I have been successful at adding the pins but I need the pins to be refreshed when the user clicks on the map and provides a new location, I get an error. Keep in mind that I need this to happen in the background so that it does not affect the map interaction.
My problem is that when the user clicks on the map the list of map pins is already being updated and I get an ConcurrentModificationException error.
Basically, I have a JSONArray which has locations. I need each location to be on the map and when the new location is touched the pins are updated and the old pins are cleared.
Any suggestions on how to make this more friendly and easier. I cannot seem to get rid of the ConcurrentModificationException error.
Here is the "the missing widget"...

I am trying to implement marker clustering in android in a repeated way i.e. locations are being fetched from sql server and points are placed on map. But the problem i am facing is that the markers newly plotted or updated are not shown itself, I have to zoom in or out to see the updated markers. I have used
mclusterManager.clearItems()
but still same thing is happening. Any solution??
You need to force a recluster after adding new items doing
mclusterManager.cluster();
I have to add multiple markers on map , and show their info windows at the same time .
When i add the last marker the previous info window markers automatically gets hidden.Can anyone tell me any solution how can i do this?
That is not possible with InfoWindows as noted by the 2nd sentence on this page. You might try using this library to instead put the text you would be displaying in the InfoWindow in the Marker itself. Be careful with showing too much information on the screen at once, don't want it to get too busy!
I have a google map in an android application, using API V2, and I've run into a slight problem. I'm loading all Markers in the visible map area from a database. That part is running fine, as is clicking them, and clicking their info windows.
The problem is, once I have the info window click event captured, I want to send the represented database object to another activity. How do I get that. I was thinking latlng of the marker, but it appears to have been adjusted/truncated when put on the map. So I was thinking of using the name of the building, but what if two buildings have the same name. I was thinking subclassing Marker and giving mine an id, but Marker is a final class.
For now I'm going to settle on a name/address kind of search, but I'd prefer something a little more definitive to the specific object the marker represents. How do I store extra data in a marker?
During the CameraChange event I add new markers to the map, so I want to know if they are removed automatically when they become invisible as the camera has moved.
Does anyone have this information?
Do you mean, are markers removed when the map is panned such that the marker is no longer on the screen? If so, the answer is no, the markers are still "on the map" even when "off screen".
If you would like to remove markers as they are moved off the map, please see my answer to this question
Recently I show the ubicabs taxi booking app. I found very nice functionality inside it. In this app they have google maps for showing markers, but they have used very good UI component for that. Also I found one more uniqueness is that whenever user moves or change the position of marker through touch it will fetch the current location. One thing that I know is that it is using the onTouchEvent of Overlay but how to create that marker balloon and how to get updated location on the basis of that marker.
I am attaching a preview of that marker here. Also would like to know that how can we scroll the text inside that balloon?
The best overlay open project I have found so far is this one, link. But it is nothing compared to the picture above. Would also like to know how they created this! Great Question and picture ;)
