How can I add an image file into json object

Question

I want to add an image file into json object   Is it possible to add image file into json object   I tried below code but its not working   Because i want to send that json object to the server then server will read my image file and store into that database   JSONObject test   new JSONObject    test put  photo  new File    Here i set image uri      So when I print this json object it only show me the image path where the image stored  I want file for sending it to server

You re only adding the File object to the JSON object  The File object only contains meta information about the file  Path  name and so on    You must load the image and read the bytes from it  Then put these bytes into the JSON object

You will need to read the bytes from that File into a byte   and put that object into your JSONObject   You should also have a look at the following posts     ByteArray in JSON Binary Data in JSON String  Something better than Base64 BSON library for java   Hope this helps
