Android Question How to create library?

[Theera]

I tried to create ThaiMoney library by slc tools,but it created only jar file. It can't create xml file ,too. How do I do?

Libraries are stored in jar files. A jar file is basically a ZIP file.
If you've created the library correctly, you just need to copy the jar file into the appropriate 'Additional Libraries' folder, probably the /B4A sub folder.
Provided you've configured the Additional Folders in the IDE, your library should appear in the Libraries pane of the IDE.

No, the XML file is needed for B4A to identify it as a library.

Have you downloaded this? It includes a sample library that should compile to a jar and an xml file and place them in your additional libraries folder. If that works you can model your library on that.

[Tool] Simple Library Compiler - Build libraries without Eclipse

The purpose of Simple Library Compiler (SLC) is to make it easier to build libraries. SLC is responsible for taking the Java source code files and generating the Jar and XML files. As I see it, it can be useful in two cases: - Creating wrappers for 3rd party SDKs. - Modifying and extending...

Note that for libraries you should use Java 8 to compile (SLC uses the Java presently selected in B4A IDE) as BADoclet can produce corrupted xml files on later Javas.

After I changed Java8,I can make both of them. When I run my library,it has error. I try change encoding UTF8 and UTF8 BOM,but I can't solve it.

I've tried compiling the source above and get the same problem. If you delete the comment in getText I get a slightly different error

error: unmappable character for encoding Cp1252

The jar has compiled properly but it looks to me like BADoclet, which produces the xml file, is trying to map the UTF8 characters in ThaiMoney.java to an 8 bit code page and is trying to guess which one and then failing to map the Thai characters. Erel needs to look at this.

For the time being try saving the compiled jar in the additional libraries. Then edit the source to remove the Thai comment in getText and empty the three arrays of Thai characters then compile again. This produces the xml, attached below, and a new jar in additional libraries. Replace the new jar with the original compiled jar and hopefully it should work.

I have test it already,but I didn't work for me. However,I will redo all new again. Thank you,Agraham.
