Eclipse的LogCat充斥着带有android的WAIT

Eclipse的LogCat充斥着带有android的WAIT_FOR_CONCURRENT_GC(Eclipse's LogCat gets flooded with WAIT_FOR_CONCURRENT_GC with android)

我正在写一个小型安卓游戏，每当我第一次运行时，一切都运行良好，但它会随机挂起并开始在eclipse的LogCat中无休止地发送垃圾邮件

12-30 12：40：05.344：D / dalvikvm（22831）：WAIT_FOR_CONCURRENT_GC阻塞5ms 12-30 12：40：05.383：D / dalvikvm（22831）：GC_CONCURRENT释放511K，34％免费2374K / 3552K，暂停1ms + 2ms ，总共14ms

我知道它与垃圾收集有关，但每当我强制停止应用程序（关闭它的唯一方法）时，我会丢失大约5-10mb的可用内存，直到我重新启动设备。 有谁知道这意味着什么以及如何预防？

我正在使用的设备是运行android 4.2.1（Cyanogenmod 10.1）的verizon galaxy nexus和3.2（api level 13）的sdk / target版本。 谢谢！

I am writing a small android game, and whenever I first ran, everything worked fine, but it will randomly hang and start spamming this endlessly in eclipse's LogCat

12-30 12:40:05.344: D/dalvikvm(22831): WAIT_FOR_CONCURRENT_GC blocked 5ms 12-30 12:40:05.383: D/dalvikvm(22831): GC_CONCURRENT freed 511K, 34% free 2374K/3552K, paused 1ms+2ms, total 14ms

I know it has something to do with garbage collecting, but whenever I force stop the app(the only way to close it) I lose around 5-10mb of available ram until I restart the device. does anyone know what this means and how to prevent it?

the device I am using is a verizon galaxy nexus running android 4.2.1(Cyanogenmod 10.1) and sdk/target version at 3.2(api level 13). Thanks!

您将能够以自己的方式进入更详细的描述，但基本上它只是意味着您正在使垃圾收集器非常努力。

编程游戏不同于编写“普通”应用程序：您的游戏可能无数循环。 因此，即使是微小的内存泄漏也会迅速增长，成为一个真正的问题。

此外，GC也是你最大的朋友，在游戏中它几乎是你的敌人之一。 每次GC运行都会产生一些冻结，因为它“阻止了世界”。

我建议你继续搜索特定的游戏编程教程，以及如何在这些教程中对抗GC。

You'll be able to Google your way into a much more detailed description, but basically it just means you're making the garbage collector work very hard.

Programming a game is different from programming a 'normal' app: your game probably loops countless of times. As a result of this even a tiny memory leak can grow quickly to a real problem.

Furthermore, GC is normall your biggest friend, in gaming it is pretty much one of your enemies. Every GC run creates a little freeze since it 'stops the world'.

I'd suggest you continue your search in specific gaming programming tutorials and how to work against the GC in those.
