Android cocos2d-x プロジェクトで build_native.sh を実行すると問題が発生します。リンクの問題であることが判明しました。私が作成した cpp ファイルはコンパイルされていないため、未定義の参照になります。
エラーは次のとおりです。

Classes フォルダーの Android.mk ファイルに作成したすべての cpp ファイルを一覧表示する必要があると言う人もいます。しかし、Classes フォルダーを見てみると、そこには Android.mk がありません。では、どうすれば .cpp ファイルを一覧表示できますか?
アップデート ：
jni フォルダに android.mk ファイルがあることは知っています。しかし、そこにすべてのゲーム cpp ファイルをリストしても、cpp はまだ build_native プロセスでコンパイルされていません。したがって、cpp ファイルを一覧表示する方法がまったくわかりません。
