Probably no.
It may be possible if any library expose a getVersion method which give the version back. But i did not saw any lib so far which does this.
All my libs does not expose such a method (getter) too.

Thanks DonManfred
But how B4A IDE does this ? Appears library version in Libraries Manager. It should not be exposed programmatically ?

Nice. Got it. But an xml file is not visible to my application that uses a determines referenced library. Right ?

This gave me an idea. Include own xml or txt with the version in the files directory of my application. Single drawback is that when you change the library version will have to change this file . Should work.

Call this inline Java using the usual method:
Beware that there's no Exception catching, here. If the Object you pass as a parameter doesn't have a @Version annotation, it will blow up your app.
B4X:
#If JAVA
public static float GetVersion(Object o)
{
return o.getClass().getAnnotation(anywheresoftware.b4a.BA.Version.class).value();
}
#End IfBeware that there's no Exception catching, here. If the Object you pass as a parameter doesn't have a @Version annotation, it will blow up your app.

Thanks Roycefer. What parameter to (Object o). Where I got it ? (Object o) . I need put this in params:
If nativeMe.IsInitialized=False Then nativeMe.InitializeContext
Dim SQLCipherVersion As Float=nativeMe.RunMethod("GetVersion", Params() As Object) '<=== What's params library name here ?
I find this in xml of the library ?

Whatever Object you want, so long as it has an @Version annotation in its Java code. This will usually be the "central" object of a library. If a library only has one class, then create an instance of that class and use that as the parameter.
I haven't used the SQLCipher library but looking at its documentation, there is only one class and it is the SQLCipher class.
Untested, beware.

Dim sc as SQLCipher
sc.Initialize(blah, blah, blah, blah, ....)
Log("version is: " & nativeMe.RunMethod("GetVersion", Array(sc)))Untested, beware.

I got this error in Log line of my code:
My code:
But the SQLCipher object was initialized.
My code:
B4X:
...
Dim sc As SQLCipher
sc.Initialize(File.DirInternal,"xxx.db",True,"dkjfakldfj", "")
Log("version is: " & nativeMe.RunMethod("GetVersion", Array(sc)))
...
#If JAVA
public static float GetVersion(Object o)
{
return o.getClass().getAnnotation(anywheresoftware.b4a.BA.Version.class).value();
}
#End IFBut the SQLCipher object was initialized.

You are right. when I changed the code forgot to do this. Works perfectly !!! Great !!! You are master because in google I don't found this.
now my correct code:
