I am very proud to to you because it can create this application,
not hard to make this application for the java expert, but the problem is the complexity in generating the key which plays a fundamental role in this application and you have succeeded in doing so,
good work friend!
after I downloaded this application,
I tried to send a message to my friends who also have installed your application,
and the results are successful ..
user interface that is easy to understand is the superiority of your application:)
