Libs created with 2.5 not compatible with previous versions?

[margret]

The test libs I have created work fine in the 2.5 beta but will not work with the previous 2.22 version. Are the libs created with 2.5 only forward compatible?

Up until v2.50 libraries were only made of classes. A Java library cannot expose an activity or service to B4A (it can include an internal one).

Libraries that will only include classes should work with previous versions.

This test lib works fine in 2.5 and only includes classes but produces the error below in 2.22:

Compiling code. 0.01

You are correct. Libraries will only work with v2.50 or higher.
