そして、ここでは私のGradle輸入している私の活動のコードです：私は、アップロード・ボタンを押すと、しかし、私はこのエラーを取得しますインターネット上での解決策はありません。誰かにアイデアはありますか？

Answer 1

これは実際には例外として、クラスローダーはクラスを検出していません。私はいくつかのことを提案することができます：

1. 閉じるプロジェクトを閉じてスタジオを開いてもう一度やり直してください。

2. あなたのアンドロイドインストールで実際にorg/apacheなどがあるかどうかを確認してください。 jarファイルがある場合は、jar tvf whatever.jarを使用してコンテンツをリストできます。長いリストになるので、jar tvf whatever.jar | grep apache
