Google Maps Android API V2 LocationSource vardır. Dokümanlar:
"Bir GoogleMap nesne benim konum katmanı için yerleşik bir konum sağlayıcı var, ama bu arayüzü uygulayan bir başkasıyla değiştirilebilir"
LocationSource
Bunu çözdü bir LocationSource.OnLocationChangedListener

ile birlikte kullanan gerekir düşünün. Eğer runOnFirstFix benzer bir şey yapmak istiyorsanız, burada Kullanıcının konumu hazır olana kadar, daha sonra bulundukları yere konumlandırmak için haritayı animasyon bekler temel bir örnek. konumlarını ekranın dışına gittiğinde kullanıcının konumuna haritayı ortalama ilgileniyorsanız (MyLocationOverlay eski API yaptığı gibi)
