Firebase 存储和图像查看

Question

I want to get image from Firebase Storage and than show at Image View. I trying this code but not working. Always I getting my "ERROR" toast message. App is opening but I dont see my JPEG.

** I found one way but it is not enough for me.

If I delete 'com.google.firebase:firebase-auth:19.3.2' from build gradle, this code working. I need FirebaseAuth because I have User login and logout page. Do you know another way for Firebase storage and image ?

Thank you for help.

enter image description here

private StorageReference mStorageReference;
ImageView imageView;


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

mStorageReference=FirebaseStorage.getInstance().getReference().child("vardiyaandroid.jpeg");
    final File localfile;
    try {
        localfile = File.createTempFile("vardiyaandroid","jpeg");
        mStorageReference.getFile(localfile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
                Toast.makeText(vardiya.this,"Resim Hazır",Toast.LENGTH_LONG).show();
                Bitmap bitmap = BitmapFactory.decodeFile(localfile.getAbsolutePath());
                (imageView=findViewById(R.id.imageView)).setImageBitmap(bitmap);

            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(vardiya.this,"ERROR",Toast.LENGTH_LONG).show();

            }
        });
        

    } catch (IOException e) {
        e.printStackTrace();
    }

Answer 1

I found my false.

1. You will change this code

   mStorageReference=FirebaseStorage.getInstance().getReference().child("vardiyaandroid.jpeg");

   with

mStorageReference=FirebaseStorage.getInstance().getReferenceFromUrl("gs://YOURAPPID.appspot.com/vardiyaandroid.jpeg"); StorageReference pathreferance =mStorageReference.child("vardiyaandroid.jpeg");

and the storege rules must be this:



rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, writ, auth: if true;
    }
  }
}
