ArrayList<String> newArray = new ArrayList<String>();
newArray = urlList.getUrl();
for( int i = 0 ; i < newArray.size();i++)
{
    System.out.println(newArray.get(i));
}

newArray.toArray(mStrings );// is this correct 
mStrings = newArray.toArray();//  or this to convert ArrayList ot String array here

for( int i = 0 ; i < mStrings.length;i++)
{
    System.out.println(mStrings[i]);
}

EDITAR cuando intento lo siguiente, obtengo una excepción de puntero nulo:

try
{
    newArray.toArray(mStrings );
    for(int i = 0 ; i < mStrings.length; i++)
    {
        System.out.println(mStrings[i]);
    }
} catch( NullPointerException e )
{
    System.out.println(e);
}
