Light And Fast Android Json Parser?

When I started project I went with GSON as most completed and with a good backing. I feel now that it is not performing very well. So, let's say when I load an array of 200 items

Solution 1:

I've gotten fairly significant performance improvements by switching from GSON to Jackson in past projects.

Solution 2:

Have you tried the org.json parser?

Solution 3:

Comparing json parser libraries.

Big File Results

Small Files Results

Choosing which library to use on the merit of parsing speed comes down to your environment then.

• If you have an environment that deals often or primarily with big JSON files, then Jackson is your library of interest. GSON struggles the most with big files.
• If your environment primarily deals with lots of small JSON requests, such as in a micro services or distributed architecture setup, then GSON is your library of interest. Jackson struggles the most with small files.

• If you end up having to often deal with both types of files, JSON.simple came in a very close 2nd place in both tests, making it a good workhorse for a variable environment. Neither Jackson nor GSON perform as well across multiple files sizes
