B4X covers many platforms, technologies and interests fields. It also evolved quite quickly in the last couple of years.
The forum with almost million posts can be difficult to navigate if you are new to B4X. It is also true that there are “new” ways to do things, which are recommended now. It doesn’t mean that old solutions will not work. B4X is backward compatible.
The good news is that the new methods are usually much simpler to use. For example B4XPages, or resumable subs, really make programming simpler.
The underlying platforms (mainly iOS and Android) are moving fast and there are new requirements every year. Many of the frustrations with old solutions not working anymore, are related to Google policy where the targetSdkVersion needs to be updated yearly (android.jar / targetSdkVersion / minSdkVersion | B4X Programming Forum).
The search engine is good compared to other sites search engine. It is of course far far behind Google.
