This guide is a quick start to adding a map to an Android app. AndroidStudio is the recommended development environment for buildingan app with the Maps SDK for Android.
Step 1. Download Android Studio
Follow the guides to download and installAndroid Studio.
Step 2. Install the Google Play services SDK
Add Google Play services to Android Studio.
Step 3. Create a Google Maps project
Follow these steps to create a new app project including a map activity:
Android Studio starts Gradle and builds your project. This may take a fewseconds. For more information about creating a project in Android Studio,see the Android Studio documentation.
When the build is finished, Android Studio opens the
google_maps_api.xml andthe MapsActivity.java files in the editor. (Note that your activity may havea different name, but it will be the one you configured during setup.) Noticethat the google_maps_api.xml file contains instructions on getting aGoogle Maps API key before you try to run the application. The next sectiondescribes getting the API key in more detail.
Step 4. Get a Google Maps API key
Your application needs an API key to access the Google Maps servers. The type ofkey you need is an API key with restriction for Android apps. The key isfree. You can use it with any of your applications that call theMaps SDK for Android, and it supports an unlimited number of users.
Choose one of the following ways to get your API key from Android Studio:
Step 5. Hello Map! Take a look at the code
Examine the code supplied by the template. In particular, look at the followingfiles in your Android Studio project.
The XML layout file
By default, the XML file that defines the app's layout is at
res/layout/activity_maps.xml . It contains the following code:

By default, the Java file that defines the maps activity is named
MapsActivity.java . It should contain the following code after yourpackage name:
If your maps activity file doesn't contain the above code, replace the contentsof the file with the above code, after your package name.
Step 6. Connect an Android device
The simplest way to see your app in action is to connect an Android device toyour computer. Follow the instructions to enable developeroptions on your Android device and configure your application and systemto detect the device.
Alternatively, you can use the Android Emulator to run your app. Use theAndroid Virtual Device (AVD) Manager to configure one or morevirtual devices which you'll be able to use with the Android Emulator whenyou build and run your app. When choosing your emulator, ensure that you useAndroid 4.2.2 or higher, and be careful to pick an image that includes theGoogle APIs, or the application will not have the requisite runtime APIs inorder to execute. Also, take note of the instructions forconfiguring virtual machine acceleration, which youshould use with an x86 target AVD as described in the instructions. Thiswill improve your experience with the emulator.
Step 7. Build and run your appDownload Country Google Maps For Android Car Stereo Navigation Systems
