How to Add Multiple Markers to Google Maps in Android using Jetpack Compose?
Google Maps is used in most apps which are used to represent many locations and markers on Google Maps. We have seen markers on Google maps for multiple locations. In this article, we will take a look at the implementation of Multiple Markers on Google Maps in Android using Jetpack Compose.
Step By Step Implementation
Step 1: Create a New Project in Android Studio
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. While choosing the template, select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version. We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project.
Step 2: Adding a new color to the Color.kt file
Navigate to app > java > your app’s package name > ui.theme > Color.kt file and add the below code to it.
Step 3: Adding Dependency to use Google Maps.
Navigate to build.gradle file and add the below dependency in the build.gradle file.
implementation("com.google.android.libraries.maps:maps:3.1.0-beta") implementation("com.google.maps.android:maps-v3-ktx:2.2.0") implementation("androidx.fragment:fragment:1.3.2")
After adding the dependency simply click on the sync now option to install it.
Step 4: Adding Permissions and Google Maps API key.
