java - 调用 user.getPhotoUrl() Firebase 时出现安全异常

Question

我目前正在开发一个 Android 应用程序，我必须允许用户使用个人资料图片注册，我能够使用用户名、电子邮件和照片等字段注册用户。当我尝试使用刚刚创建的同一用户重新登录时出现问题，这给了我以下错误....

权限拒绝:从 ProcessRecord 打开提供程序 com.google.android.apps.docs.storagebackend.StorageBackendContentProvider .....................需要您使用 ACTION_OPEN_DOCUMENT 或相关 API 获得访问权限

下面是我创建用户的代码

mAuth.createUserWithEmailAndPassword(email, password)
            .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {

                        FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

                        UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                                .setDisplayName(uname).setPhotoUri(ImgUri).build();

                        user.updateProfile(profileUpdates);
                        Toast.makeText(getApplicationContext(), "Registration successful!", Toast.LENGTH_LONG).show();
                        progressBar.setVisibility(View.GONE);
                        Intent intent = new Intent(RegisterActivity.this, Login.class);
                        startActivity(intent);
                        finish();
                    }
                    else {
                        Toast.makeText(getApplicationContext(), "Registration failed! Please try again later", Toast.LENGTH_LONG).show();
                        progressBar.setVisibility(View.GONE);
                    }
                }
            });

这是我选择图像的代码

private void chooseImage() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {

        ImgUri = data.getData();
        System.out.println(ImgUri);

        try {
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), ImgUri);
            // Log.d(TAG, String.valueOf(bitmap));

            ImageView imageView = findViewById(R.id.userImg);
            imageView.setImageBitmap(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

下面是我尝试检索用户个人资料图片时的代码

  FirebaseUser user = mAuth.getCurrentUser();
    System.out.println(user.getPhotoUrl());
    img.setImageURI(user.getPhotoUrl());

我是否需要将 ImageUri 保存到 Firebase 存储以及 Firebase 实时数据库？或者是否需要任何权限？我需要吗

Answer 1

在拾取图像时为 Intent 添加 Action

private void chooseImage() {
   Intent intent=Intent(Intent.ACTION_OPEN_DOCUMENT);
   intent.setType("image/*");
   startActivityForResult(Intent.createChooser(intent, "Select Picture"), 
   PICK_IMAGE_REQUEST);
}

ACTION_OPEN_DOCUMENT is not intended to be a replacement for ACTION_GET_CONTENT. The one you should use depends on the needs of your app:

Use ACTION_GET_CONTENT if you want your app to simply read/import data. With this approach, the app imports a copy of the data, such as an image file.

Use ACTION_OPEN_DOCUMENT if you want your app to have long term, persistent access to documents owned by a document provider. An example would be a photo-editing app that lets users edit images stored in a document provider.
