Json parsing is a jar package, own research,
After the json parsing is complete, invoke Message. Obtain (); To create the Message object, the MSG. Obj assignment, value the parsed data for you, then call your handler invocation sendMessage (MSG); The data to send,

Create a handler object in which the rewrite handlerMessage (Message MSG) method
MSG. Obj is passed the data, you need casts,
Then calls the textView. SetText (STR) to update the UI
BltStatusHandler=new Handler () {
@ Override
Public void handleMessage (Message MSG) {
Super. HandleMessage (MSG);
String STR=(String) MSG. Obj;
TextView. SetText (STR);
}
};

//or String code=jsonObj. Get String (" code ")
