Android Photo Camera Upload with Retrofit - ASP.NET MVC Endpoint -

want able on fly post image back-end android app. doing wrong here? keep receiving internal server error, know endpoint , working (able call other clients)

i have asp.net mvc endpoint setup this:

    [httppost]     public jsonresult postimage(int id, string accesstoken, httppostedfilebase img) 

in android code, using retrofit setup this:

@multipart @post("/endpoint/postimage") void postimage(         @part("id") int id,         @part("accesstoken") typedstring accesstoken,         @part("img") typedbytearray img,         callback<boolean> callback); 

i have image handling code this:

bytearrayoutputstream bos = new bytearrayoutputstream(); bitmap.compress(bitmap.compressformat.png, 0, bos); byte[] bitmapdata = bos.tobytearray();  //  convert typed typedbytearray typedbytearray = new typedbytearray("application/octet-stream", bytes); typedstring str = new typedstring("mystring");  restadapter adapter = new restadapter.builder()         .setendpoint("https://myendpoint.net").build();  apiservice apiservice = adapter.create(apiservice.class); apiservice.postimage(1492, str, typedbytearray, new callback<boolean>() {      @override     public void success(boolean success, response response) {          boolean test = success;     }      @override     public void failure(retrofiterror error) {          //log.e("tappedin", error.getmessage());     } }); 

fyi i've resolved this!

here final code:

protected void onactivityresult(int requestcode, int resultcode, intent data) {    if (requestcode == 1 && resultcode == result_ok) {    bundle extras = data.getextras();   bitmap bitmap = (bitmap) extras.get("data");    bytearrayoutputstream out = new bytearrayoutputstream();   bitmap.compress(bitmap.compressformat.jpeg, 65, out);   byte[] bytes = out.tobytearray();    restadapter adapter = new restadapter.builder()   .setendpoint("https://myendpoint.com").build();    apiservice apiservice = adapter.create(apiservice.class);    typedbytearray typedbytearray = new typedbytearray("image/*", bytes) {     @override     public string filename() {     return "img.jpg";     }   };  typedstring myvar = new typedstring("abc");  apiservice.postvenuemenu(venueid, myvar, typedbytearray, new callback<successdto>() {                  @override                 public void success(successdto success, response response) {                  }                  @override                 public void failure(retrofiterror error) {                  }             });         }     }
