no I am using LibraryCompiler 1:03 and -b4aignore "org.com.android.com.OCRReader.com.hoho" and fair?
and the error is

if you want to compile the java code then -b4aignore should only have com as its entry - provided that you have browsed to the correct folder to try and compile from and that you have created a libs folder on the same folder level as the src folder that contains the JAR's from the link in post #41 except for:

OCRReaderComplete.jar
OCRReaderComplete.xml

The above jar and xml will be created and added to you additional library folder when you compile the java code into a library.

But if you only want to run the last B4A project that I have posted then you need all the JAR's and XML's that you can download from the link in post #41 to be in your additional library folder.

thanks for your time, and now everything is ok, I can modify the library? I am creating a program for license plate recognition.

See post #17 - it should do it.

Hello Johan, and you can have the lib matrix. AndroidVisionOCR ?, I do not know java very well and I would like to understand the operation.
Greetings

Not sure I understand what you mean with lib matrix Roberto. Please explain

 

[roberto64]

the project in java.

 

[roberto64]

hi Johan, you can make a native library in B4A using #If JAVA "Java code" #End If entering classes of OCRReaderComplete library.

Hi Johan, I would ask a cortesiaper the TheJavaCode source code Library Updated Version 1.1 AndroidVisionOCR, I do not know a lot about java.

HI! I am trying the example but I got the following compiler error:

Generating R file. Error

Can someone help? What I am missing?
PS
Libraries are there
Resource and OCRres
In the project folder

Try to use a newer version of android.jar under Tools - Configure Paths.

Roberto, do you want a copy of the Java code? Is that what you are asking?

Roberto, download the Java code and the JARS that you need from this link (folders src and libs):
https://www.dropbox.com/s/4sg0ifcz5mxgofb/JavaCode_and_libs.zip?dl=0

If you want to compile the code then you need to create a folder called libs on the same folder level as the src folder and copy the JARS into the libs folder. You will also need to copy the JARS to your B4A additional library folder to run the B4A project.

Thus, folder structure to compile should be:

your_folder_name

src

androidvisionocrwrapper

androidvisionocrWrapper.java​

com

all the subfolders and java files......​

libs

all the jar files downloaded from the link above​

thanks for your time, I would like to figure out how to build a library B4A, I'm trying but in vain to figure out how to write it in eclipse that I have never used, or there is another editor to scruvere code, I do not understand when you import anywheresoftware .. . if there is a manual to understand its functions, I thank you anyway for your time that you gave me.

hi johan, I compiled with LibraryCompiler your AndroidVisionOCR package ristituisce me this error

Roberto, I cannot help you with Eclipse. I do all my editing with Notepad ++ and then compile it with @Erel's Simple Library Compiler. Much easier than trying to learn what is happening in Eclipse.

Roberto, I think it will be easier to start with something simpler. There is unfortunately no manual available for this. You have to search the forum and post questions in the Libraries Developer Forum. There are also a number of good examples by @DonManfred that should assist.

But to get back to your original question- you can scan license plates with the library. I have tested it and it works very well.

Do you perhaps have my library and your newly complied library both enabled at the same time in your B4A project?

 

[roberto64]

hi johan, thank you, I solved by inserting "-b4aingnore" com.

Hi
I have installed all the jar's etc but get an error when I try to compile.

B4A version: 6.80
Parsing code. (0.00s)
Compiling code. (0.15s)
Compiling layouts code. (0.01s)
Organizing libraries. (0.00s)
Generating R file. Error
invalid resource directory name: C:\Program Files (x86)\Anywhere Software\Basic4android\Programs\b4aAndroidVisionOCR\Objects\bin\extra\res6\res/drawable-anydpi-v21

The path is correct and there is a folder drawable-anydpi-v21 but I still get the error.

Any idea what might be wrong.
