Mastering Map Markers in Android Studio: Adding Your Current Location

However, if you're new to Android Studio, you might face challenges, especially when trying to add a marker to show your current location. Don't worry! In this post, we'll guide you through the process of adding a marker to your location on a Google Map in an Android application.

The Problem: Displaying Your Current Location

This issue could stem from a variety of reasons, such as user permissions, incorrect coordinates, or improper map initialization.
