android - Google Maps Android API v2 に関する問題

Question

Google マップ API の動作を調べるために、サンプル アプリケーションを実装しようとしています。私は構成自体に感銘を受けました。アプリケーションを実行できないようです。

これがGithubの私のコードです:-

https://github.com/siva54/SampleMapApplication

そして、ここに私のlogcatがあります:-

助けてくださいませんか？前もって感謝します。

Answer 1

実行時に Google マップのクラスが見つからないようです。現時点ではエミュレータで Google マップ v2 を使用できないため、これをデバイスまたはエミュレータで実行していますか。

デバイスで実行している場合は、Google Play Services がインストールされていることを確認してください。これには、Google マップ v2 のランタイムが含まれています。

Answer 2

私の問題を解決しました。問題が発生したのは、Google Play ライブラリを参照したにもかかわらず、参照が Eclipse によって考慮されず、クロス マークで表示されたためです。次のstackoverflow投稿の助けを借りて解決しました：-

Eclipse では、別の Android プロジェクトで Android ライブラリ プロジェクトを参照できません
