Ich habe eine PNR Anfrage App bei Google Play. Es hat sehr gut funktioniert. Aber vor kurzem hat Indian Railwys Captcha zu ihrem PNR-Anfrage-Bereich hinzugefügt, und aus diesem Grund kann ich keine richtigen Daten an den Server übermitteln, um eine angemessene Antwort zu erhalten. Wie füge ich dieses Captcha in meiner App in Form einer Bildansicht hinzu und fordere die Benutzer auf, auch die Captcha-Details einzugeben, damit ich korrekte Daten senden und eine angemessene Antwort erhalten kann.Wie aktualisiert man die PNR Capcha hinzugefügt in der Indian Railways Site
Indian Railways PNR Inquiry Link
Hier ist meine PnrCheck.java, die ich früher verwendet hat. Bitte helfen Sie, welche Änderungen sollten hier getan werden ..
