You definitely should not edit <code>R</code> file manually. There seems to be something wrong with your IDE environment that this file does not get re-generated on changes.

blocks|key|1784291|text|您不应该手动更改R.java。该文件由android构建工具维护。您没有看到r.java刷新的原因是您的开发环境中的文件同步问题。我在mac中使用Intellij，从来没有遇到过这个问题，但即使我遇到了这个问题，IDE中也有一个同步选项，用于用文件系统刷新项目内容。我确信在每个集成开发环境中都有一个等效的命令(很可能是刷新)，并且再一次不要编辑R.java。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1784292|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You should never alter R.java manually. That file is maintained by android build tool. The reason you are not seeing r.java refreshed is an file synchronizing problem in your dev environment. I use Intellij in mac and have never faced this problem, but even if I do, then is a synchronize option in my IDE to refresh project content with file system. I am sure an equivalent command exists in every IDE ( most probably refresh) and once again do not edit R.java.

blocks|key|3856179|text|如果您正在使用eclipse，您是否尝试过右键单击/res文件夹并选择“刷新”(或按F5)。R.java只能自动生成，不能手动编辑。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3856180|此外，我不确定这是否是您所要求的，但是您不能在任何/res目录中放置更多的子目录。|3856181|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

If you are using eclipse, have you tried right clicking on the /res folder and selecting "refresh" (or pressing F5). R.java should only ever be automatically generated and not edited manually.

Also, I'm not certain if this is what you're asking, but you cannot place further sub-directories within any of the /res directories.

You should not manually modify R.java
In Eclipse under 

<blockquote>
 Project-> Build Automatically
</blockquote>

Tick it. So whenever you modify something. It will build automatically.
Still if you face problem then clean the the project.

<blockquote>
 Project-> Clean
</blockquote>

blocks|key|2247945|text|让我猜猜您使用的是eclipse。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2247946|最好是在Project->Build+Automatically中启用选项Build+Automatically。|2247947|当您遇到此问题时(R文件不是自动生成的)，请执行以下步骤。|2247948|1.右键单击项目，然后单击“关闭不相关的项目”|2247949|2.刷新您当前的工作项目，确保您看到所有新内容都在res文件夹中。|2247950|3.现在取消选中Build+Automatically，然后从项目菜单中单击Build+All。|2247951|4.现在清理项目。|2247952|希望你的问题现在已经解决了。|2247953|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|V|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|W|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|X|8|@]|9|@]|A|$]]|$1|N|3|O|5|6|7|Y|8|@]|9|@]|A|$]]|$1|P|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|Q|$]]

Let me Guess you are using eclipse.

It is all ways better to enable the option Build Automatically in Project->Build Automatically.

When you face this problem( R file not generated automatically) follow the following steps.

1.Right Click on the project and click "Close Unrelated Project"

2.Refresh you current working projects and make sure you see all your new contents are there in the res folder.

3.Now Uncheck Build Automatically and Click Build All from the project menu.

4.Now clean the project.

Hope your problem is solved now.

blocks|key|3856281|text|我在我的案例中遇到了这个问题，我在drawable文件夹中添加了一个大写字母的图像，所以我在控制台中得到了类似"res\drawable-hdpi\addBut.png:+Invalid+file+name:+too.In+a-z0-9_“的通知。删除此文件后，无法对R.java文件进行refreshed.All解析。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3856282|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had this problem too.In my case I had add an image in drawable folder with a capital letter an it so I had o notification in the console like "res\drawable-hdpi\addBut.png: Invalid file name: must contain only [a-z0-9_.]" and the R.java file could not be refreshed.All solved after removing this file.

I am working in android SDK(Eclipse) platform 2.2 and I have been running through some tutorials, and some of them say to just add files to existing folder, or add folders; with files inside them. At several points when I create a new folder and place a new file inside it, and code everything corectly R.java does not recognize the new folder, or even the new file(constants, buttons, strings, reference ids). several times now I have had to go in and manuallly alter R.java (adding classes, and constants) by hand.

So my question is multi-facited:
does R.java not expect me to create new folders, and files, and in turn live inside the given folders and files (making multi activity application near-impossible)?

If I have to alter R.java by hand is there any specific consideration to naming and numbering(memory address) that I should follow?

Is there any way for me to get R.java to recongnize that a folder/file/class/constant even exists without having to brute force enter it?
