Currently you are launching your activity on single click of marker using the onMarkerClick api. In it why dont you use a timer mechanism, which will record the number of clicks. You can do it in following steps

1. Record time on click & id of marker.
2. Whenever you get click event on marker. Check if ID is same as previous one and also the time between both events is less than some threshold.
3. If yes, Launch your activity.
4. If No, clear the saved id to new one and record time as well.
