Adding Custom Mobile Device Rule Handlers in Liferay 6.1

Adding custom mobile device rule handlers in Liferay 6.1 enhances mobile support and customization. This guide walks you through creating a custom rule handler, starting with setting up a liferay-hook.xml file and configuring the portal properties. By following these steps, you can efficiently implement custom mobile device rules tailored to your needs.

In Liferay 6.1, one of the new built in features are the Mobile Device Rules. To add a custom rule handler, it’s fairly simple. You need to create a hook with the following liferay-hook.xml:

<?xml version="1.0"?>

<!DOCTYPE hook PUBLIC "-//Liferay//DTD Hook 6.1.0//EN"
 "http://www.liferay.com/dtd/liferay-hook_6_1_0.dtd">

<hook>

     <portal-properties>portal.properties</portal-properties>

</hook>

application.startup.events=com.xtivia.CustomRuleHandlerStartupAction

package com.xtivia;

import com.liferay.portal.kernel.events.ActionException;

import com.liferay.portal.kernel.events.SimpleAction;

import com.liferay.portal.kernel.mobile.device.rulegroup.RuleGroupProcessorUtil;

public class CustomRuleHandlerStartupAction extends SimpleAction {

    private static CustomRuleHandler _customRuleHandler = new CustomRuleHandler();

    public void run(String[] ids) throws ActionException {

        RuleGroupProcessorUtil.registerRuleHandler(_customRuleHandler);

    }

}

The CustomRuleHandler class needs to implement the com.liferay.portal.kernel.mobile.device.rulegroup.rule.RuleHandler interface, and the default implementation is contained within the com.liferay.portal.mobile.device.rulegroup.rule.impl.SimpleRuleHandler class.
