リスト ビュー用に BaseAdapter 拡張クラスを作成しました。
内部には、コードで設定したい TextView フィールドがあります。このフィールドは、ユーザーの Facebook ステータスを表します。
このフィールドは時々ヘブライ語のテキストを取得し、stackoverflow エラーでクラッシュします。
フィールドが取得するテキストが英語の場合、これは発生しないことを追加することが重要です。問題を見つけるためにデバッグしようとしたときに、アクティビティ内でヘブライ語の文字列を含む setText を使用しました (BaseAdapter ではありません)。それはうまくいきました。
これは私のクラスです：

私はコードが少し大量であり、スレッドとハンドラーの代わりに asynctask を使用する必要があることを知っていますが、これは単なるテストであり、機能するかどうかを確認したかったのです...
