Reading array values from return method

How can I safely read both of my array values from another class method without the nullexception warning coming up.I am getting both values orreclty just worried about the "Array access x[0] may produce NPE " warning without using intents

 public Class ImageUtility{

 public static String[] savePicture(Context context, Bitmap bitmap) {

  ......

   String[] arr = new String[2];
        arr[0] = img_name;
        arr[1] = img_path;

        return arr;
   }



public Class Others{

 public void Test(){
 String[] x = ImageUtility.savePicture(getActivity(), bitmap);
 value_one= x[0]; //nullexception warning is here
 value_two= x[1];

  }

Try the following code

 public void Test(){
   try{
     String[] x = ImageUtility.savePicture(getActivity(), bitmap);
     if(x != null && x.Length >= 1){
       value_one= x[0]; 
       value_two= x[1];
     }
   }catch(NullPointerException e){
     //print log
   }
 }
