IDTECH Unimag kart Swiper na Androida

Question

pracuję na Android (v2.3) przez kilka tygodni, a ja natknęliśmy się na pewne problemy z Unimag kart Swiper od IDTECH.

Urządzenie ma ograniczoną dokumentację, a aplikacja demo SDK implementuje aktualizację oprogramowania i kilka klas dla dialogów oraz takie, które naprawdę zaciemniają sposoby uzyskania podstawowej funkcjonalności (dodane do niewielu i niezbyt dobrych komentarzy w kod).

Zaimplementowałem interfejs w podstawowej czynności i próbowałem wykryć, kiedy urządzenie jest podłączone lub odłączone, ale wydaje się, że słuchacz łapie oba zdarzenia (połączenie/rozłączenie) jako "rozłączenie", nie mówiąc już o próbie odczytu karty.

Czy ktoś pracował z tym urządzeniem na Androidzie i ma kilka wyraźnych przykładów?

Nawiasem mówiąc, tu jest moja klasa:

Answer 1

Oto, co kiedyś z UniMag. Za pomocą programu obsługi wyprowadzić przeskanowane dane i przycisk "Przesuń", aby rozpocząć przesuwanie. Aby to poprawić, należy poczekać, aż czytnik kart zgłasza, że ​​jest podłączony/gotowy do przesuwania, a następnie włączyć przycisk, wyłączyć podczas oczekiwania na przesunięcie i ponownie włączyć po otrzymaniu danych.

okazało się, że aplikacja 3,8 demo one dostarczane z SDK ma błąd, gdzie nie będzie łączyć się z Android tablet gt-p3113 chyba że idziesz do ustawienia w aplikacji na telefonie i wyłącz „Command Połączyć'.
