In Google Maps, I would like to be able to keep the center of the map on a marker on my location when I\'m zooming in or out. It\'s something that Ingress does, it doesn\'t matt
I have no idea why you tagged this question as both Javascript and Android. On Android you need to wrap your MapView inside another view and detect Double Tap motion inside onInterceptTouchEvent which you can override if your class can override FrameLayout for example. Then return true to prevent the map from handling this event and you handle it instead.
