SOLUTION FOR: DEPRECATED >> Uri downloadUrl = taskSnapshot.getDownloadUrl

MainActivity.java

// Udacity - Does not working
@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RC_SIGN_IN) {
            if (resultCode == RESULT_OK) {
                Toast.makeText(getContext(), "Signed in!", Toast.LENGTH_SHORT).show();
            } else if (resultCode == RESULT_CANCELED) {
                Toast.makeText(getContext(), "Sign in canceled", Toast.LENGTH_SHORT).show();
                getActivity().finish();
            } 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());
                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
                                Uri downloadUrl = taskSnapshot.getDownloadUrl();

                                // Set the download URL to the message box, so that the user can send it to the database
                                ChatMessageClass friendlyMessage = new ChatMessageClass(null, mUsername, downloadUrl.toString());
                                mMessagesDatabaseReference.push().setValue(friendlyMessage);
                            }
                        });
            }
        }
    }

Thank you, this is really helpful

Muy útil, muchas gracias.

thanks a looooooot

I know what kind of feeling you might have had to get this sorted 😅.
I'm glad it helped.
Cheers.

Man... you don't know how much i am loving you right now. You just made my day.
Thank you so much.

There is one minor bug,

1. when you clicked on the photo picker button but press back button, a Toast appear with sign in cancelled.
2. When you logged out of the app, and then press back button , it keep moving in loops.
   --------SOLUTION---------
   Change the First : else if statements to this: by inserting requestCode ==RC_SIGN_IN to field and finish in the last.
   else if (requestCode == RC_SIGN_IN && resultCode == RESULT_CANCELED) { Toast.makeText(this, "Sign in canceled!", Toast.LENGTH_SHORT).show(); finish();

thank you

Man... you don't know how much i am loving you right now. You just made my day.
Thank you so much.

i think you should get married with him. by the way this man also solve my prob.

It finally solves the problem, but I still face an issue. The image is not shown right away but is shown when the app is loaded again. What is causing this, how can that be fixed?

thanks
