R RB Smissaert Well-Known Member Licensed User Longtime User Apr 8, 2018 #1 Developing a simple database app in B4A. Currently I handle application settings with File.ReadMap and File.WriteMap etc. and this seems to work well. What are the benefits of using instead the PreferenceActivity or AHPreferenceActivity libraries? RBS

I can let the user change the settings via a menu or a dedicated settings page, using File.WriteMap for persistence. I will look into KeyValueStore 2, but I like the simplicity of File.WriteMap and File.ReadMap. Similar to an .ini file and I am used to that. RBS Upvote 0

Click to expand... But I can write the Map data to a text file. I can see though that if there are a lot of settings, a database for storage has benefits, eg. multiple text replacements. Will switch to KVS2 and see how it works. RBS Upvote 0

Yes, that could be handy, saving me the conversion to and from strings. You convinced me now. Not sure yet about PreferenceActivity or AHPreferenceActivity. RBS Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Apr 8, 2018 #7 BTW, there are cases where File.WriteMap / ReadMap are more appropriate. For example in B4J apps it can be useful for configuration files as the user can modify it with a text editor. Upvote 0
