From Android Studio, I created a Map Activity project; so, there's no custom code.
The only custom changes made was copying the URL from the google_maps_api.xml _(https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=)_ and using it to create an API key.
Android Studio: 3.0.1 Emulator: Nexus 5X with API 25
apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' android { compileSdkVersion 26 defaultConfig { applicationId "xxxx.xxx.xxxx" minSdkVersion 19 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.google.android.gms:play-services-maps:11.0.0' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' }
It seems like I'm missing something; I just don't know what it is.
Try to run in your mobile. Sometimes emulator is not able to load map properly, That's why it shows blank map without loading roots.
