In order to load an small mp3 to the res/raw i created the folder raw in res... and added the file in the raw folder with New > File... so far so good...
为了将一个小的 mp3 加载到 res/raw，我在 res... 中创建了 raw 文件夹，并使用 New > File... 添加了 raw 文件夹中的文件...
BUT:
但：
MediaPlayer mp = MediaPlayer.create(context, R.raw.sound_file_1);
mp.start();
R.raw or any other way to get raw wont work.... and i can't get to the sound_file
if i look in class R.java it don't contains raw...
I really don't know what else i can do...
Maybe someone can help me please...
Thanks in advance
R.raw 或任何其他获取原始数据的方法都不起作用......
如果我查看 R.java 类中不包含原始数据的类，我将无法访问 sound_file ......
我真的不知道还有什么我可以做......
也许有人可以帮助我......
提前致谢

Thing you should be careful about :
你应该注意的事情：
1) that your file name doesn't contain any illigal caracters. if it does then it will fail to create the R file correctly and so you can't use R (the error message appears in the the regular eclipse console)
1) 您的文件名不包含任何非法字符。如果是，那么它将无法正确创建 R 文件，因此您无法使用 R（错误消息出现在常规 Eclipse 控制台中）
2) check that you have "loaded" your file to the project do ctrl (or cmd on mac)+shif+o on the root of your project in elcipse browser (reloads all resources) then F5 to refresh the files structures and the a clean project to force a nice clean build
2）检查您是否已将文件“加载”到项目中，在elcipse浏览器中的项目根目录上执行ctrl（或mac上的cmd）+ shif+o（重新加载所有资源），然后按F5刷新文件结构和a干净的项目来强制一个漂亮的干净构建
3) you could check if you have the RIght R files imported to your project, there is a default R file something like android.R instead of projectPackages.R
3）你可以检查你是否有正确的 R 文件导入到你的项目中，有一个默认的 R 文件，比如 android.R 而不是 projectPackages.R

You need to rebuild/recreate R.java - that file is generated on demand.
您需要重建/重新创建 R.java - 该文件是按需生成的。
In Eclipse this may need a "clean & build" action. You may also refresh the project in the project view, it will repopulate all the assets and when you build, it will repopulate R.raw for you
在 Eclipse 中，这可能需要“清理和构建”操作。您也可以在项目视图中刷新项目，它会重新填充所有资产，当您构建时，它会为您重新填充 R.raw
In IntelliJ IDEA, you have a context menu option "Force generate R.java" when you stand on such a resource file.
在 IntelliJ IDEA 中，当您站在这样的资源文件上时，您有一个上下文菜单选项“强制生成 R.java”。
NOTEThe R file won't be re-generated if you have a compilation error in one of your Java/XML files
注意如果您的 Java/XML 文件之一出现编译错误，则不会重新生成 R 文件

If the file has an all-caps filename, rename the file to all lower case. (An error message might appear: "Invalid file name: must contain only [a-z0-9_.]") I wonder if it is related to the case preserving but case insensitive file system on a mac? (I'm developing on a Mac.)
如果文件的文件名全部大写，请将文件重命名为全部小写。（可能会出现一条错误消息：“无效的文件名：必须只包含 [a-z0-9_.]”）我想知道它是否与 mac 上的大小写保留但不区分大小写的文件系统有关？（我正在 Mac 上开发。）

Be Careful, the same thing happened to me. Check your imports, I had a mistake and wrote
小心，同样的事情发生在我身上。检查您的导入，我有一个错误并写道
import android.R;
导入android.R;
Instead, I changed it for
相反，我改变了它
projectroot.mypackage.R;
projectroot.mypackage.R;

I had the same problem and I solved it.
The fact was that the file names were in Capital Ex, Song1.mp3... I only renamed it song1.mp3and it works..
我有同样的问题，我解决了它。事实是文件名在Capital Ex, Song1.mp3... 我只重命名了它song1.mp3并且它有效..

I renamed the music-file to only lower case letters and nothing else. Than it works (after long time researching).
我将音乐文件重命名为仅小写字母，仅此而已。比它有效（经过长时间的研究）。

Windows Explorer checks the audio file, not Eclipse.
Windows 资源管理器检查音频文件，而不是 Eclipse。
