Best method for declaring / populating arrays

    Hi,

    In terms of efficiency, is it better to use arrays programmatically or through calls to xml files.

    I'd prefer to use xmls for organisational reasons, but is there much of a performance hit.

    Populating via xml will have an overhead and be a little worse in terms of performance than programmatic population, but not by much. Depending on the problem and the size of the data set, I would say that xml would be the better choice.


    Actually, are you referring to your own xml files or the built-in android xml arrays?

    If you use android's built-in arrays.xml stuff, there won't be any overhead at runtime. android interperates the xml at compile time and generates the array for you.

    Thanks.

    I usually create an 'arrays.xml' file and put all arrays in there.
    Is this considered a built-in xml?

    Eclipse creates strings.xml and values.xml by default, so I'm not sure what the built-in ones you refer to are!

    yes, I consider arrays.xml a built in xml as it is interperated at comile time by the ADT.
