i think the best option is to use <code>ant</code>, you'll need to add an ant target for each build and change the resource folder.
if you use the generated build.xml, the res folder is defined like this
<code>&lt;property name="resource.absolute.dir" location="res" /&gt;</code> so you'll want to override that

Why don't you use a single application, that does three different things based on SharedPreferences values set by the user, or from context at install time. If you really want to separate, you can have three different activities, and you decide which one to launch from a silent main Activity that redirects to either of the different ones.

An alternative is to have a unique activity that inflates itself dynamically from 3 different layouts at <code>onCreate</code> time.

<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 if (...custom check for layout... equals(layout1)) {
 setContentView(R.layout.main_layout1);
 } else if (... equals(layout2)) {
 setContentView(R.layout.main_layout2);
 } else if (... equals(layout3)) {
 setContentView(R.layout.main_layout3);
 } else {
 throw new IllegalStateException("Unknown layout!");
 }
 ... your onCreate stuff....
}
</code></pre>

It will make code maintenance easier (only one code source to modify, only one version-list and changeset to maintain)

Can't you put all of your common code into a library project and then just reference that project from each of the 3 unique projects that each contain the relevant resources.

Update: This answer is now obsolete when using the Gradle build system.

I would suggest using <a href="http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Product-flavors" rel="nofollow noreferrer"><code>Gradle</code> flavors</a>.

It seems to explain all the basics really well. I just finished converting to <code>Gradle</code> today, and it works great. Custom app icons, names, and strings, etc.

As the website explains, part of the purpose behind this design was to make it more dynamic and more easily allow multiple APKs to be created with essentially the same code, which sounds similar what you're doing.

I had developed 3 applications in android where the major functionalities are the same but the UI looks different. Images and the background color of the screens are different. 

NOw, i want to create a single code base from which i can generate multiple .apk files for the 3 apps. 

I tried creating 3 different packages for src folder for the 3 apps. But i dont know how to set the res folder for these apps. 

Need pointers on creating a single code base from which we can generate multiple .apk files which includes only the respective src and res folders.

Android - Multiple .apk file from single code base

我用android开发了三个应用程序，它们的主要功能是相同的，但UI看起来不同。图像和屏幕的背景颜色是不同的。NOw，我想创建一个单一的代码库，从中我可以为3个应用程序生成多个.apk文件。我尝试为这3个应用程序创建3个不同的src文件夹包。但我不知道如何为这些应用程序设置res文件夹。需要指针来创建一个单一的代码库，...
