This opens up several possibilities for anybody looking to create an application on Android.</p> <p>The implementation, even though is an initial early push, has a robust infrastructure. Here's an initial analysis and outline of the implementation:</p><ul><li>The implementation, quite similar in nature to Struts (and he's inspired by Struts for the same), has a front controller and implements Command Pattern.</li><li><a target="_blank" href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=blob_plain;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/controller/Controller.java;hb=8b0b074">Controller</a> is implemented as <a target="_blank" href="http://developer.android.com/reference/android/app/Application.html">Application</a> specialization that does all housekeeping.</li><li>Command is modeled using <a target="_blank" href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=blob_plain;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/command/ICommand.java;hb=8b0b074">ICommand</a> interface. Noting that a large part of the commands will be network, database, file-system or related operations that may take a long time to complete, it provides response using callback listener for asynchronous implementation</li><li>All commands are managed using <a target="_blank" href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=blob_plain;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/command/CommandQueueManager.java;hb=8b0b074">CommandQueueManager</a> which internally is managed using a simplified <a href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=blob_plain;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/command/ThreadPool.java;hb=8b0b074" target="_blank">ThreadPool</a> of <a href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=blob_plain;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/command/CommandThread.java;hb=8b0b074" target="_blank">CommandThread</a> instances.<br /> </li><li>The public interface of interacting with this complex infrastructure is <a href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=blob_plain;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/command/CommandExecutor.java;hb=8b0b074" target="_blank">CommandExecutor</a>, internally made use of by the Controller.</li><li>Modeling request, response and listeners are available in the package <a href="http://android-mvc.git.sourceforge.net/git/gitweb.cgi?p=android-mvc/android-mvc;a=tree;f=android-mvc/codebase/eclipse/src/com/mastergaurav/android/mvc/common;h=56ab2edff67b4514860e3850d3895446b7ea5cbf;hb=8b0b074" target="_blank">com.mastergaurav.android.mvc.common</a>.</li><li>To keep developer use extensible, input-commands and output-activities, they are purely numeric in nature.</li></ul><p>Keep a close watch on the project... holds good potential!</p> Eduzine© gvaish@edujini.com (Eduzine) Android 2010-08-15T20:22:27Z http://eduzine.edujini-labs.com/wfwcomment.php?cid=39 0 http://eduzine.edujini-labs.com/rss.php?version=1.0&type=comments&cid=39
