android - logcat中的adjustAdaptiveCoef错误是什么意思？

Question

我正在开发一个 android 应用，有时会出现类似以下的错误:

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

有谁知道它们的意思，或者是否有任何顾虑？

Answer 1

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

通常，如果您的应用不是一次处理大量图像(即:一个 GridView 图像)，则您不应该特别注意这些错误。

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。
