I just re-tested cluster marker example and it works fine.

Do you use the latest Mapsforge code?

get code from Githab  0.7.0 vs SNAPSHOT!!

get from GitHub
 

[Emux]

Tested Samples snapshot on Android 7 & 5, all seem work fine.

Are the other Samples examples working?

[Naser Bagheri]

get code from github (https://github.com/mapsforge/mapsforge/archive/master.zip) and import the android Studio

[Naser Bagheri]

Problems remain!!

[Emux]

We have test it in devices and emulator with various Android versions and the Samples example works.

Any additional information about your testing environment?

Do the rest Samples examples work correctly?

problem solved
geopoint coordinates Outside of range map file !!
Thank you

[Peter Storch]

I stumbled upon the same problem. Maybe because I start the Map at LatLon 0, 0 and my GeoItems were far away.

I've created an issue for it and send a patch PR.
