アンドロイドでwekaライブラリを使用する際のエラー

Question

Androidアプリケーションで機械学習を実装するために、私はこれをプロジェクト 'libs'に含めてコンパイルする 'WEKAツール'を使用していますそれはプロジェクトの 'gradle'からです。

しかし、その関数が呼び出されて（「RandomForest Classifier」を呼び出す）関数を呼び出したときに電話が実行されているときに、アプリケーションがクラッシュします。

「ランタイムエラー」が発生しました。誰も私を助けることができますか？

、このいずれかを使用してみてください：https://github.com/rjmarsan/Weka-for-Android

ライターが言うように：100％の機能が約束されていません。しかし、それは何もないよりも確かに良いです。
