MainActivityクラスが保存されているのと同じパッケージに記述した別のクラスを呼び出しています。しかし、アプリケーションを実行すると、java.lang.NoClassDefFoundError. 同じパッケージで定義された別のクラスを識別できない理由がわかりません。提案する多くの方法を試しましjava.lang.NoClassDefFoundErrorたが、いずれもエラーを解決しませんでした。

アップデート：

エラーの原因が見つかったと思います。その例外を作るのは、クラス内で使用したライブラリです。クラス内でhttpclient-4.2.5.jar、jackson-core-2.2.0.jar、json-lib-2.4-jdk15.jar、json-simple-1.1.1.jar、およびrt.jarを使用しています。例外を発生させずにこれらのライブラリを使用できる方法はありますか?
