私は Android Google Maps API の初心者で、API を使用して小さなアプリを開発しようとしていました。Google のドキュメント フォームhttps://developers.google.com/maps/documentation/android/を参照として使用し、すべての手順を慎重に実行します。ビルドしてデバイス (Android 2.3.6) にインストールすると、アプリがクラッシュします。すべての指示に従ってアプリに署名し、この特定のアプリの API キーを取得し、ドキュメントのすべての手順を数回試しましたが、良い結果は得られませんでした。誰かがこれを手伝ってくれますか?何か足りないものがありますか?ありがとうございました!
