Hiding API keys in local.properties

1. Add the API key to your local.properties file:

apiKey=<value>
serverKey=<value>
mapKey=<value>

2. Add to the root level of your app-level build.gradle file:

def localProperties = new Properties()
localProperties.load(new FileInputStream(rootProject.file("local.properties")))

3. Add to the android { defaultConfig { } } block of your app-level build.gradle file:

android {
    // ...
    
    defaultConfig {
        // ...
        buildConfigField "String", "API_KEY", localProperties['apiKey']
        buildConfigField "String", "SERVER_KEY", localProperties['serverKey']
        buildConfigField "String", "MAP_KEY", localProperties['mapKey']
    }
    
    // ...
    
}

4. Sync Gradle and build the project. You can now reference the key:

val apiKey = BuildConfig.API_KEY
val serverKey = BuildConfig.SERVER_KEY
val mapKey = BuildConfig.MAP_KEY

String apiKey = BuildConfig.API_KEY
String serverKey = BuildConfig.SERVER_KEY
String mapKey = BuildConfig.MAP_KEY

Please update this file for Kotlin too
