String.format or getString

In order to format a string, I always use String.format(getString(R.string.something),arg1)

However I saw on the documentation getString(string, args) could do the same.

Therefore, I wonder why everyone use String.format if getString can do the same

Thank you

You are mistaken, there is no method Resources.getString(string, args...) or Context.getString(string, args...). There is Resources.getString(int, args...) that takes an int and objects.

When formatting a string you would use String.format(string, args...). But in Android your string resources are probably in the res folder so you have a convinience method for getting the string from the resources and formatting it with String.format. It does the same thing as you did (taken from Android source):

@NonNull
public String getString(@StringRes int id, Object... formatArgs) throws NotFoundException {
    final String raw = getString(id);
    return String.format(mResourcesImpl.getConfiguration().getLocales().get(0), raw,
            formatArgs);
}

You would use it like:

getString(R.string.something, arg1)

and save yourself some typing.
