And here my error:

I don't know why. Doing this on different files and same way (getting resources from an XML) it works clean. I spent a lot searching on Google and this web without results. I hope you can solve it! Thanks for any help!

  • Show the code. Here you try and allocate an array of Object with more than 2^31 - 1 elements. Commented Apr 15, 2015 at 11:11
  • use String[]=resources.getStringArray(R.array.plants); and then create arraylist using this string array Commented Apr 15, 2015 at 11:21

R.array.almazaras is an integer constant (in your example, it's 2131099649).

You should be using the constant to fetch the resource first, then put them in your ArrayList.

First get String array by,

Resources res = getResources();
String[] almazarasItems  = res.getStringArray(R.array.almazaras);

And add the String array to ArrayList by,

List<String[]> arrayList = new ArrayList<String[]>();
arrayList.add(almazarasItems);

@Kayaman is right. You're referring to the constant reference to the array.

Try this, it should do the trick. 

    String arr[] = getResources().getStringArray(R.array.almazaras);
    ArrayList<String> almazaras= (ArrayList)Arrays.asList(arr);

You can't call almazaras=new ArrayList<>(R.array.almazaras); to initialize your List. In Android, R.array.almazaras is the address of your array resources, like integer-array, string-array. You can find its value which is in Hex format in gen/pkg-name/R. Maybe you can call almazaras=new ArrayList<>(); or almazaras=new ArrayList<>(a-int-value);.

You are using an ID to initialize an Arraylist. But the constructor oft ArrayList interpreters the Parameter as the length that the ArrayList should be at initialition.

So you are creating an Arraylist with the initial length of 2131099649 which is too much.

You can optain your array with context.getResources().getStringArray(R.array.almazaras);
