SMSSender.java是一个用于发送短信的独立线程工具类。通过调用getSMSSender获取实例，设置地址和内容后启动线程即可发送。在发送过程中，如果成功会设置doSuccessfully为true，出现错误则设置errorOccured为true。

用法：
String add=address.getString();
String con=content.getString();
SMSSender smsSender = SMSSender.getSMSSender();
smsSender.setMessageText(add,con);
Thread t = new Thread(smsSender);
t.start();
