そして、以下はSettings.xmlのコードです。
上記のコード全体は、Android 4.4.4エミュレータとデバイスでも正常に動作します。
質問を編集し、Javaスタックトレース全体を投稿することをお勧めします。また、サードパーティの設定を一時的にコメントアウトし、その中の1つが問題の原因であるかどうかを確認することをお勧めします。 – CommonsWare
はいすべてのライブラリを削除してチェックしても、まだコードが機能していません。完全なスタックトレースを更新します。 –
'org.jraf.android.backport.switchwidget.SwitchPreference'と' com.iq.android.preferences.AboutDialogPref'は有効なクラスですか？パッケージ名を再確認してください。 – azizbekian
