                            .addOnFailureListener(new OnFailureListener() {
                                @Override
                                public void onFailure(@NonNull Exception e) {
                                    Toast.makeText(getApplicationContext(),"Profile photo upload fail",Toast.LENGTH_SHORT).show();
                                }
                            });
                }
            }
        });

我编写了这段代码，用于插入用户注册期间拍摄的图像。但是，它给我一个错误，提示“个人资料照片上传失败。”我使用 Java for Android Studio，使用的数据库是 Firebase 数据库。

期望代码能够在 android studio 中使用 java 处理将图像插入到 firebase 中

尝试以下方法

if (filePath != null) {
    profilePhotoRef.putFile(filePath)
        .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                profilePhotoRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        String profilePhotoUrl = uri.toString();
                        helperClass.setProfilePhotoUrl(profilePhotoUrl);

                        if (collegeIdFilePath != null) {
                            // ...
                        } else {
                            Toast.makeText(getApplicationContext(), "College ID card Not selected", Toast.LENGTH_SHORT).show();
                        }
                        
                        // here display success message and navigate to login screen
                        Toast.makeText(getApplicationContext(), "Profile photo uploaded successfully", Toast.LENGTH_SHORT).show();
                        Intent i = new Intent(getApplicationContext(), Login.class);
                        startActivity(i);
                    }
                });
            }
        })
        .addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Toast.makeText(getApplicationContext(), "Profile photo upload failed", Toast.LENGTH_SHORT).show();
            }
        });
}

如果出现任何问题请告诉我？
