1Google Map Markers Ekleme Sorunu
Merhaba arkadaşlar,
Geliştirmekte olduğum bir projede harita üzerine marker ekleme problemi yaşıyorum. Web service de sıkıntım yok gayet düzgün bir şekilde çalışıyor.Android kısmında bir sorun olup olmadığından emin değilim.Harita üzerinde markerları bir türlü gösteremiyorum. Yazdığım kod aşağıda.Yardımcı olursanız sevinirim.
