Why learn one way for Java and another way for everything else? Your Java apps can now use the same calls as JavaScript apps. QCJSON is as easy as that.
QCJSON specifically supports Android development. Need to communicate accross the network? Use the usual HTML clients or your own sockets. QCJSON supports them both.
We all know that all of our mobile apps should be multi-threaded to make them responsive. QCJSON protects your streaming JSON from other threads. It's easy. It's fast.
