、それは私に白い画面を示し、その後、アプリがクラッシュして上記の言及例外は私がfragmentとを使用していレイアウトに見られるようなポイントまたsetContentView(R.layout.activity_main);

に当たっlogcatに示し私はすでにそれに取り組んでいたので私はそれを使用しました。

私は問題を理解しようとしましたが、それを行うことはできませんでした。 ご協力いただければ幸いです。

はあなたのマニフェストファイルにこのタグを配置する必要が

<meta-data 
     android:name="com.google.android.geo.API_KEY"
