What is the best way to parse data to JSON and send it to web

Question

I have an offline app with lot of data. I need to convert the sqlite data to JSON and send it to web server.

I would like to know what is the best way to do that?

I would suggest using GSON library. Its by google and it is robust. Have a look at this link. https://github.com/google/gson — Ragesh Ramesh, Mar 15 '16 at 06:33
@KNeerajLal, app will be used on places without the internet and later, when it comes to the area with internet it will upload data to web. — RubyDigger19, Mar 15 '16 at 06:40
@RubyDigger19 I will give you a general idea to do so. See my answer. — K Neeraj Lal, Mar 15 '16 at 07:09

Use jackson or gson. Construct POJO object and use these libs to convert to json https://github.com/FasterXML/jackson

Should be straight to work on.

This is a borderline [link-only answer](http://meta.stackexchange.com/q/8231/213671). You should expand your answer to include as much information here, and use the link only for reference. – Tobi Nary Mar 15 '16 at 14:48

You need a BroadCastReciever that triggers when you get internet connectivity. Check this SO thread for more info.

Make a Service class that makes a webservice call to your website. I recommend using retrofit or volley library to make the webservice call. Here is the official guide to using retrofit.

Then use jackson/gson to convert your objects to json. See @autobot_101's answer on how to do that.

Pass this json data as a parameter to your webservice call. See this SO thread for more info.

Link only answers are not good but I think this should give you an idea of how to approach the problem.

Use Jackson API. You have to define a pojo, some annotations, and within no time you will have it running. Google Jackson API tutorials. Also there are some xml/json to pojo free online converters.

Lemme know if Google doesn't help you and I can write something quick for you.
