service 没有unbind时was originally bound here错误

 在程序中，如果在activity中绑定了服务，而没有在destory中，写unbind，会出现这种异常，
Activity com.neusoft.dsn.infoplayer.InfoPlayerActivity has leaked ServiceConnection com.neusoft.dsn.infoplayer.InfoPlayerActivity$2@405189f8 that was originally bound here
解决办法，在destory中，加上context.unbindService(u'r ServiceConnection)
