I'm Working on Brother Label Printer QL-710W using Xamarin.Android.
I have created a Android bindings project and Added jar files and .so files as shown below.
I'm using Visual Studio.
Jars >
- BrotherPrintLibrary.jar; BuildAction: EmbeddedJar
- MobilePrintLib.jar; BuildAction: ReferenceJar
NativeLibraries > armeabi >
- libAndrJFPDFEMB.so; BuildAction: EmbeddedNativeLibrary
- libcreatedata.so; BuildAction: EmbeddedNativeLibrary
Additions 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;
}
I'm getting printers list successfully from network. But when I'm calling above method it is getting exception at myPrinter.SetPrinterInfo(myPrinterInfo); as "Couldn't load createdata from loader dalvik.system.PathClassLoader[DexPathList[[zip file \"/data/app/PocAndroidArchieve.PocAndroidArchieve-2.apk\"],nativeLibraryDirectories=[/data/app-lib/PocAndroidArchieve.PocAndroidArchieve-2, /vendor/lib, /system/lib]]]: findLibrary returned null"
Please suggest me if any one has idea to work with jar's and dependent .so files.
Thanks in advance.
