color-array from color.xml returns null for all items.

I have made an color-array containing 12 different colors in color.xml. But in my attempt to extract the colors and use them in the code I get null for all values in the array. I also tried to use the TypedArray solution with no difference. So what is wrong?

    public void testColor(){

    Resources resources = App.getAppContext().getResources();
    String colors[] = resources.getStringArray(R.array.backgroundcolors);

    //prints null
    Log.d("TAG", " " + colors[3]);

    //prints 12x null 
    for(String x : colors){
        Log.d("TAG", " " + x);

    }
}


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    testColor();
}

color.xml

<array name="backgroundcolors">
    <item>#000000</item>
    <item>#373737</item>
    <item>#ffffff</item>
    <item>#e6e6e6</item>
    <item>#EAE1D8</item>
    <item>#fd79a1</item>
    <item>#ff0f68</item>
    <item>#E849A1</item>
    <item>#F7E84E</item>
    <item>#FFB732</item>
    <item>#48B1E3</item>
    <item>#5dd95d</item>
</array>

Solution 1

You should get the array as int array like this

int colors[] = resources.getIntArray(R.array.backgroundcolors);

Solution 2

If you want to read it as a String array then

change

<array name="backgroundcolors">

to

<string-array name="backgroundcolors">

You can use 

 Color.parseColor(colors[i]))


Color.parseColor("#636161")

if you want to use getStringArray, you should be useing 

<string-array

as root tag instead of <array and content should be placed in strings.xml. Colors are int. You can use getIntArray to retrive an array of int from the res
