Store photo in Firebase Storage.
The following should be updated as there was a recent change to Firebase.
implementation 'com.firebaseui:firebase-ui-auth:4.0.0'
// Upload file to Firebase Storage
photoRef.putFile(selectedImageUri);
mChatPhotosStorageReference.putFile(selectedImageUri).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 mChatPhotosStorageReference.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
FriendlyMessage friendlyMessage = new FriendlyMessage(null, mUsername, downloadUri.toString());
mMessagesDatabaseReference.push().setValue(friendlyMessage);
}
}
});
}
@swdevdave As others partners here, I tried your code but, the photo doesn't upload at all and doesn't show up on screen either.
E/Surface: getSlotFromBufferLocked: unknown buffer: 0xb40fc300 Not supplying enough data to HAL, expected position 68787138 , only wrote 68650799
@swdevdave I have also tried your code snippet and it is not working. Do you have any tips? @RRGT19 Were you able to upload the photos? Mine is still not uploading.
@swdevdave and @RRGT19 Never mind about my above comment because I have fixed the bug. One of my if statement was blocking the code from running. Thanks.
Hey guys, I take a look at Firebase documentation and I was able to upload the picture with this code:
} else 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());
UploadTask uploadTask = photoRef.putFile(selectedImageUri);
uploadTask.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.d(TAG,"Unsuccessful upload");
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadUrl = taskSnapshot.getDownloadUrl();
assert downloadUrl != null;
FriendlyMessage friendlyMessage =
new FriendlyMessage(null, mUsername, downloadUrl.toString());
mMessagesDatabaseReference.push().setValue(friendlyMessage);
}
});
}

its not working for me as well for others and still there is no problem looking in code at all ??
Ey, this code works
StorageReference photoRef = mChatPhotosStorageReference.child(selectedImageUri.getLastPathSegment());
photoRef.putFile(selectedImageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
photoRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
FriendlyMessage friendlyMessage = new FriendlyMessage(mUsername, uri.toString());
mMessageDatabaseReference.push().setValue(friendlyMessage);
Toast.makeText(MainActivity.this, "Photo Uploaded and URL is : " + uri.toString(), Toast.LENGTH_SHORT).show();
}
});
}
});

This code will work but it will create a two images in the Firebase Storage, because when you call the
photoRef.putFile(selectedImageUri); mChatPhotosStorageReference.putFile(selectedImageUri)......
You once uploaded the file in the chat_photos folder and 2nd one outside the chat_photos folder i.e. the root folder.
Instead You should do this...
photoRef.putFile(selectedImageUri).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();
}
// Continue with the task to get the download URL
return photoRef.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
FriendlyMessage friendlyMessage = new FriendlyMessage(null,
mUsername, downloadUri.toString());
mMessageDatabaseReference.push().setValue(friendlyMessage);
} else {
// Handle failures
// ...
}
}
});
شباب هذة الكود الصحيح والكامل سبب الخطأ هو 1- تم تحديث الاكواد لأن اكواد هذة الدرس قديمة 2- يجب ان تكون الاقواس منفصلة عن اقواس الدرس السابق لمصادقة تسجيل الدخول اتمنى ان يعمل معكم الكود

Hey guys, according with the documentation:
else if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) {
Uri selectImageUri = data.getData();
final StorageReference photoReference = mChatPhotoStorageReference.
child(selectImageUri.getLastPathSegment());
UploadTask uploadTask = photoReference.putFile(selectImageUri);
Task<Uri> uriTask = 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();
}
// Continue with the task to get the download URL
return photoReference.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
@Override
public void onComplete(@NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
FriendlyMessage friendlyMessage = new FriendlyMessage(null, mUsername, downloadUri.toString());
mMessageDatabaseReference.push().setValue(friendlyMessage);
}
}
});
i have found the solution my code was also not working because the main issue is that all of our logic was surrounded by the if(requestCode == RC_SIGN_IN) block in the start of the onActivityResult method
and if u want to ur ui to get updated instantly and if your image get uploaded to the firebase storage and the ui does not get update comment out the code in the onpause and you will be good to go
