將ZXing項目導入到Ubuntu上的Android Studio中

Question

我對Android開發非常陌生。我只是設置了環境並使用Android Studio。 如上所述;

Integrate ZXing in Android Studio

我已經進口了斑馬線-2.3.0項目到Android Studio中，並加入核心3.1.0.jar作爲庫的項目，但是當試圖建立的項目，我仍然得到下面的錯誤消息。可能是什麼問題呢？

Answer 1

這些都是非常古老的說明。項目文檔可能會有更多幫助。 https://github.com/zxing/zxing/wiki/Getting-Started-Developing您應該使用最近的版本，而不是2.3。

我不清楚你想要做什麼。在這裏，你已經下載了源代碼，並試圖直接打開它作爲一個項目。這個錯誤意味着它說：你沒有設置你的項目來依賴庫中的任何庫，比如Android。相反，你應該已經導入了Maven構建。

但是你說你正在添加核心.jar文件，但是來自完全不同的版本3.1.0。到底是怎麼回事？
