eclipse 无法“构建工作区”在大型 Android 文件上...？
我有一个严重的 Eclipse 问题，我需要编译一个更大的类。我所说的“更大”是指，该类大约有 5000 行代码...
问题是，在保存该项目时，Eclipse 需要几秒钟（30-40）来“构建工作区”。准确地说，它显示“50%”，并持续显示 30-40 秒。然后，它会因以下错误而中断：
[console]:
[2010-07-09 15:28:39 - Dex Loader] 无法执行 dex: null
[2010-07-09 15:28:39 - myProject] 转换为 Dalvik 格式失败：无法执行 dex: null
[问题窗口]:
转换为 Dalvik 格式失败：无法执行 dex: null
此错误是可重现的，并且不断弹出，直到我注释掉数千个 LOC，以便该文件仍然具有这 5k LOC，但其中大约 2000 个是注释。然后它就起作用了...
我知道 5000 LOC 并不是真正好的编程风格，但我现在需要这样做...（我必须将这么多记录写入 sqlite 数据库，因为 sqlite 不具有多个 sql - 在一个 rawQuery 命令中的查询，我必须为我需要推入数据库的每一个数据记录执行一个 rawQuery() ... - 直到我编写一个文件读取器来从文件中读取此数据（需要验证等）），我坚持这个解决方案...）
我如何让 Eclipse 和 android sdk 接受这么大的文件？

i have a severe problem with eclipse, where i need to compile a somewhat larger class. by "larger" i mean, the class has about 5000 lines of code...
problem is that on saving this project, eclipse takes several seconds (30-40) to "build the workspace". to be exact, it says "50%" and keeps saying that for 30-40 seconds. then, it breaks with the following error:
[console]:
[2010-07-09 15:28:39 - Dex Loader] Unable to execute dex: null
[2010-07-09 15:28:39 - myProject] Conversion to Dalvik format failed: Unable to execute dex: null
[problems window]:
Conversion to Dalvik format failed: Unable to execute dex: null
this error is reproducible and keeps popping up until i comment out several thousands LOC, so that the file still has this 5k LOC, but ~2000 of them are comments. THEN it works...
i know that 5000 LOC are no really good programming style, but i need to do it this way for now ... (i have to write this much records to a sqlite database and since sqlite doesnt feature multiple sql-queries in one rawQuery-command i have to execute a single rawQuery() for each and every data record i need to push into the db.... - until i write a file reader to read this data from a file (that needs verification etc)), i'm stuck with this solution...)
how do i get eclipse and the android sdk to accept files this big?

我相信在 Dalvik 中类的字节码大小不得超过 64k。你必须把班级分成更小的班级。
I believe the size of a class's bytecode must not exceed 64k in Dalvik. You'll have to split the class into smaller ones.
