• 情況：所以我調試並發現我在使用的第一個api調用

  HttpClient httpclient = new DefaultHttpClient();

  下一步是 AsyncTask public AsyncTask(@Nullable Looper callbackLooper) { 的 catch 塊並顯示上面的錯誤

  但是當我在 Android sdk 版本低於 28 ie 27 的其他設備上嘗試時，它工作正常，沒有錯誤

  在此先感謝您的幫助

您必須在清單文件中添加這些行

<uses-library android:name ="org.apache.http.legacy" android:required ="false"/>
