                        });


            }
        }

    });
}



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

    if (requestCode==Gallery_Pick && resultCode==RESULT_OK && data!=null){
        ImageUrl = data.getData();
        selectBookImage.setImageURI(ImageUrl);

    }
}

}

这是我在运行应用程序并将书添加到数据库时获取的错误，请注意，图像已成功上传，然后导致应用程序崩溃:

This is the Error Im getting when im running the app and adding book to database, Please note that Image is uploading successfully and then comes the app crash:

2018-11-11 02:03:13.068 29281-29281/com.example.t3hjeff.bookshelf E/AndroidRuntime: FATAL EXCEPTION: main

推荐答案

注意以下行:

bookTitle = (EditText) findViewById(R.id.addbookTitle);//bookTitle is an EditText object
...
booksMap.put("title",bookTitle);//it can not be serialized/deserialized

Firebase数据库只能存储JSON类型，因此您不能将EditText传递给它.

The Firebase Database can only store JSON types, so you cannot pass a EditText to it.

 Title = bookTitle.getText().toString();
 ...
 booksMap.put("title",Title );//modify like this.
