小白开发，请教handler的顺序问题？

前提：收送指令皆是透过socket，手机为client端，另一设备为service端，service端会根据收到的指令，回复不同的讯息。只需负责手机端的行为。
问题：当user按下手中画面中的listview的选项时，系统先送出A指令，收到service回复的ack后再送B指令。
送出B指令之后等待 (35 + n*1) 秒 ( n为一个常数)，等待时间到达后，送出C指令。
送出C指令后等待10秒，再收service回复的信息，这时可能会是收到：RsrR@B=1=050505=1000000000=2105=ZN，则表示service端还没把需要的信息搜集好。
手机会再送一次C指令后再等10秒，再收service回复的信息，如果还是收到一样的讯息，则又再重复上述的行为一次(C指令总共只会送三次)。
如果在这重复三次的行为中有收到这种格式：RsrR@B=1=050505=1000000000=2105=02=030303=02020A，非ZN结尾的，则表示service端已把需要的信息搜集好，则停止送C指令的行为，直接跳转至另一个页面。
若三次都没有收到RsrR@B=1=050505=1000000000=2105=02=030303=02020A，这种格式的话，service端还是会送出另一种讯息。
想请问上述这些时间延迟的行为，要怎么写，我目前是写成这样，但执行出来的结果与想达成的目的不符合，求解。
