   \"status\":\"succes         


        

Answer 1

public int image_width;     // Expected integer value while parsing 

public int image_height;   // Expected integer value while parsing

as you can see below you are having string fields . Initialize below vale to 0

"image_width":0,
"image_height":0

Answer 2

Change the type of image_width and image_height to String in MyData Class

public String image_width;

public String image_height;

As int will not be able to store "" this string, and at the time of using it you can parse it into int.
