You don't need to store two values in an array for this.

List the string constants as shown below under /res/values/ in the strings.xml file:

<string name="false">Whatever you want to be false</string>
<string name="true">Whatever you want to be true</string>

Implement the following code as shown below in your java file:

public class CrystalBall
{

    public String getAnAnswer( )
    {

        String[ ] facts = new String[ 2 ];

        facts[ 0 ] = new String( getString( R.string.false ).toString( ) );
        facts[ 1 ] = new String( getString( R.string.true ).toString( ) );

        boolean isFact = false;
        int randomNumber = ( int )( Math.random( ) *101 );

        if( ( randomNumber <= 50 ) && ( randomNumber >= 0 ) )
        {

            isFact = true;

        }

        if( isFact )
        {

            return facts[ 1 ];

        }
        else
        {

            return facts[ 0 ];

        }

    }

}
