I am trying to add an image to the user information in the real time database(firebase) for android. I have uploaded the image on the firebase storage but how will I be able to add the image in the database for that user?
Code Below:
//inside onCreate() method
img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(Intent.ACTION_PICK);
i.setType("image/*");
startActivityForResult(i,request_code);
}
});
Here I am clicking on the imageview, so I will be able to change it and get an image from the gallery.
Here I authenticate the user and send data to the database:
auth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(StudentSignUpActivity.this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
Toast.makeText(getApplicationContext(), "createUserWithEmail:onComplete:" + task.isSuccessful(), Toast.LENGTH_SHORT).show();
progressBar.setVisibility(View.GONE);
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Toast.makeText(getApplicationContext(), "Authentication failed." + task.getException(),
Toast.LENGTH_SHORT).show();
} else {
startActivity(new Intent(StudentSignUpActivity.this, HomeActivity.class));
finish();
}
}
});
mCurrentUser=FirebaseAuth.getInstance().getCurrentUser();
DatabaseReference newStudent=mDatabase.push();
newStudent.child("email").setValue(email);
newStudent.child("password").setValue(password);
newStudent.child("name").setValue(name);
newStudent.child("date").setValue(dates);
newStudent.child("phone").setValue(number);
newStudent.child("uid").setValue(mCurrentUser.getUid());
//outside of onCreate()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==request_code&&resultCode==RESULT_OK){
Uri uri=data.getData();
StorageReference filepath=mStorage.child("Images").child(uri.getLastPathSegment());
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
}
});
}
}
In the above code I have uploaded the image to the firebase storage. Now how will i be able to add that image as a child for a specific user.
I think I need to do something like this:
newStudent.child("image").setValue(uri_here);
But I am unable to figure how to get the uri of the image and how to add that uri in the setValue() since its in another method.
You can use the method getDownloadUrl() in the success listener to access the download URL:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==request_code&&resultCode==RESULT_OK){
Uri uri=data.getData();
StorageReference filepath=mStorage.child("Images").child(uri.getLastPathSegment());
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadUrl = taskSnapshot.getDownloadUrl();
newStudent.child("image").setValue(downloadUrl);
}
});
}
}
As an aside, instead of using push(), I recommend storing the user's data with the uid as the key. This will make your data easier to find.
private DatabaseReference newStudent;
mCurrentUser=FirebaseAuth.getInstance().getCurrentUser();
newStudent=mDatabase.child(mCurrentUser.getUid());
newStudent.child("email").setValue(email);
// etc
Just to update because I spent sometime to find this answer, getDownloadUrl() is NOT a function of taskSnapshot anymore. So in order to get the image URL from Firebase Storage you need to add a listener to
taskSnapshot.getMetadata().getReference().getDownloadUrl()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==request_code&&resultCode==RESULT_OK){
Uri uri=data.getData();
StorageReference filepath=mStorage.child("Images").child(uri.getLastPathSegment());
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
taskSnapshot.getMetadata().getReference().getDownloadUrl()
.addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
newStudent.child("image").setValue(uri);
}
});
}
});
}
}
Now it's safe to use uri to whatever you want

I am using the following method to save information.
private void saveUserData() {
progressDialog.setTitle("Account Settings");
progressDialog.setMessage("Please wait while settings are being changed...");
progressDialog.show();
final StorageReference imageRef = storageReference
.child(FirebaseAuth.getInstance().getCurrentUser().getUid());
imageRef.putFile(imageUri);
}
I have removed some lines of code for accessing the database.
This the log cat description.
E/StorageException: StorageException has occurred.
An unknown error occurred, please check the HTTP result code and inner exception for server response.
Code: -13000 HttpResult: 0
E/AndroidRuntime: FATAL EXCEPTION: FirebaseStorage-Upload-1
I seached this error code and found
case unknown = -13000
The app doesn't crash when I comment this line.
imageRef.putFile(imageUri);
On a side note, I am able to save text info successfully and even retrieve it from the database.
EDIT
Here is the code.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
storageReference = FirebaseStorage.getInstance()
.getReference().child("Profile Pictures");
profileImageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, galleryPick);
}
});
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
saveUserData();
}
});
retrieveUserInformation();
}
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == galleryPick && resultCode == RESULT_OK && data != null) {
imageUri = data.getData();
profileImageView.setImageURI(imageUri);
}
}
Given the variable name imageUri, you're trying to upload to Storage from a URL, which is not supported. You'll first have to download the data from the URL, and then upload it to Storage.
floatingActionButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("video/*");
intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), RC_PHOTO_PICKER);
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
// Get a reference to store file at chat_photos/<FILENAME>
StorageReference photoRef = mChatPhotosStorageReference.child(selectedImageUri.getLastPathSegment());
// Upload file to Firebase Storage
photoRef.putFile(selectedImageUri)
.addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// When the image has successfully uploaded, we get its download URL
// progressBar.setVisibility(View.VISIBLE);
Uri downloadUrl = taskSnapshot.getDownloadUrl();
// Set the download URL to the message box, so that the user can send it to the database
Video video = new Video(downloadUrl.toString());
mMessagesDatabaseReference.push().setValue(video);
}
});
}
}
I want to show progress on seekbar when image is uploading as a notification. How do I do that? I have created an object of Seekbar in my onCreate. How to get duration of the video which I am uploading and show the seekbar in notification and the user should not be able to swipe notification when upload starts? Please help.
you can do that by using addOnProgressListener
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
int progress = (int) ((100 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount());
try {
yourSeekBar.setProgress(progress);
} catch (Exception e) {
e.printStackTrace();
}
}
})
I have not use authentication yet, in the screen i can see the progress dialog working but its not getting stop. I think there is a problem.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==GALLERY_INTENT&&resultCode==RESULT_OK){
progressDialog.setMessage("Uploading Image...");
progressDialog.show();
Uri uri = data.getData();
StorageReference filepath = mStorageRef;
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(Profile.this, "Uploading Finished",Toast.LENGTH_LONG).show();
}
});
}
}
//firebase storage rule
service firebase.storage {
match /b/csapplication-b6e5e.appspot.com/o {
match /{allPaths=**} {
allow read, write: if request.auth == null;
}
}
}
Its because of if your file upload to firebase was successful means your ProgressDialog will be dismissed ,if not in the case of failure you have to dismiss (ProgressDialog) in the OnFailure method in the code below .
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(Profile.this, "Uploading Finished",Toast.LENGTH_LONG).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads - Dismiss the ProgressDialog here
progressDialog.dismiss();
Toast.makeText(Profile.this, "Unable to Uploaded Error in Firebase",Toast.LENGTH_LONG).show();
}});
Can you please help me, I am trying to upload an image in FirebaseStorage.
But it fails.
My Button click Method
public void uploadImage(View view){
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent,GALLERY_INTENT);
}
And here is onActivityResult()
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
progressDialog.setMessage("Uploading");
progressDialog.show();
if(requestCode ==GALLERY_INTENT){
final Uri uri = data.getData();
StorageReference filepath = storageReference.child("Photos").child(uri.getLastPathSegment());
filepath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(getApplicationContext(),"Uploaded Successfully",Toast.LENGTH_LONG).show();
// profileImage.setImageURI(uri);
progressDialog.dismiss();
}
});
}
}
What's wrong with this code?
Try this
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.e("resultCode: ", resultCode + " RequestCode: " + requestCode);
if (resultCode == getActivity().RESULT_OK) {
sendImageToFireBase(data.getData());
}
}
private void saveImageToFireBase(Uri pathUri) {
StorageReference storageReference = FirebaseStorage.getInstance().getReference().child("Photos");
StorageReference photoRef = storageReference.child(pathUri.getLastPathSegment());
// Upload file to Firebase Storage
photoRef.putFile(pathUri).addOnSuccessListener(getActivity(), new OnSuccessListener<UploadTask.TaskSnapshot>() {
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// When the image has successfully uploaded, we get its download URL
Uri downloadUrl = taskSnapshot.getDownloadUrl();
// Set the download URL to the message box, so that the user can send it to the database
}
});
}
Does Google's Firebase support video storage ? Am planning to upload video and want to download on-demand. I started with Firebase. Are there any other APIs or services that give a similar functionality ?
Of course you can upload video or any files on firebase.
btnupload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myIntent = new Intent(Intent.ACTION_GET_CONTENT);
myIntent.setType("*/*");
startActivityForResult(Intent.createChooser(myIntent,"Select File:-"),101);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if(resultCode==RESULT_CANCELED)
{
// action cancelled
}
if(resultCode==RESULT_OK)
{
// Create a storage reference from our app
StorageReference storageRef = storage.getReferenceFromUrl("gs://<<Your App Bucket Address>>");
Uri uri = data.getData();
StorageReference riversRef = storageRef.child("files/"+uri.getLastPathSegment());
UploadTask uploadTask = riversRef.putFile(uri);
// 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
Toast.makeText(MainActivity.this, "Upload Failed", Toast.LENGTH_SHORT).show();
}
}).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.
Toast.makeText(MainActivity.this, "Upload Success", Toast.LENGTH_SHORT).show();
}
});
}
}
Firebase has a Firebase Storage offering that allows you to store any arbitrary files.
It doesn't offer any video-specific features or functionality, but it will work if you simply want to have a place to store and retrieve your video files.
