in my application, I have pdf files. I want to save those pdf files into my database. I am using SQLite as my Backend. How can I format those pdf file into bytes.

推荐答案

您可以简单地读取pdf文件的所有字节并将其存储在sqlite DB的blob字段中，但是强烈建议您使用以下更好的解决方案:内部存储器和数据库中的文件仅存储文件的路径.您还必须检查是否有足够的内存存储空间供您使用.

You can simply read all the bytes of the pdf file and store them in the blob field of sqlite DB, but a better solution which is highly recommended is to store the files on the Internal Storage and in your DB just store the file's path. You have also to check if there is enough memory storage for you.
