Android Firebase Получить URL-адрес изображения

/ 09 июня 2018

Я хочу получить DownloadUrl из изображения, которое я загрузил в Firebase, но когда я пытаюсь загрузить его позже, я получаю только не найденное исключение: 

public class ProfileActivity extends AppCompatActivity{

private static final int CHOOSE_IMAGE = 200;
//Initialize items
EditText inputUsername, inputBirthday;
FloatingActionButton mainaction;
FloatingActionButton homeaction;
FloatingActionButton profileaction;
StorageReference profileimageRef;
String profileimageurl;
Button actionSaveProfile;
FirebaseAuth mAuth;
ProgressBar progressBar;
ImageView profileimage;
Boolean isfabopen;
Uri uriProfileImage;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_profile);


    isfabopen = false;
    mainaction = findViewById(R.id.fab_expand);
    homeaction = findViewById(R.id.fab_home);
    profileaction = findViewById(R.id.fab_profile);
    inputUsername = findViewById(R.id.input_username);
    inputBirthday = findViewById(R.id.input_birthday);
    actionSaveProfile = findViewById(R.id.action_save_profile);
    profileimage = findViewById(R.id.profile_image);
    progressBar = findViewById(R.id.progressbar);
    mAuth = FirebaseAuth.getInstance();

    //Expand, collapse menu
    mainaction.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(!isfabopen)
            {
                ShowFab();
            }else
            {
                CloseFab();
            }
        }
    });

    profileimage.setOnClickListener(new View.OnClickListener() {
        @Override

            showImageChooser();
        }

    loadUserData();

        Glide.with(this)
                .load(user.getPhotoUrl().toString())
                .into(profileimage);
    }

    //If no username found
    if(user.getDisplayName() != null)
    {
        String username = user.getDisplayName();

        //Insert display name
        inputUsername.setText(user.getDisplayName());
    }

Я получаю только исключение java.io.FileNotFoundException: нет такого исключения файла или каталога.Ранее я пытался сохранить его с помощью Success-Listener, как показано здесь: https://stackoverflow.com/a/50743192/6274419. Но это также не сработало, потому что функция не существует в более новой версии Firebase.

В общем, яхотите отобразить изображение профиля и имя пользователя, которые сохраняются в Firebase и извлекаются при следующем запуске приложения.

Заранее спасибо!

Решил это сейчас, используя другую структуру / метод для получения URL с помощью 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();
                }
            }
        });
    }

}

Загрузка изображения в Firebase занимает некоторое время.Таким образом, вы можете получить изображение, только когда оно полностью сохранено в базе данных.Пожалуйста, вызовите метод loadUserData () в OnSuccess и дайте мне знать, если он работает. 

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();
                    }

                }
            });
