When compiling a b4a project i get the error

It is an similar problem like i have with my pdfRenderer2-Library

To to the fact that this library is a short one i think i should start to fix this problem.

I´m using SLC 1.01 and B4A 4.0

 

but i have no two jar referenced. Only one

 

java.lang.IllegalArgumentException: already added: Lcom/readystatesoftware/viewbadger/BadgeView;

WHEN I CREAT JAR FILE BY "LibraryCompiler.EXE",IF I USE TWO JAR IN MY B4A PROJECT,IT'S ERR,IF ONLY USE ONE JAR,IT'S GOOD,WHY?

 

NOT THIS QUESITON,I OPEN THE FOLDER ,AND DELETE MORE FILES IN \src\bin\classes\***
BECAUSE I COPY THE SAMPLE JAR PREJECT ,AND IT'S HAVE THE OLD CLASS . SO IT'S OK!

 

WHEN I write jar libraries,i can't find a small tool,i hope you can design a ide tool like "b4a",so i can write java code in your soft.
i only need the code like "
import java.io.File;
import android.content.Context;
import android.os.Environment;


public static void cleanDatabaseByName(Context context, String dbName) {
context.deleteDatabase(dbName);
}

if i write code like "context.", it will show more method let me select ,like context.deleteDatabase.
more times ,basic code like java ,only {} () not same ,and java have ";" in every line.

if a easy tool can write basic code same like java,it's very good?
it's b4j?
i want to put java code and quick use,if i learn b4j,it's need money to buy b4j,and it's hard,
i only want a easy ide to write java code,for create jar libraries ,to b4a use.
