<h3>This answer is <a href="https://stackoverflow.com/questions/5889833/android-library-assets-folder-doesnt-get-copied">out of date</a>, the <a href="http://tools.android.com/tech-docs/new-build-system" rel="nofollow noreferrer">gradle build system</a> and AAR files support assets.</h3>

<hr>

From the <a href="http://developer.android.com/guide/developing/projects/index.html" rel="nofollow noreferrer">Android Docs</a>:

<blockquote>
 Library projects cannot include raw assets
 
 The tools do not support the use of raw asset files (saved in the assets/ directory) in a library project. Any asset resources used by an application must be stored in the assets/ directory of the application project itself. However, resource files saved in the res/ directory are supported.
</blockquote>

If you want to include files from a Library project, you'll need to put it in the resources instead of the assets. If you're trying to load HTML files from your library project into a WebView, this means that you'll have to go a more roundabout method than the usual asset URL. Instead you'll have to read the resource data and use something like <a href="http://developer.android.com/reference/android/webkit/WebView.html#loadData%28java.lang.String,%20java.lang.String,%20java.lang.String%29" rel="nofollow noreferrer">loadData</a>.

Okay. Ive been stressing out and losing sleep about this for a while. Im the type of person that loves API creation, and HATES complicated integration.

There arent many solutions around on the internet, so im quite proud of what Ive discovered with a bit of Eclipse Hackery.

It turns out that when you put a file in the Android Lib's /assets folder. The target apk will capture this and place it on the root of the APK archive. Thus, making general access fail.
This can be resolved by simply creating a Raw Java Library, and placing all assets in there, ie (JAVALIB)/assets/fileX.txt.

You can in turn then include this as a Java Build Path Folder Source in 
Project > Properties > Java Build Path > Source > Link Source.

<ol>
<li>Link Source</li>
<li>Click on Variables. and Add New Variable, ie VAR_NAME_X. location : ../../(relative_path_to_assets_project)</li>
<li>Click Ok</li>
</ol>

Now, when you build and run your app, the assets folder in the APK will contain your (GLOBAL Library) files as you intended.

No need to reconfigure android internals or nothing. Its all capable within a few clicks of Eclipse.

blocks|key|264932|text|我确认Daniel+Grant的方法至少适用于以下情况:目标项目没有资产文件夹(或者该文件夹是空的，因此您可以安全地将其删除)。我没有设置任何变量。只需按如下方式设置一个资产(仅是一个示例)链接文件夹位置:+/home/matthew/workspace_moonblink/assetsForAdvocacy/assets文件夹名称:+LinkSource|type|unstyled|depth|inlineStyleRanges|entityRanges|data|264933|"+assets“是一个Java项目(用New-+project+-+Java+project创建)，其中有一个空的src文件夹，还有一个名为"assetsForAdvocacy”的新文件夹，它现在为目标项目提供了整个assets文件夹。|264934|在Eclipse中，这是一种相当简单的方法，可以在许多不同的项目中提供资产重用，如果它们还没有资产的话。从长远来看，我可能想增强它成为一个内容提供商，但这是更多的发展。|264935|我的项目使用以下代码访问资产:+String+advocacyFolderInAssets+=+"no_smoking/"；//+assets下的文件夹/+String+fn+=advocacyFolderInAssets%2BimageFilename；位图pristineBitmapForAdvocacy+=+getBitmapFromAsset(context，fn)；|264936|我在Ubuntu上使用Motodev+Studio+3.1.0。它不允许我将仅包含资产的新项目中的新资产文件夹‘合并’到目标项目中的现有资产文件夹中。|264937|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

I confirm that Daniel Grant's approach works for at least the following situation: target project does NOT have an asset folder (or the folder is empty, so you can safely delete it). 
I did not setup any variable.
Simply setup a LinkSource as follows (just an example)
 Linked folder location: /home/matthew/workspace_moonblink/assetsForAdvocacy/assets
 Folder name : assets

The "assetsForAdvocacy" is a Java project, (created with New- Project - Java Project) with empty src folder, and a new folder named "assets", which now provides the entire assets folder for the target project. 

This is a fairly straightforward way within Eclipse to provide assets re-use across many different projects IF they do not already have assets, good enough to get going with. I would probably want to enhance it to become a content provider in the long run, but that is a lot more development. 

My project accesses the assets with the following code:
 String advocacyFolderInAssets = "no_smoking/"; //a folder underneath assets/
 String fn =advocacyFolderInAssets+imageFilename;
 Bitmap pristineBitmapForAdvocacy = getBitmapFromAsset(context, fn);

I use Motodev Studio 3.1.0 on Ubuntu. It would not let me 'merge' a new assets folder in the new assets-only project onto an existing assets folder in the target project.

blocks|key|264949|text|您可以通过在项目的资产文件夹中创建指向库项目中的目录的符号链接来实现此目的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|264950|如下图所示即可访问：|264951|webview.loadUrl("file:///android_asset/folder_in_a_libary_project/info.html",+null);|code-block|syntax|javascript|264952|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can achieve this by creating a symbolic link in the project's asset folder that points to the directory in the library project.

Then you can access as below:

<pre><code>webview.loadUrl("file:///android_asset/folder_in_a_libary_project/info.html", null);
</code></pre>

blocks|key|2959046|text|如果您希望使用从一个库创建多个派生产品的设置，则可以考虑在SCM系统中使用svn:externals或类似的解决方案。这也会使静态资源，如在线帮助，可以从android源代码中分离出来。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2959047|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|$]]

If you want to use a setup where multiple derivate products are created from one library you might consider using svn:externals or similar solution in your SCM system. This will also do the trick that static assets like online help may be versioned seperately from the android source code.

blocks|key|3172936|text|现在，使用Gradle构建系统可以做到这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3172937|使用Android+Studio+0.5.0和Android+Gradle插件的v0.9进行测试，我发现如下文件|3172938|MyLibProject/src/main/assets/test.html|code-block|syntax|javascript|3172939|在最终应用程序中正确打包，并可在运行时通过预期的URL进行访问：|3172940|file:///android_asset/test.html|3172941|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

This is now possible using the Gradle build system.

Testing with Android Studio 0.5.0 and v0.9 of the Android Gradle plugin, I've found that files such as 

<pre class="lang-none prettyprint-override"><code>MyLibProject/src/main/assets/test.html
</code></pre>

are correctly packaged in the final application and can be accessed at runtime via the expected URL:

<pre class="lang-none prettyprint-override"><code>file:///android_asset/test.html
</code></pre>

In a class belonging to a Library project I call:

<pre><code>webview.loadUrl("file:///android_asset/info.html", null);
</code></pre>

Unfortunately, this only works if I duplicate the file info.html into the Application's project asset folder as well.

Is there a way to tell an Android library code: "look for this file in the library's assets folder, not in the application's assets folder" ?
