Android Question Call the external .jar file

[ericwcc]

Hi!

I planned to develop a B4A application program which will involve a 3rd party API and it was wrapped in a .jar file. How can I call the functions in that .jar file? Is it need to convert the .jar into the B4A library first? If yes, how can I convert the .jar into a B4A library? Thanks.

s it need to convert the .jar into the B4A library first?

yes

If yes, how can I convert the .jar into a B4A library?

you need to write a wrapper for this in java. You need java knowledge. There is no automatic conversion.

Thanks! In case I only have the .jar file from the 3rd party, can I create the .xml file to produce the B4A library?

Otherwise, I need to create a dummy Java program to accept the calling from B4A program and call the related function in 3rd party .jar. Is it correct?

No. You need to create a wrapper-library in java which can be used in b4a.
