convert a string got from Jsonobject to Byte[];

Question

I am transmitting a PDF in Bytearray from WEB API,

I am getting the response as follows

 {"document":"JVBERi0xLjMNCiXi48\/TDQoNCjEgMCBvYmoNCjw8DQovVHlwZSAvQ2F0YWxvZw0KL091dGxpbmVzIDIgMCBSDQovUGFnZXMgMyAwIFINCj4+DQplbmRvYmoNCg0KMiAwIG9iag0KPDwNCi9UeXBlIC9PdXRsaW5lcw0KL0NvdW50IDANCj4+DQplbmRvYmoNCg0KMyAwIG9iag0KPDwNCi9UeXBlIC"}

I want to convert that string to Byte array[] for rendering the PDF;

Please Help me with problem;

Try this

String json = "{\"document\":\"JVBERi0xLjMNCiXi48\/TDQoNCjEgMCBvYmoNCjw8DQovVHlwZSAvQ2F0YWxvZw0KL091dGxpbmVzIDIgMCBSDQovUGFnZXMgMyAwIFINCj4+DQplbmRvYmoNCg0KMiAwIG9iag0KPDwNCi9UeXBlIC9PdXRsaW5lcw0KL0NvdW50IDANCj4+DQplbmRvYmoNCg0KMyAwIG9iag0KPDwNCi9UeXBlIC\"}";

JSONObject json_object = new JSONObject(json);

byte[] b = json_object.getString("document").getBytes();
//or
byte[] b = json_object.getString("document").getBytes(Charset.forName("UTF-8"));

As simple as :

byte[] byte = yourstring.getBytes();
byte[] byte = yourstring.getBytes(Charset.forName("UTF-8"));

Use getBytes() method in string

I was able to get the Bytearray from JSON using

  pdfbytes =   Base64.decode(response.getString("document"), Base64.DEFAULT) ;
