und tut plz mir sagen, die richtige Emulator Spezifikation zu tun ... es Fehler von Emulator sein kann ......Wie markererclusterer in Android mit beiden Karten apiv2 oder Karte api v3
Ich habe versucht, durch folgende Links

ich versuche, die app zu bauen, die Marker brauchen gruppierten, so habe ich versucht, so viele Male die Google API, um die Demo erstellen lesen, aber jedesmal, wenn es Fehler zeigt, machen sie mich auch, dass die Web-Anwendung verwendet map API v3 Clustering der Marker, welche API ich API v2 oder apiv3 der Karte verwenden, um eine App zu bauen bitte helfen Sie mir, ich bin Neuling bei Android oder mir etwas Link geben, wo ich meine Lösung
