AndroidWearとAmazon API GatewayでGithub Follower数を見える化

この記事は公開されてから半年以上経過しています。情報が古い可能性がありますので、ご注意ください。

目的

様々なサービス上のAPIで取得できる数値データ等を一元的に管理した上でAndroidWearに表示したい。
新たに利用したAPIが増えたり、変更された時にメンテナンスコストを低く、セキュリティ面を担保した上でAndroid側のプログラムを簡単な物にするために今年の7月に使えるようになったAmazon API Gatewayを利用する。(日本リージョンはまだ未対応)

動作概要図

AndroidWearがインターネット上のデータを取得するには、親機を経由しなければならないため、親機でAmazon API Gatewayへアクセス -> Wearに取得したデータをmessageとして送信という全体像となります。

本来であればwear側から定期的にmobile側へ情報更新要求を出し、wear側へ送信や mobile側からnodeが存在すればwear側へ定期的に送信等処理を実装して完成に至ると思いますが、通信可能なWatchFace作成方法の情報が英語・日本語共に少なかったので、土台部分の実装のみひとまずデモ的に動いたので公開致します。

Amazon API Gatewayの利用

Android側のアプリケーションでHTTPリクエスト組み立てたり複数のAPI管理が面倒だな、、、と考えた時にAPIをまとめて管理出来て、Android/iOS/Javascript用のAPIアクセスライブラリ/SDKを吐き出してくれる「Amazon API Gateway」が頭をよぎりましたので利用してみました、ほんの触りでプロクシ機能しか使っておりませんが非常に短いコードで行けたので利用しない手は無いと思いました。

これまでイマイチ使い処が見えにくかった Lambda がAPI Gatewayとの組み合わせで色々使えるかなぁと感じております。下記を今後実施してみる予定、、、
API Gateway -> Lambda -> SNS -> Android端末等へ通知/Twilio 等々

Android Wearへのデータ送信

下記方法で mobile側から wearにデータを送信し WatchFaceを更新しています

mobile側処理

  • アプリ起動時にGoogleApiClientを利用可能にする
  • 通信可能な端末を getNodes で取得
  • GoogleApiClient の sendMessage で Wearにメッセージを送信

wear側処理

  • Messageを受信すると DataLayerListenerService の onMessageReceived が呼び出される
  • Preferencesに受信したメッセージ内容を書き込み
  • WatchFace の 描画部分でPreferenceより取得した値を表示

完成品

母艦でRefreshボタンを押すと、弊社の現在のgithub follower数がWatchFaceに表示されます

Android Studioでプロジェクトを作成

Mobile / Wear両方のチェックボックスを付けたプロジェクトを作成します。
2つのモジュールを跨ぐクラスの作成については、New Module -> Common等の名前で作成しdependenciesの設定を下記のように行います。
