C++ Builder：包含JAR文件

我正在使用C++ Builder 10.1 Berlin Enterprise開發移動應用程序。應用程序的目標是掃描條形碼，我使用帶有條碼掃描器的Android PDA。與掃描器相關的功能包含在JAR文件中。C++ Builder：包含JAR文件

如何在我的項目中使用這些功能？

編輯

我已經將JAR添加到我的項目，但我不知道我有什麼，包括使用掃描功能。

EDIT 2

我創建了一個橋文件，Java2OP。根據Embarcadero文檔，我必須手動將它翻譯爲C++，但我不瞭解Delphi。這裏是代碼：

unit Android.JNI.ATLib; 

interface 

uses 
    Androidapi.JNIBridge, 
    Androidapi.JNI.JavaTypes; 

type 
// ===== Forward declarations ===== 

    JATLib = interface;//com.atid.lib.ATLib 

// ===== Interface declarations ===== 

    JATLibClass = interface(JObjectClass) 
    ['{E264906A-B076-4960-9EAE-17DF2D2AEE74}'] 
    {class} function _GetINTERNAL_PATH: JString; 
    {class} procedure _SetINTERNAL_PATH(Value: JString); 
    {class} property INTERNAL_PATH: JString read _GetINTERNAL_PATH write _SetINTERNAL_PATH; 
    end; 

    [JavaSignature('com/atid/lib/ATLib')] 
    JATLib = interface(JObject) 
    ['{EFCFE579-FB94-432F-8DBB-851521F1EED7}'] 
    end; 
    TJATLib = class(TJavaGenericImport<JATLibClass, JATLib>) end; 

implementation 

procedure RegisterTypes; 
begin 
    TRegTypes.RegisterType('Android.JNI.ATLib.JATLib', TypeInfo(Android.JNI.ATLib.JATLib)); 
end; 

initialization 
    RegisterTypes; 
end.

你可以給我一些建議，將其轉換爲C++？

我也嘗試包括PAS文件，但是當我整理的項目，我有這樣的錯誤：

Compiler for "Delphi.Personality" and the platform "Android" is missing or unavailable.

編輯3

我成功了我的橋樑文件++轉換到C感謝這個post。我試圖使用該功能在我的應用程序是這樣的：

TJATScanLib* scan = new TJATScanLib(); 
_di_JATScanLib scanner = scan->JavaClass->init();

編譯過程中，但在鏈接步驟沒有任何問題，我有這些錯誤：

您可以簡單地使用項目經理來做到這一點。

在項目管理器中，擴展項目的目標平臺節點。
在Target Platforms節點中，擴展Android節點。右鍵單擊庫節點並選擇添加。
在打開的對話框中，選擇要添加到Android應用程序的.jar文件，然後選擇打開。

我已經這樣做了，但我不知道要使用哪些文件來使用JAR文件的功能。 – Dylan

您需要將JAR文件本身添加到Android節點中。之後，您必須將正確的導入添加到代碼中。 –

@JeanVitor「正確導入代碼」就是缺少的東西。僅僅添加JAR文件本身是不夠的，您還需要使用JAR文件內容的代碼。你*可以*手動編寫該代碼，但是這樣做乏味且容易出錯。 Embarcadero擁有一個Java2OP工具，可爲您生成該代碼。 –

本主題涵蓋英巴卡迪諾的文檔中：

Using a Custom Set of Java Libraries In Your RAD Studio Android Apps

RAD Studio allows you to use your own or third-party Java libraries in RAD Studio applications.

To use a custom set of libraries in your RAD Studio Android applications:

Ensure that your Java libraries meet the RAD Studio requirements for Java libraries .

Create a native bridge file that your Delphi or C++ applications can use to access the APIs of your Java libraries.

Add your Java libraries to your application .

什麼你缺少你的項目是第2步。您可以使用Embarcadero的Java2OP工具來生成該橋文件。

我知道我錯過了第2步，但是當我想下載Java2OP時，它說我沒有好的版本。我需要一個XE，我有柏林10.1 – Dylan

我不明白你在說什麼。 Java2OP是柏林的一部分，你不需要XE版本。只需登錄您的EDN帳戶並下載Java2OP for Berlin。您應該事先已經註冊了柏林牌照。 –

對不起！我以爲我已經註冊了我的柏林牌照，但我仍在使用試用版。我下載了Java2OP，並且即將創建一個橋文件。有消息通知你。 – Dylan
