I’m working on a little Android project in java, I’m using the webapi of spotify to get me so data to play around with.

First thing I notice when visiting: https://developer.spotify.com/technologies/web-api/ is that a developer can choose to use xml or json.

What i would like to do is ‘cache’ my data so i can do the following:

  • read one value from the file, or construct an object based on different values
  • add the object created above to the lisviewadapter
  • update the listview with the updated adapter
  • iterate over previous steps until parsing of file is complete

I want to be as quick as possible for my users so that the ui gets updated while parsing and loading the data. For this I sketched 2 use-cases.

  • add items to the listview until done
  • show a X amount of items and show a load more button

What file type is more ideal to use for my problem? xml parsing or json parsing?

How can i do this parsing? which tools meet my requirements?

Which use-case seems better to use?

any tips if you have done something like this in the past?

any guidance is appreciated

    I don’t make any distinction between XML or JSON. To cache data you have two options. Either write the data to a file (will require reparsing of the file to extract the data (unless you create a new file of, for example, CSV data)) or write the required data to a database after parsing. As for updating ListView, that would be up to you based on the number of entries you have.

    Android has both XML and JSON parsers built-in. You don’t need GSON.
