Android Question BrotherSDK2B4A problem

[mc73]

I really don't know what's going on, though I suspect I did something wrong with the placement of 'so' files.

I used 'simpleLibraryCompiler (1.01)' and then I added just a void to perform printing. Lib is loaded, but upon run I get

java.lang.UnsatisfiedLinkError: Couldn't load createdata from loader dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/b4a.example-2.apk"],nativeLibraryDirectories=[/data/app-lib/b4a.example-2, /vendor/lib, /system/lib]]]: findLibrary returned null

   at com.brother.ptouch.sdk.Communication.createPrinterModel(Communication.java:275)
   at com.brother.ptouch.sdk.ComNet$CommunicationThread.run(ComNet.java:473)

Seems that a lib is missing, though I've added the brotherLib to both the additional folder of b4a and of my workspace. Yet, I'm not sure about the 'so' files.

The code of void goes like this, just in case anyone sees something wrong:

package biz.logismic;
import com.brother.ptouch.sdk.*;

import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.*;

@Version(3.0f)
@ShortName("BrotherPrintSDK")
@DependsOn(values={"BrotherPrintLibrary"})
public class brotherSDK {
   
   public void print(String filePath,String printerIP,String macAddress){
     
     Printer myPrinter = new Printer();
     PrinterInfo myPrinterInfo = new PrinterInfo();
     PrinterStatus printResult = new PrinterStatus();
     LabelInfo mLabelInfo=new LabelInfo();
     try{
     
       myPrinterInfo = myPrinter.getPrinterInfo();
       myPrinterInfo.printerModel=PrinterInfo.Model.QL_710W;
       myPrinterInfo.printMode=PrinterInfo.PrintMode.FIT_TO_PAGE;
       myPrinterInfo.port=PrinterInfo.Port.NET;
       myPrinterInfo.paperSize = PrinterInfo.PaperSize.CUSTOM;
       myPrinterInfo.orientation = PrinterInfo.Orientation.PORTRAIT;
       myPrinterInfo.numberOfCopies = 1;
       myPrinterInfo.ipAddress=printerIP;
       myPrinterInfo.macAddress=macAddress;
     
       mLabelInfo.labelNameIndex=LabelInfo.QL700.valueOf("W62").ordinal();
       mLabelInfo.isAutoCut = true;
       mLabelInfo.isEndCut =true;
       
       myPrinter.setPrinterInfo(myPrinterInfo);
       myPrinter.setLabelInfo(mLabelInfo);
       printResult=myPrinter.printFile(filePath);
     } catch(Exception e){   
     }}}

I'm almost sure, there is a simple solution, but can't figure it out

You should move the so file under the location specified in a post above:

The problem was with the location of 'so' file. I had it under 'additional', but I had to add the 'lib' subdirectory under 'additional' first

I really don't know of other cause. However, I notice you used the 720 model. I used this model in the past, and there was no need for an SDK. I simply used to send ESC POS commands directly to the printer.

i don't know how to do that and i spend so much time to fix this lib
is this where the so files need to be ?
SimpleLibraryCompiler\BrotherSDK\libs\additional\lib

' r.Target = r.RunMethod("permitAll")
' r.Target = r.RunMethod("build")
' r.RunStaticMethod("android.os.StrictMode", "setThreadPolicy", _
' Array As Object(r.Target), Array As String("android.os.StrictMode$ThreadPolicy"))
'End If
