Merge "docs: studio revision 21 update" into lmp-docs

            <li>Added a flag that sets <em>jumbo mode</em> for DEX files, which allows a larger

              number of strings in the DEX files. Enable this mode by adding the following line to

              the {@code project.properties} file of your project:

              <pre>set dex.force.jumbo=true</pre></li>

              <pre>dex.force.jumbo=true</pre></li>

            <li>Improved the build time by pre-dexing libraries (both JAR files and library

              projects).</li>

            <li>Updated the build to generate {@code R} resource classes for library projects
