为什么FDT在打包适用于iOS的Adobe AIR应用程序（.IPA）时显示Java堆错误 [英] Why Does FDT Show A Java Heap Error While Packaging an Adobe AIR app for iOS (.IPA)

问题描述

我正在使用Adobe AIR创建一些Flash游戏。我尝试将其编译为.ipa文件（以在iPad设备上运行）。

I'm creating some flash game using Adobe AIR. I try to compile it into .ipa file (to run on iPad device).

该项目规模不大，但规模也不小（它使用6个swc库和很多未预编译的代码）。我尝试使用两种方法将游戏与Flash FDT 5.5打包：

The project is not big, but not small also (it uses 6 swc libraries and lot's of not precompiled code). I try to package my game with Flash FDT 5.5 using both methods:

• fast -可以，但是性能很糟糕；


• 标准-我的编译完成并出现以下错误：

• fast - works ok, but the performance is terrible;
• standard - my compilation finishes with following error:

我知道这是Eclipse开发中的常见问题。我试图以标准方式解决->增加Java堆大小。如您所见，我设置了3072M，应该足够了。

I know that this is common issue with Eclipse devlopment. I tried to solve that in standard way -> increase java heap size. As you can see I've set 3072M which should be sufficient.

当我尝试编译较小的项目时，它可以正常工作。我不知道现在该怎么做:(。有什么想法吗？

When I try to compile smaller projects it works fine. I've got no idea what to do now :(. Any ideas?

推荐答案

经过深入调查后，我找到了解决方案

After deep investigation I've found a solution. It was NOT due to any enviromnent configuration, but, as @Alan said, Adobe's packager was running into problems. As I suppose, it was meeting problems while 'optimalization' phase.

Here's a forum topic that was really usefull: http://forums.adobe.com/message/4445973#4445973

我的项目使用的是NAPE物理引擎，我在那找到： http://deltaluca.me.uk/forum/index.php/m/2148/0ce4c49cc2c79979154c56737d2978a4/ 人们遇到了问题在我的情况下，编译时间是无穷大；），以Java的内存不足异常结束。解决方案是使用最新的NAPE构建，作者对此进行了一些优化。

My project was using NAPE physic engine. As I found there: http://deltaluca.me.uk/forum/index.php/m/2148/0ce4c49cc2c79979154c56737d2978a4/ people meet problems with compilation time. In my case the compilation time was infinity ;), what ended with java's out of memory exception. The solution was to use newest NAPE build, which was a little bit optimalized by the author. This 'small optimalization' made my project working.

总结：如果您有类似的问题，只需检查您的代码即可。尝试找到一些巨大的功能/方法，而Adobe的打包程序很难优化这些功能/方法。

To sum up: if you have similiar problem, just check your code. Try to find some huge functions/methods, which Adobe's packager finds hard to optimalize.
