Android Question how to create activity in libraries to use in the app

[Roberto P.]

I created a small library to manage related activity in some form. I would like to make small functional modules in libraries for use in various app.


I call these forms in an app (with startActivity) but the system generates this error:

Mistake or something you can not do this?

The error Sounds like an B4J issue = WrongForum?

 

[Roberto P.]

I confirm that it is a problem of B4A.

 

[DonManfred]

and you are trying to start an b4j app?

...Classnotfoundexception.... b4j.push....

Have you created an Activity entry in your manifest for the Activity that's in your library?
If not then that might explain the (Activity?) class not being found.

The manifest syntax is:

AddApplicationText(<activity android:name="my.library.package.name.myclassname"/>)

and you are trying to start an b4j app?

DonManfred you're right, there are other errors of another test I'm doing. I did another test and this is the result.

You need to add frmmain.bal to your project.

Hi Erel,
this makes you lose the advantage of creating a standalone library.

There is another way to create basic modules (items, customers, etc.) to use eg create complete functional modules to be reused in different parts?
thanks

Asset files must be added to the project. It is not possible to merge them in the jar file.
