Console to allow public access:

service firebase.storage { match /b/project-XXXXXXXXXXXXXX.appspot.com/o { match /{allPaths=**} { // Provide access to all users allow read: if true; allow write: if true; } } }

You wrote : "... match /b/project-XXXXXXXXXXXXXX.appspot.com/o {...". Must I put in the project package name or project's so called Public-facing name. Mine is project-xxxxxxxx?
@CodeToLife: It looks like things have changed since I wrote this answer. Originally, the Project ID (shown on General tab of Project Settings) was used. Now it looks like you can use {bucket}. See the sample rules for an example.

I upload images using this code :

private void uploadFile(Bitmap bitmap) { FirebaseStorage storage = FirebaseStorage.getInstance(); StorageReference storageRef = storage.getReferenceFromUrl("Your url for storage"); StorageReference mountainImagesRef = storageRef.child("images/" + chat_id + Utils.getCurrentTimeStamp() + ".jpg"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos); byte[] data = baos.toByteArray(); UploadTask uploadTask = mountainImagesRef.putBytes(data); 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, and download URL. Uri downloadUrl = taskSnapshot.getDownloadUrl(); sendMsg("" + downloadUrl, 2); Log.d("downloadUrl-->", "" + downloadUrl); } }); }

Dependency :

Project Level Gradel : classpath 'com.google.gms:google-services:3.0.0'

App Level Gradel : compile 'com.google.firebase:firebase-storage:9.0.2'

do you know if, in app gradle we need to include anything for firebase storage?
In project level gradel we have require to classpath 'com.google.gms:google-services:3.0.0' and app level gradel we have require compile 'com.google.firebase:firebase-storage:9.0.2' define

Simply call this method to store your image to firebase.

 private void storeImageToFirebase() { BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 8; // shrink it down otherwise we will use stupid amounts of memory Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoUri.getPath(), options); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos); byte[] bytes = baos.toByteArray(); String base64Image = Base64.encodeToString(bytes, Base64.DEFAULT); //For the API less than 28 (Android version 8 ) //String base64Image = android.util.Base64.encodeToString(bytes, android.util.Base64.DEFAULT); // we finally have our base64 string version of the image, save it. firebase.child("pic").setValue(base64Image); System.out.println("Stored image with length: " + bytes.length); }

For more details see these examples:

dont you need Upload task and StorageReference to put it in firebase storage?

this method worked for me as if todate:

private void uploadImage(Bitmap bitmap) { progressDialog.show(); final StorageReference ref = storageReference.child("drivers/" + UserDto.getId() + ".jpg"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos); byte[] data = baos.toByteArray(); final UploadTask uploadTask = ref.putBytes(data); uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { progressDialog.dismiss(); Toast.makeText(ProfileActivity.this, "Uploaded", Toast.LENGTH_SHORT).show(); uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() { @Override public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception { if (!task.isSuccessful()) { throw task.getException(); } return ref.getDownloadUrl(); } }).addOnCompleteListener(new OnCompleteListener<Uri>() { @Override public void onComplete(@NonNull Task<Uri> task) { if (task.isSuccessful()) { Uri downUri = task.getResult(); Log.d("Final URL", "onComplete: Url: " + downUri.toString()); } } }); } }).addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { progressDialog.dismiss(); Toast.makeText(ProfileActivity.this, "Failed " + e.getMessage(), Toast.LENGTH_SHORT).show(); } }); }

Upload multilple images to Firebase storage.

It is working for me.

using this library

 compile 'com.github.darsh2:MultipleImageSelect:3474549'

At the top

private StorageReference storageRef; private FirebaseApp app; private FirebaseStorage storage;

onCreate()

app = FirebaseApp.getInstance(); storage =FirebaseStorage.getInstance(app);

button click action

 Gallary.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(ChatActivity.this, AlbumSelectActivity.class); intent.putExtra(Constants.INTENT_EXTRA_LIMIT, 10); startActivityForResult(intent, Constants.REQUEST_CODE); } });

Activity result

public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == Constants.REQUEST_CODE && resultCode == RESULT_OK) { ArrayList<Image> images = data.getParcelableArrayListExtra(Constants.INTENT_EXTRA_IMAGES); Uri[] uri=new Uri[images.size()]; for (int i =0 ; i < images.size(); i++) { uri[i] = Uri.parse("file://"+images.get(i).path); StorageReference ref = storage.getReference("photos").child(uri[i].getLastPathSegment()); ref.putFile(uri[i]) .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { @Override public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { Uri downloadUrl = taskSnapshot.getDownloadUrl(); String content = downloadUrl.toString(); } }) .addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception exception) { } }) .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() { @Override public void onProgress(UploadTask.TaskSnapshot taskSnapshot) { //displaying the upload progress double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount(); progressDialog.setMessage("Uploaded " + ((int) progress) + "%..."); } }); } } }

@Nizamudeen Sherif i will send to the source code. Please give your mail id
