I only get a java.io.FileNotFoundException: No such file or directory exception. Earlier I tried saving it with an Success-Listener as it's shown here: https://stackoverflow.com/a/50743192/6274419. But that also hadn't worked because the function doesn't exist in the newer Firebase version.
In general I want to display a profile picture and the username which are saved to Firebase and retrieved on next application startup.
Thanks in Advance!

It takes some time to upload the image in firebase. So you can only retrieve the image when it is completely saved in database. Please call the loadUserData() method in OnSuccess and let me know if it works.
private void uploadToFirebase() {
//Select destination filename, folder
profileimageRef = FirebaseStorage.getInstance().getReference("profilepictures/" + System.currentTimeMillis() + ".jpg");
Log.wtf("ImageURL", profileimageRef.toString());
//Upload image
if(uriProfileImage != null)
{
//Show progressbar
progressBar.setVisibility(View.VISIBLE);
profileimageRef.putFile(uriProfileImage).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
//Hide progressbar
progressBar.setVisibility(View.GONE);
//Check if was successful
if(task.isSuccessful())
{
//Set profile image url
profileimageurl = task.getResult().toString();
loadUserData();
Log.wtf("ImageURL2", profileimageurl);
}else
{
Toast.makeText(ProfileActivity.this, task.getException().getLocalizedMessage() , Toast.LENGTH_SHORT).show();
}
}
});

Solved it now by using another structure/method for retrieving the url with a UploadTask:
private void uploadToFirebase() {
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReference();
//Select destination filename, folder
final StorageReference profileimageRef = storageRef.child("profilepictures/" + System.currentTimeMillis() + ".jpg");
UploadTask uploadTask = profileimageRef.putFile(uriProfileImage);
Log.wtf("ImageURL", profileimageRef.toString());
//Upload image
if(uriProfileImage != null)
{
//Show progressbar
progressBar.setVisibility(View.VISIBLE);
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();
}
return profileimageRef.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
progressBar.setVisibility(View.GONE);
if(task.isSuccessful()) {
profileimageurl = task.getResult().toString();
}
}
});
}
}
