如果对下面的代码进行分析，您将看到有4个函数被多次调用(pushNextEntityUpdatedRows、pushNextUpdatedRow、pushNextEntityCreatedRows、pushNextCreatedRow)，这不是一个BUG，这是我如何设计代码来工作的。您应该知道的是，我有一个扩展SQLiteOpenHelper的类(DataAccess)，我只实例化该类一次。每次调用函数pushNextEntityUpdatedRows和pushNextEntityCreatedRows时，都会在pushNextEntityCreatedRows类实例中执行rawQuery。我从不关闭连接，只关闭游标对象实例。我不知道是什么导致了这个StackOverflowError.我也不知道为什么它总是发生在145调用之后。我该怎么解决呢？谢谢你提前了。

堆栈跟踪告诉我如下：

看起来，在某个地方有一个循环或递归函数，它没有到达循环/函数的中断/结束。大多数情况下，当您使用if语句检查递归函数的结尾时，它实际上从未改变if语句的条件。

在某种程度上，您的计算机没有足够的“思考空间”，无法深入到兔子洞中(因为每次迭代都占用了整个空间的某一部分，可以简单地说出来)。显然，在145次迭代中，您已经达到了极限。

如果没有这些代码，我们在这里无法真正帮助您，那么添加一个示例代码如何？
