到達不能コード Home.java /idg/src/com/idg/omv 行 104 Java 問題
104 行目に到達不能コードを示すエラーが表示されます。これは次のとおりです。
youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtubeplayerview);
なぜこれが起こっているのか、それを解決するために何ができるのか正確にはわかりません (これまでに遭遇したことはありません)。私が読んだことから、コードの一部が範囲外にあることに問題があるようです。問題を解決する方法がわかりません。（いくつかの}を追加しようとしましたが成功しませんでした）
