My custom plugin not loading on android

[Abin]

I have written a plugin and I am trying to load it. It works fine when I debug in windows machine. But when I make the final package in android (not checked in windows) it fails to load the plugin. :(

@void MainFrame::loadPlugin()
{
qDebug()<<Q_FUNC_INFO<<"Invoked";
QDir pluginsDir(qApp->applicationDirPath());
qDebug()<<Q_FUNC_INFO<<"pluginsDir.dirName"<<pluginsDir.dirName();
#if defined(Q_OS_WIN)
if (pluginsDir.dirName().toLower() == "debug" || pluginsDir.dirName().toLower() == "release") {
pluginsDir.cdUp();
pluginsDir.cdUp();
pluginsDir.cd("plugins");
}
#endif
foreach (QString fileName, pluginsDir.entryList(QDir::Files))
{
QPluginLoader pluginLoader(pluginsDir.absoluteFilePath(fileName));
QObject *plugin = pluginLoader.instance();
if (plugin)
{
qDebug()<<Q_FUNC_INFO<<"plugin instance is loaded";
m_pServerInterface = qobject_cast<ServerInterface *>(plugin);
if (NULL == m_pServerInterface)
{
//error screen should be displayed.
qDebug()<<Q_FUNC_INFO<<"plugin object casted to ServerInterface is Null";
}
}
}

qDebug()<<Q_FUNC_INFO<<"loadPlugin() Exit";

}@

can someone help to find the mistake. I doubt in the path as for windows while debugging it works

QPluginLoader pluginLoader(pluginsDir.absoluteFilePath(fileName));
bool pluginLoaded = pluginLoader.isLoaded();

It gives me false..
