A while ago we hosted an article about using Gson for JSON parsing with Android<\/a>. The tutorial was a simple showcase of how to leverage Gson with Android<\/a>.<\/p>\n

Recently, Bill Mote from the AYDABTU Development<\/a> site contacted me and informed me that he had used our sample code in one of his Android applications, namely Broadcast SMS<\/a>. More specifically, he refined and improved the initial version in order to create a more robust parser.<\/p>\n

Let’s here what he has to say about his experience.<\/p>\n

I was in the midst of writing my first Android application and I wanted to make my app “phone home” to accomplish a few things:<\/p>\n

1. I wanted it to display a Message Of The Day (MOTD) to inform my customers of relevant information or to simply say thank you for their support occasionally,
\n2. I wanted it to present a list of features available in newer releases than is currently installed by any given user and provide them a vehicle for upgrading and
\n3. I wanted to set a low-water mark to disable older versions of the application.<\/p>\n

A JSON web service seemed like the natural solution for this, but as I mentioned above, “I was writing my FIRST Android app.” ;)<\/p>\n

I stumbled upon your Android JSON parsing with GSON<\/a> article. What a wonderful and timely find! I know the article was simply intended to get the user started. Almost all articles are written this way. I want to give something back so I’ve taken your original article and expounded on it by hardening the HTTP request and the actual parsing of the JSON. I’ve also made the entire thing run in an AsyncTask (background thread) to get it off the UI thread as any kind of network hiccup or a large JSON string could cause the UI to become unresponsive and generate an error.

<\/div> <\/div><\/p>\n

The full-on Try\/Catch code can be found here: JSON Parsing Full Try-Catch<\/a>.<\/p>\n

Improvements:<\/p>\n

* Runs as an AsyncTask to get it off the UI thread
\n* Handles socket\/network timeouts
\n* Handles 404 errors
\n* Handles JSON syntax errors<\/p>\n

Of note:<\/p>\n
