Вопрос

Ok so I've searched and searched, I'm on the final hurdle of getting this example project working, but now it keeps failing to launch on my phone (Galaxy S4) when I try to implement android-maps-extensions 2.0 (I have loads to markers to add to the map, but need them dynamically)

I have the libraries all setup and working as they should, but whenever I change my MapFragment codes to SupportMapFragment the app crashes and doesn't open. If I leave everything as is the app loads on my phone fine

What am I doing wrong? I'm wracking my brains trying to figure this out. I have so many markers to add to the map I need the clustering abilities of the map extensions

Thank you

Это было полезно?

Решение

I have figured it out. I wasn't importing com.androidmapsextensions.SupportMapFragment in my layout file, I was importing com.google.android.gms.maps.SupportMapFragment hence the map wasn't loading.
