Question

我正在使用Xamarin.Android处理Brother标签打印机QL-710W。

我创建了一个Android绑定项目，并添加了jar文件和.so文件，如下所示。

我正在使用Visual Studio。

罐子＆gt;

BrotherPrintLibrary.jar; BuildAction：EmbeddedJar
MobilePrintLib.jar; BuildAction：ReferenceJar

NativeLibraries＆gt; armeabi＆gt;

libAndrJFPDFEMB.so; BuildAction：EmbeddedNativeLibrary
libcreatedata.so; BuildAction：EmbeddedNativeLibrary

附加 ClassTest.cs

public bool PrintFile(string fileurl, NetPrinter printer)
    {
        Task <bool> printTask = new Task<bool>(() => {
        bool success = true;
            try
            {
                Printer myPrinter = new Printer();
                PrinterInfo myPrinterInfo = new PrinterInfo();
                PrinterStatus status = new PrinterStatus();
                LabelInfo mLabelInfo = new LabelInfo();

                myPrinterInfo.PrinterModel = PrinterInfo.Model.Ql710w;
                myPrinterInfo.IpAddress = printer.IpAddress;
                myPrinterInfo.MacAddress = printer.MacAddress;
                myPrinterInfo.Port = PrinterInfo.PortEnum.Net;
                myPrinterInfo.PrintMode=PrinterInfo.PrintModeEnum.FitToPage;
                myPrinterInfo.PaperSize = PrinterInfo.PaperSizeEnum.Custom;
                myPrinterInfo.Orientation = PrinterInfo.OrientationEnum.Portrait;
                myPrinterInfo.LabelNameIndex = LabelInfo.QL700.W62.Ordinal();
                myPrinterInfo.ScaleValue = 1;

                mLabelInfo.LabelNameIndex = LabelInfo.QL700.ValueOf("W62").Ordinal();
                mLabelInfo.IsAutoCut = true;
                mLabelInfo.IsEndCut = true;

                myPrinter.SetPrinterInfo(myPrinterInfo);
                myPrinter.SetLabelInfo(mLabelInfo);

                myPrinter.StartCommunication();
                status = myPrinter.PrintFile(fileurl);
                if (status.ErrorCode != PrinterInfo.ErrorCode.ErrorNone)
                    success = false;
                myPrinter.EndCommunication();
            }catch(Exception ex)
            {
                Console.WriteLine("ERROR : {0}",ex.Message);
                success = false;
            }
            return success;
        });


        printTask.Start();

        var isSuccess = printTask.Result;

        return isSuccess;
    }

我正在从网络上成功获得打印机列表。但是当我调用上面的方法时，它会在 myPrinter.SetPrinterInfo（myPrinterInfo）; 中获得异常，因为 “无法从loader dalvik.system.PathClassLoader [DexPathList []加载createdata [zip file \“/ data / app / PocAndroidArchieve.PocAndroidArchieve-2.apk \”]，nativeLibraryDirectories = [/ data / app-lib / PocAndroidArchieve.PocAndroidArchieve-2，/ vendor / lib，/ system / lib]]]： findLibrary返回null“

如果有人有想法使用jar和依赖的.so文件，请建议我。

提前致谢。
