Question

我在代码上遇到问题非常正常。我正在运行一个异步任务来从android中的web服务器获取数据，问题是当控件进入异步任务中的readLine时我得到一个异常，详情如下：

library(ggplot2)
dtf <- data.frame(year = rep(1961:2010,2),
                  consumption = cumsum(rnorm(100)),
                  item = rep(c("Tea~bags","Coffee~beans"),each=50),
                  unit = rep(c("T","m^3"),each=50))
ggplot(data=dtf)+
  geom_line(aes(x=year, y=consumption),size=1) +
  ylab(expression(paste("Consumption in T or ",m^3))) +
  scale_x_continuous(breaks = seq(1960,2010,10)) +
  theme_bw() + facet_wrap(item~unit, scales = "free_y",labeller = label_parsed)

堆栈跟踪：

BufferedReader reader = new BufferedReader(new
                        InputStreamReader(conn.getInputStream()));
                StringBuffer sb = new StringBuffer("");
                String line = "";

                while ((line = reader.readLine()) != null) {
                    sb.append(line);
                    break;
                }

我知道php中的数据没有损坏，我可以看到它正确地返回了对象。

这个问题突然出现，我知道这不是代码问题，因为没有进行代码更改，而且这个问题开始了。请建议。
