                        }
                    });
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override

                    Toast.makeText(activity, "failed", Toast.LENGTH_SHORT).show();
                }
            });
        }

        reference.push().setValue(hashMap);
        uri.clear();
        progressDialog.dismiss();
        startActivity(new Intent(activity, MainActivity.class));
        activity.finish();

    } else {
        progressDialog.dismiss();
        Toast.makeText(activity, "select payment received or not?", Toast.LENGTH_SHORT).show();
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(activity, "select Project Status", Toast.LENGTH_SHORT).show();
            }
        }, 1000);
    }
}

in the upper code addOnSuccessListener is not working

ImageName.putFile(IndividualImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        ImageName.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
            @Override
            public void onSuccess(Uri uri) {
                String URL = String.valueOf(uri);
                hashMap.put("image_url" + upload_count, URL);
            }
        });
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        Toast.makeText(activity, "failed", Toast.LENGTH_SHORT).show();
    }
});

please anyone knows the solution, please tell me. THANKS IN ADVANCE...

# 答案1
**得分**: 0
我解决了这个错误。我忘记将存储规则更新为公开。
****
上面的代码是没有错误的代码...所以，你可以使用这段代码来在Firebase存储上上传多张图片。***但是，不要忘记检查Firebase规则***，我在下面添加了规则。
****
**Firebase存储规则**
```firebase存储规则
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}```

**I solved the error. I forgot to update storage rules to public.**
****
upper code is error free code... so, you can use this code for upload multiple images on firebase storage. ***but, dont forget to check the firebase rules***, I am adding rules below.
****
**firebase storage rules**

rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}
