我不知道是否有人可以通过这条线走我：
I wonder if anyone could walk me through this line:
GC_EXTERNAL_ALLOC freed 574K, 44% free 4255K/7495K, external 1182K/1846K, paused 51ms
这是什么号 4255K / 7495K 告诉我们？
推荐答案
最近有人向我指出一个Eclipse插件，（后短暂地看了一眼吧）似乎是非常有效的察觉内存泄漏。请尝试 Eclipse的内存分析器开源项目。你可以点击HPROF转储文件下的设备选项卡中 DDMS 并获得您的堆信息资讯/图形图表。它看起来非常整洁。
Someone recently pointed me to an Eclipse plugin that (after briefly glancing over it) seems to be very effective at spotting memory leaks. Try the Eclipse Memory Analyzer Open Source Project. You can click "Dump HPROF file" under "Devices" tab in DDMS and get info/graphical charts of your heap information. It looks really neat.
顺便说一句，你似乎都在质疑数字是应用程序的可用/容量堆大小。 GC_EXTERNAL_ALLOC描述更这个帖子。
BTW, it seems that the numbers you are questioning are the available/capacity of the applications heap size. GC_EXTERNAL_ALLOC is described more in this post.
