Hi,
I am trying to generate a bar code and save it in a file (jpg, png, ..) from WinDev Mobile 22. For this I am using a very simple procedure in java that (importing the library barbecue-1.5-beta1.jar), I compiles correctly when generating the apk.
The problem that I find is that when calling this procedure from a button on a form, when compiling, I get the following error:
: compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.). C: \ My Mobile Projects \ BerCodeGenerator \ Android \ Generation \ src \ com \ mycompany \ bercodegenerator \ wdgen \ GWDFWIN_NoName1.java: 143: error: unreported exception Exception; must be caught or declared to be thrown vWD_sResult.setValeur (GWDCPCOL_GlobalProcedures.TestBarcode ());
I know little about Java programming, so if someone can help me identify the problem, I would appreciate it.
The Java code is the following:
import java.io.File; import net.sourceforge.barbecue.Barcode; import net.sourceforge.barbecue.BarcodeFactory; import net.sourceforge.barbecue.BarcodeImageHandler;
public static String TestBarcode() throws Exception {
try { Barcode barcode = BarcodeFactory.createCode39("70215000340", true);//BarcodeFactory.createCode39(text, checkSum);
File imgFile = new File("C:\testsize.png");
//Write the bar code to PNG file BarcodeImageHandler.savePNG(barcode, imgFile); return "1";
} catch (Exception e) { e.printStackTrace(); return "0"; } } |

Thanks Fabrice,
I have managed, with what you propose, to be able to compile and execute the application in the disositive, but when executing the java procedure, it shows me the following error: Failed Resolution Of: Lnet / sourceforge / barbecue / Barcode and I made the application, but this is another problem to solve!
