            byte[] data=new byte[inputstream.available()];                  
            ParseFile file = new ParseFile("lmh.jpg", data);
            file.saveInBackground(new SaveCallback() {

                @Override
                public void done(ParseException e) {

                        Toast.makeText(getApplicationContext(), "ERROR: "+e, Toast.LENGTH_LONG).show();
                    else
                        Toast.makeText(getApplicationContext(), "sucess", Toast.LENGTH_LONG).show();

In your code, you are just passing empty byte array. You should first try to convert your image into byte array appropriately:

// make sure image path is correct

InputStream inputStream=assetmanager.open("lmh.jpg");
bitmap = BitmapFactory.decodeStream(inputStream);

ByteArrayOutputStream byteArrayOS= new ByteArrayOutputStream();  
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOS);
byte[] data= baos.toByteArray();

ParseFile file = new ParseFile("lmh.jpg", data);

Also, make sure your client key is copied correctly: similar error
