Call the createTimerEvent to start timing for an event. Configure the name of the event, and event properties to report. When the event comes to an end, a "_duration" property will automatically be added for this event (unit: millisecond). It should be noted that there can only be one timing task for the same event.

Step 1: Create Duration Event

Function

ppublic synchronized TrackEvent createTimerEvent(String eventName, JSONObject eventData);

Returned value: "trackEvent"

Sample Code

import com.reyun.solar.engine.SolarEngineManager;
import org.json.JSONObject;

JSONObject eventData = new JSONObject();
try {
    //Custom event properties in JSON format.
    eventData.put("key1","value1");
    eventData.put("key2","value2");
  ......
} catch (JSONException e) {
///
}

TrackEvent trackEvent = SolarEngineManager.getInstance().createTimerEvent("xxxCustomEventNamexxx", eventData);

Step 2: Report Duration Event

Function

public synchronized void trackTimerEvent(TrackEvent trackEvent);

Sample Code

import com.reyun.solar.engine.SolarEngineManager;

//The trackEvent here is obtained by creating duration event calling createTimerEvent method.

trackEventSolarEngineManager.getInstance().trackTimerEvent(trackEvent);

Note:

       When reporting the preset event _appEnd, the duration starting from the last _appStart will be reported by default. That is, the duration of an exit event does not need to be configured to start timing, and will be assigned a value by default.
