我认为我的问题可能与this stack post（Android远程方法数据限制）有关-仅返回的数据大小为661KB，并且文章说binder可以支持1MB。
情况如下：我有一个异步任务，它接受一个参数并调用一个 Web 服务，该服务返回一个由管道分隔的字符串和整数值组成的数组列表。然后我将这些值插入到 JAVA 数组列表中。在较小的数据集中，这很好用。在较大的数据集（即，这个 661KB 的数据集）中，我收到以下错误。

一旦意图开始，它就不会到达新的活动。我在 onCreate 中有一个 LOG.i，它永远不会被击中。过程调用没有超时。当我尝试返回较少数据的相同代码时，我没有收到错误消息。即，当我在将数据返回到异步任务的语句上放置一个 SELECT TOP 100 时，它完全没问题。
我想我的问题是——如果返回的数据小于 1MB，为什么会出错？如果是因为 1MB 的限制，我还能做些什么来绕过这个限制或以某种方式压缩返回的数据？
预期的设计是这个初始调用带回名称和与这些名称相关的约会（管道分隔）。我显示了一个仅包含微调器中名称的不同列表（取自数组列表）。当用户单击微调器中的名称时，它将启动一个新活动，该活动将显示与该名称关联的所有约会（同样，所有数据都来自初始数组列表）。所有数据都在第一个异步任务中收集并进行操作。这样做是为了减少网络调用的数量。这个任务在 2 个 Web 服务调用中是可行的，所以如果这是一个很好的答案 - 我只是希望有一种不同/更好的方法来做到这一点，这样我就可以限制 Web 服务调用并减少用户等待时间。
