הדוגמה הזו מזהה מיקום במפה באמצעות סמן מתקדם, וממחישה חלק מהיכולות של סמנים מתקדמים.
מידע נוסף זמין במסמכי התיעוד.
תחילת העבודה
כדי שתוכלו לנסות את הקוד לדוגמה, עליכם להגדיר את סביבת הפיתוח. מידע נוסף זמין במאמר SDK של מפות Google לדוגמאות קוד של Android.

שכפול והרצת הדוגמאות
יש צורך ב-Git כדי להריץ את הדוגמה הזו באופן מקומי. הפקודה הבאה משכפלת את מאגר האפליקציות לדוגמה.
git clone git@github.com:googlemaps-samples/android-samples.git
ייבוא של הפרויקט לדוגמה אל Android Studio:
- ב-Android Studio, בוחרים באפשרות קובץ > חדש > ייבוא פרויקט.
נכנסים למיקום שבו שמרתם את המאגר ובוחרים את ספריית הפרויקט עבור Kotlin או Java:
- Kotlin:
