logcat中的adjustAdaptiveCoef错误是什么意思？

Question

我正在开发一个Android应用程序,有时会出现类似于以下内容的错误:

11-21 16:03:15.219:E/dalvikvm(17170):adjustAdaptiveCoef max = 4194304,min = 1048576,ut = 568 11-21 16:03:16.212:E/dalvikvm(17170):adjustAdaptiveCoef max = 4194304,min = 1048576,ut = 568 11-21 16:03:17.649:E/dalvikvm(17170):adjustAdaptiveCoef max = 4194304,min = 1048576,ut = 568

有谁知道他们的意思,或者他们是否有任何顾虑？

Answer 1

out of memory该错误似乎与Dalvik VM 的状况有关。发生此错误的最常见原因是当您（或操作系统）处理位图解码时。

一般来说，如果您的应用程序没有一次处理大量图像（即：图像GridView），您不应该太注意这些错误。

资料来源：我找不到任何官方文档。

编辑：这是导致 OutOfMemory 错误的典型堆栈跟踪。
