Android Jetpack Compose: How to Use Google Maps
Many applications such as Swiggy, Zomato, ola, and others use Google Maps within their application to display the location within their application. Most of these applications use Google Maps to display the details within their application. In this article, we will take a look at How to integrate 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 in 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.
