我想知道是否有人可以引导我完成这一行：

GC_EXTERNAL_ALLOC freed 574K,paused 51ms

这个号码4255K / 7495K告诉我们什么？

解决方法 有人最近向我指出了一个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.尝试 Eclipse Memory Analyzer Open Source Project.您可以单击 DDMS“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.

顺便说一句,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.
