-  <h3 id="libraryMigrating">Migrating library projects to ADT 0.9.8 or higher</h3> 
- 
-<p>This section provides information about how to migrate a library project
-created with ADT 0.9.7 to ADT 0.9.8 or higher. The migration is needed only if
-you are developing in Eclipse with ADT and assumes that you have also upgraded
-to SDK Tools r7 (or higher). </p> 
- 
-<p>The way that ADT handles library projects has changed between
-ADT 0.9.7 and ADT 0.9.8. Specifically, in ADT 0.9.7, the <code>src/</code> 
-source folder of the library was linked into the dependent application project
-as a folder that had the same name as the library project. This worked because
-of two restrictions on the library projects:</p> 
- 
-<ul> 
-<li>The library was only able to contain a single source folder (excluding the
-special <code>gen/</code> source folder), and</li> 
-<li>The source folder was required to have the name <code>src/</code> and be
-stored at the root of the project.</li> 
-</ul> 
- 
-<p>In ADT 0.9.8, both of those restrictions were removed. A library project can
-have as many source folders as needed and each can have any name. Additionally,
-a library project can store source folders in any location of the project. For
-example, you could store sources in a <code>src/java/</code> directory. In order
-to support this, the name of the linked source folders in the main project are
-now called &lt;library-name&gt;_&lt;folder-name&gt; For
-example: <code>MyLibrary_src/</code> or <code>MyLibrary_src_java/</code>.</p> 
- 
-<p>Additionally, the linking process now flags those folders in order for ADT to
-recognize that it created them. This will allow ADT to automatically migrate the
-project to new versions of ADT, should they contain changes to the handling of
-library projects. ADT 0.9.7 did not flag the linked source folders, so ADT 0.9.8
-cannot be sure whether the old linked folders can be removed safely. After
-upgrading ADT to 0.9.8, you will need to remove the old linked folders manually
-in a simple two-step process, as described below.</p> 
- 
-<p>Before you begin, make sure to create a backup copy of your application or
-save the latest version to your code version control system. This ensures that
-you will be able to easily revert the migration changes in case there is a
-problem in your environment.</p> 
- 
-<p>When you first upgrade to ADT 0.9.8, your main project will look as shown
-in figure 1, with two linked folders (in this example, <code>MyLibrary</code> and
-<code>MyLibrary_src</code> &mdash; both of which link to
-<code>MyLibrary/src</code>. Eclipse shows an error on one of them because they
-are duplicate links to a single class.</p>

-<p>To fix the error, remove the linked folder that <em>does not</em> contain the
-<code>_src</code> suffix. </p>

-<code>MyLibrary</code> folder) and choose <strong>Build Path</strong> &gt;
