サンプルのクローンを作成して実行する
このサンプルをローカルで実行するには、Git が必要です。次のコマンドで、サンプルアプリ リポジトリのクローンを作成します。
git clone git@github.com:googlemaps-samples/android-samples.git
サンプル プロジェクトを Android Studio にインポートします。
- Android Studio で、[File] > [New] > [Import Project] を選択します。
リポジトリの保存先に移動し、Kotlin または Java のプロジェクト ディレクトリを選択します。
- Kotlin:
PATH-REPO/android-samples/ApiDemos/kotlin - Java:
PATH-REPO/android-samples/ApiDemos/java
- Kotlin:
- [Open] を選択します。Android Studio が Gradle ビルドツールを使用してプロジェクトをビルドします。
- プロジェクトの
local.propertiesファイルと同じディレクトリに空のsecrets.propertiesファイルを作成します。詳しくは、API キーをプロジェクトに追加するをご覧ください。 次の文字列を
secrets.propertiesに追加し、YOUR_API_KEY を実際の API キーの値に置き換えます。MAPS_API_KEY=YOUR_API_KEY- アプリを実行します。
