cur1.getCount返回所有3000条短信,但当我通过循环解析它时,它只运行400到500条短信

许多其他进程都在设备上运行,由于读取3000条消息的过程很长,需要大量的连续CPU时间,这就是进程被终止的原因。当我试着把它通读一遍时,效果很好

final int size = cur1.getCount();
final int sleeptimer = size;
final SMS [] sms = new SMS[size];

它会因为异常而中断吗?那么,在for循环的前400-500次迭代之后会发生什么呢?我看不出有任何明显的原因导致循环过早结束。logcat里有什么东西吗?
