I am having trouble organizing my markers. I have a bunch of them, and the problem is that there are so many markers close to each other. Making it impossible to navigate using such polluted map.
Is there a way to cluster all those markers or any other way to make it less polluted? I have made a search around Mapbox's website, and thanks to a developer, I have found a way to implement such method, but any of those can be used with markers added within the map ( mapboxMap.addMarker() )
Example:
Data Clusters.
Does anyone know how to organize such markers? Thanks!
#Sem you could create a cluster of markers by using method setClusteringEnabled. I also faced same issue, this method is not supported in current mapbox sdk. I am using 4.0.
Try this Mapbox plugin. This lib has DefaultClusterRenderer.java class, you need to use it or implement ClusterRenderer.java interface, for drawing your own icons

I use the util library maps android for Cluster item.
I have many marker but It's too slow on navigation.
Is there a way to optimize this apps?
You can see this video : https://youtu.be/lboDrBmI6xo
Here are suggestions to Optimize Maps with Many
Makers:
One approach at simplification is to render markers on the server. Google provides two services built into the API that make this easy to
achieve: FusionTablesLayer and KmlLayer. If you'd prefer to perform
computations on your own server, this can be accomplished by creating
a custom overlay from imagery that is pre-rendered, or rendered on the
fly.
Another useful optimization technique involves viewport marker management: restricting the markers rendered on the map into only
those that exist within the viewable area.
If you still want to display many markers on the map, consider creating a custom overlay that displays markers with minimal
functionality. This approach may garner performance improvements over
standard markers provided by the API.
Read more on the docs for optimization tips.
I believe that marker clustering is the way to go on Android and we have a utility library to use for this. You can check it out here
I have a lot of points to show on Google Maps Android. I decided to draw them on the map by drawing circles with small radiuses. However, I noticed that drawing a lot of circles (around 1000) is very slow and the app does not respond well, even when the drawing is made in an AsyncTask.
Any ideas how to get around this?
The best way is to only plot what you can see on the map and when the map moves get the new points you can see so that you eventually dont have to plot anymore.
You can also look into clustering where if you have a bunch of markers in a certain area you can indicate a group of markers by just plotting one marker
this link goes over the different method you can use
https://developers.google.com/maps/articles/toomanymarkers
Consider using Markers instead and one of the clustering libraries freely available:
Android Maps Extensions
Clusterkraf
Android Maps Utils
If you are convinced you want to use Circles, you may try to use one of the libs and modify code to group Circles.
I'm making an app for android and I'm using an android map to show about 15k markers from a WebService, the map gets really slow, I have searched around and find a solution "Clustering" but I can't implement it in my app, my map is running with the lib "Polaris 2" and I tried "ClusterKraf", but I had no results.
If someone has a better way to show the markers or some way to make clustering please help me.
I have been using Android Map Extensions and Clusterkraf, but finally decided implement the clustering by my self. The clustering could be written in a very simple way and you could get more control in how the elements are showing in the map, etc.
You can read my implementation of clustering in http://arnaldog.wordpress.com/2013/07/31/simple-clustering-with-android-maps-v2/.
I hope that helps you.
Polaris 2 does not have clustering implemented.
Both Clusterkraf and Android Maps Extensions mentioned by iaindownie have demo app on Google Play, which are also open source, so you can download the code from their project sites to try working solution. Then you can copy relevant code into your project.
We added about 200 new markers in the MapView.
Now the app stucks and you cant use the MapView.
I heared about MarkerClusterer but did not found any more inforamation how to use MarkerClusterer with Android...or are there better solutions?
Can anyone give me a link or write a little turorial?
Thanks :)
You can have a look at this example Android project https://github.com/igorab/ManyPinsProject
It shows limited amount of markers depending on MapView zoom level.
Here is tutorial from Google https://developers.google.com/maps/articles/toomanymarkers
As #CommonsWare said it is only for JavaScript version or GoogleMaps, but may be you can find something useful there. For example, they have a link to MarkerClusterer js source code. Maybe you can find a way to adopt it to Android.
You can use this library – Android MapView Balloons. This project provides an easy way to annotate map overlay items with a simple information balloon when using the Android Maps.
I am wondering about the correct approach or maybe the difference between the following if my intention is to put 2 markers on the map and maybe remove them after a while.
Should I use the overlays to put them, or should I use the canvas.draw (or just draw) to put them or simply add the two images as a view and using the layout param I can set the location. I found the last one being the easiest but I need your input
Thank you.
Don't be surprised, this is a terrible question. Other than your two tags, you don't explain anything about the platform you're building on.
If you're building an Android app, you'd probably want to use the maps Overlay.
http://code.google.com/android/add-ons/google-apis/reference/com/google/android/maps/Overlay.html
If you're building a web app, I would use the Google Maps Javascript API Marker.
http://code.google.com/apis/maps/documentation/javascript/overlays.html#Markers
If you're not using either, or are not using Google Maps, I have no clue how you expect people to read your mind over the internet.
