How do I store this 2 Dimensional array in strings.xml?
private String[][] children = { { "Arnold", "Barry", "Chuck", "David" }, { "Ace", "Bandit", "Cha-Cha", "Deuce" }, { "Fluffy", "Snuggles" }, { "Goldy", "Bubbles" } }; Your usage case would help answer the question, because depending on your situation, my suggestion would be to put the individual Strings in strings.xml and then use an int[][] inside your class pointing to the string resources:
private final int[][] children = { { R.string.arnold, R.string.barry, R.string.chuck, R.string.david }, { R.string.ace, R.string.bandit /*etc*/ } // etc // ... }; I know that doesn't directly answer your question as to how to do that in XML, but unless you provide a usage case that makes it clear that it's necessary to do that, there's no reason to do anything harder than what I've described.
