我想知道是否有人可以引导我完成这一行：

GC_EXTERNAL_ALLOC freed 574K, 44% free 4255K/7495K, external 1182K/1846K, paused 51ms

这个数字 4255K / 7495K 告诉我们什么？

1 个答案:

答案 0 :(得分：4)

最近有人向我指出了一个Eclipse插件（在简单地浏览它之后）似乎非常有效地发现了内存泄漏。试试Eclipse Memory Analyzer Open Source Project。您可以单击DDMS中“设备”选项卡下的“转储HPROF文件”，获取堆信息的信息/图表。它看起来很整洁。

顺便说一下，您正在质疑的数字似乎是应用程序heap大小的可用/容量。 GC_EXTERNAL_ALLOC在this post中有更多描述。
