is there a public database with a list of librarys, her methods and events?
in mssql or sqllite format, or csv / excel / xml?
the base of this page here starting at Libraries https://www.b4x.com/android/documentation.html
You should use ObjectBrowser
There is no official Database externally though there is an XLS file somewhere in the forum with a List of all Library made by one of the Members.
