יצירת עותקים מקודמים והרצה של הדוגמאות

כדי להריץ את הדוגמה הזו באופן מקומי, צריך Git. הפקודה הבאה יוצרת עותק (clone) של מאגר האפליקציה לדוגמה.

git clone [e-mail]:googlemaps-samples/android-samples.git

מייבאים את פרויקט הדוגמה ל-Android Studio:

1. ב-Android Studio, בוחרים באפשרות File (קובץ) > New (חדש) > Import Project (ייבוא פרויקט).

2. עוברים למיקום שבו שמרתם את המאגר ובוחרים את ספריית הפרויקט ל-Kotlin או ל-Java:

   • Kotlin: PATH-REPO/android-samples/ApiDemos/kotlin
   • Java: PATH-REPO/android-samples/ApiDemos/java
3. בוחרים באפשרות פתיחה. Android Studio יוצר את הפרויקט באמצעות הכלי ל-build של Gradle.
4. יוצרים קובץ secrets.properties ריק באותה ספרייה שבה נמצא קובץ local.properties של הפרויקט. מידע נוסף על הקובץ הזה זמין במאמר הוספת מפתח ה-API לפרויקט.
5. מקבלים מפתח API מהפרויקט שבו ה-SDK של מפות Google ל-Android מופעל.

6. מוסיפים את המחרוזת הבאה ל-secrets.properties, מחליפים את YOUR_API_KEY בערך של מפתח ה-API:

   MAPS_API_KEY=YOUR_API_KEY

7. מפעילים את האפליקציה.
