Added minZoomLevelVisible to MarkerOptions, which works as follows: For Markers with ClusterGroup.NOT_CLUSTERED, MarkerOptions.minZoomLevelVisible(float) can be set to hide markers when map is below the specified zoom level and show markers when map is above the specified zoom level.

Added support for Marker zIndex, introduced in Google play services maps 9.2.0.

Breaking changes

• Removed getExtendedMap() as getMap() is not any more available in Google play services sdk
• minSdkVersion is now 9

Hi!

Now your project is mavenized, it would be great to publish your artifacts to the central repository! This would allow us to use your library more easily :)

What do you think about that ?

If I use 'com.google.android.gms:play-services:9.4.0' the project will not run. The following exception will be thrown:

java.lang.AbstractMethodError: abstract method "com.google.android.gms.maps.GoogleMap com.androidmapsextensions.MapHolder$Delegate.getMap()"
            at com.androidmapsextensions.MapHolder.getExtendedMap(MapHolder.java:27)
            at com.androidmapsextensions.SupportMapFragment.getExtendedMap(SupportMapFragment.java:44)

Using an older version like 'com.google.android.gms:play-services:3.2.65' it runs fine.

Hi,

First, thank you for your library, it's really useful !

Since 2.3.0, I'm receiving some crashes from this library on Crashlytics :

Fatal Exception: java.util.ConcurrentModificationException

I'm using version 10.0.1 from play-services-maps

Great library, much quicker than the Google one.

Slight problem though - I'm adding ~16,000 markers relatively slowly while moving around the map, zooming etc.

After not very long some of the clusters will remain with a very high number of markers but zooming in all the way it will stay the same. If I tap one of these clusters it fires the method to get the info window: public View getInfoContents(Marker marker) {}

However the marker that is passed is null.

At the very least is there a way to force the map to re-group all the markers to remove these wrong ones?

Hi Maciej,

I tried to update my google play services to 6.5.+ to use granular dependency management. But I get this error:

It appears when trying to inflate com.androidmapsextensions.SupportMapFragment. Any ideas?

Btw, it's a great library. Are you planning to develop it further in spite of native support for clustering?

• update Google play service to most recent
• update Gradle tools version With this commit, developer are no more forced to change AME when we use it as git submodule and want update libraries

Great job with this library - it works great!

I've found a need to extend the GridClusteringStrategy and was hoping to somehow configure the library to use the subclass without modifying the library, Perhaps through the ClusterOptions interface.

So first, is it correct that it is not possible currently to provide a custom ClusteringStrategy through the client interface. And second, if not then would this be a reasonable approach (through the ClusterOptions)?

The reason I've found to extend GridClusteringStrategy is programmatic showInfoWindow does not work as expected - keeps getting ignore in onShowInfoWindow in GridClusteringStrategy.

Comments welcome.

It is very happy to find Android-Maps-Extensions,which is the thing I need to use in my project.However, I found some issues during running.

When I have try to use Android-Maps-Extensions-Demo from version 1.0 to 1.6 on handphone debugging model, it can run on the Android device that Android version is 4.1.2(Android API 16) or above ,but it can not be run on Android device that Android Version is below 4.1.2(API level 16) like Android 4.0.4, Android 4.0.3 and so on.

Moreover, I try to run on AVD ,and result is same as debugging model.

Hence, I want to confirm whether Android-Maps-Extension library and demo only can run on Android 4.1.2 & above? If not, do you know what happen?

Thank you very much

It looks like the maintainer has lost his interest at all, because all my pull requests are unmerged.

But helping myself, I made my fork up do date.

It contains Android X, most recent build tools Android Studio 3.5 and several additional improvements.

You can use it with

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

dependencies {
    implementation 'com.github.hannesa2:android-maps-extensions:$latest'
}

• This PR adds getOriginalMap() getter to this lib GoogleMap interface, which returns original GoogleMap (com.google.android.gms.maps.GoogleMap)
• With help of this new function, you can use this library with other Google Maps libraries which requires original Google map like android-maps-utils

If I use clustering together with marker animation - I often encounter an issue where I zoom enough for cluster to split but it doesn't. When that happens - no matter how close I zoom or pan, clusters keep just stuck in their latest positions

I've tried calling map.setClustering(null) after having this happening to see if clusters at least get cleared, but it doesn't help.

If I don't use marker animation - this doesn't happen.

Looks like timing issue / race condition to me.

Google APIs has been updated on April 10th to version 15.0.0 and, as stated in release note :

All references to com.google.android.gms.R classes have been replaced by component specific references; for example, com.google.android.gms.ads.R. If you use these classes directly in your code, you may need to update your code to be compatible. (Source)

Could you please update references to meet these requirements ? Thanks

First of all thank you for this library. I have been able to flawlessly add more than 5000 markers on the map. Yet, when I rotate the device, I have a memory leak. I changed the code to use only the googlemaps one without the elements of AME and I didn't have any memory leak while rotating the screen (yet I can't add that more markers with such fluidity). Here is the Java Heap Dump capture:

When I make a right click and jump to source it brings me here:

private class DelegatingOnCameraChangeListener implements com.google.android.gms.maps.GoogleMap.OnCameraChangeListener {

        @Override
        public void onCameraChange(CameraPosition cameraPosition) {
            markerManager.onCameraChange(cameraPosition);
            if (onCameraChangeListener != null) {
                onCameraChangeListener.onCameraChange(cameraPosition);
            }
        }
    }

Keep in mind that in the destroy view of the mapview I use this (to make sure every thing is cleaned) :

if(googleMap != null) {
            googleMap.setOnMapClickListener(null);
            googleMap.setOnMarkerClickListener(null);
            googleMap.setInfoWindowAdapter(null);
            googleMap.setOnCameraChangeListener(null); // <--
            googleMap.setOnGroundOverlayClickListener(null);
            googleMap.setOnCameraMoveCanceledListener(null);
            googleMap.setOnCameraMoveListener(null);
            googleMap.setOnCameraMoveStartedListener(null);
            googleMap.setOnCircleClickListener(null);
            googleMap.setOnMyLocationChangeListener(null);
            googleMap.setOnMapLongClickListener(null);
            googleMap.setOnInfoWindowClickListener(null);
            googleMap.setOnInfoWindowCloseListener(null);
            googleMap.setOnInfoWindowLongClickListener(null);
            googleMap.setOnPoiClickListener(null);
            googleMap.setOnPolygonClickListener(null);
            googleMap.setOnPolylineClickListener(null);
            googleMap.setClustering(null);
        }

Here is the version that I currently use:

compile 'com.google.android.gms:play-services-maps:9.8.0' compile 'com.androidmapsextensions:android-maps-extensions:2.4.0'

1- Is there anyway to fix that memory leak from the library side? 2- For all your handlers, can you use this, that uses weak references for its handlers to avoid any memory leak?
