序列化为json字符串或二进制

Question

I need to persist a object. Unfortunately sqlite in android does not support ORM. Therefore I need to choose a different way to persist my data.

Is it better to persist the data via java serialization (ObjectOutputStream) within a blob, or via Gson's json serialization as a json string? Afterwards I need to serialize the data again as a json string in order to transmit it to a restful wcf service.

I'm worried about the serialization speed because afaik working with strings isn't very efficient.

Answer 1

In my experience serialization works faster than gson, but I haven't done any test on it. If speed is of concern I'd recommend you to do that test yourself.

On another note, you can use ORM on java/Android, read here: Any good ORM tools for Android development?
