解决android项目系统崩溃：Exceptions are not yet supported across processes.

目前在开发一个android项目，其中有一个功能是读取联系人。我是一次性的联系人全部读出来，当联系人数量较少时，几十条，没有问题，超过200条时，则遇到问题是：项目每开启二次，就会崩溃一次，然后就这样下去。这个问题已经存在了好久，就是找不到症结。主要抛出的异常信息为： [color=red]ERROR/JavaBinder(3438): *** Uncaught remote exception! (Exceptions are not yet supported across processes.)
ERROR/JavaBinder(3438): java.lang.RuntimeException: No memory in memObj[/color]
部分日志信息显示如下：

[color=red]看来是内存泄漏了，可就找不到问题出在哪里。怀疑是查询sqlite数据库时没有关闭Cursor，看了下代码Cursor是在finally{}代码块中关闭的，没问题。问题究竟出在哪里，后来通过仔细查看代码，原来我在查询联系人时用了两层游标，我只关闭了外层游标，没有关闭里层的，导致内存资源没有被释放。多次运行后，系统资源被耗尽。[/color]
