Android Question File.WriteList -> convert to string -> why?

[KMatle]

I've never asked for the reason

As known File.WriteList will convert the values to strings. To me this makes no sense as a List can hold any data type.

Is there a reason for that behaviour? (Maybe because the written file is a textfile?)

You should use Randomaccessfile and here Writeb4xobject to write a List (with it´s items).

I wasn't precise enough The question is: Why is there a method (File.WriteList) when this method (does not work properly). Properly = Writing a List as it is.

Writing a List as it is.

I guess in B4A 1 a list just could contains Strings. I dont know. I cant answer this WHY

If you think this is an error than you can create a thread in the bug and wishlist forum.

File.ReadList reads a text file and returns a list with its lines.
File.WriteList writes a list to a text file where each item is written to a separate line.

The answer to your question is that this is how these methods were designed (and documented).
This behavior will never change.

If you want to serialize a list then use B4XSerializator or RAF.WriteB4XObject. The result will be different. You will get a binary file.
