The correct way to solve this problem is by updating Android Support Libraries in all relevant projects and library projects. In my case I've used Android support library and also one of the library project to implement my application. When I update both libraries, the problem solved. The way of updating Android support library is;

<ul>
<li>Right click on the project</li>
<li>Select Android Tools from the pop up window</li>
<li>Select Add Support Library </li>
</ul>

I solved this by removing appcompact from project, and changing in styles to

<pre><code>&lt;style name="AppBaseTheme" parent="Theme.Sherlock"&gt;
</code></pre>

Gradle Resource Merger merges all resource folders from all dependencies and place into single folder. In case there are duplicates build process will fail.

Fortunately, if you look below under Output: label, you will find the right path to the problem.

Here is an example 

<img src="https://i.stack.imgur.com/xUhb0.png" alt="enter image description here">

in your case it is 
<code>android-support-v7-appcompat\res\values\attrs.xml:476: error: Attribute "attributeName" has already been defined
</code>

You can also build your project from command line and get the right path.
attributeName
Inside <code>values\attrs.xml</code> file on line 476 you would find a with property named "attributeName". Most probably it is your own styleable that you have to change to get rid of the duplicate. 

So now, when you know the reason, you can locate that property in your project module and replace it with different name.

I'm using android-support-v7-appcompat as a library in my Android project. Now I want to include actionbarsherlock as another library project. When I add the second library, it gives so many errors like below

<pre><code>android-support-v7-appcompat\res\values\attrs.xml:476: error: Attribute "attributeName" has already been defined
</code></pre>

By changing one attribute value and it's related code snippet is a one solution that I've tried. But when there are nearly 80 lines like above, it will get a messy. Is there any other way I can solve this issue?

error: Attribute "***" has already been defined when using two library projects in Android

我正在使用android-support-v7-appcompat作为我的安卓项目中的一个库。现在，我想将actionbarsherlock作为另一个库项目包含进来。当我添加第二个库时，它给出了很多错误，如下所示android-support-v7-appcompat\res\values\attrs.xml:476:...
