1. Open the Android agent source code in Android studio.
   The event related logic is included in the org.wso2.emm.agent.events package. It has the following folder structure.
   [image of project structure to be added here]

2. Implement the AlertEventListener interface in the org.wso2.emm.agent.events.listeners package.

   Info

   Expand title Click here for more information on the methods used in the AlertEventListener interface. The following methods are used: startListening() - This method is used to start listening to an event broadcasted by the OS. In case of a polling based check, this method can be called by the onReceive method of the AlarmReceiver. stopListening() - Stop a receiver or an alarm can be done here publishEvent(String payload) - Publishing data to EMM can be handled here.

   Example:

   Code Block
   language java title AlertEventListener interface firstline 1 linenumbers true
   package org.wso2.emm.agent.events.listeners; /** * This is used to define any new events that needs to be captured and sent to server. */ public interface AlertEventListener { /** * This can be used to start listening to a specific broadcast receiver. * Another usage would be, when there is an event that doesn't do a broadcast. For example * Application exceeding 75% of CPU is not broadcasted by default from the Android OS. Only way * to catch it is by constantly polling a specific API and check for the status. In such a * situation, AlarmManager can call startListening on it onReceiver method to do the polling on * an API. */ void startListening(); /** * If in case, listening to a specific receiver need to be done here. This can be a place to, * stop an AlarmManager. */ void stopListening(); /** * This is where publishing data to EMM/DAS would happen. This can ideally be called from * an onReceive method of a BroadcastReceiver, or from startListening method to inform the * results of a polling. * * @param payload JSON string payload to be published. * @param type type of the alert being published. */ void publishEvent(String payload, String type); }

3. Capturing events. There are two ways to capture the events as listed below:
