I'm in trouble with parsing Json buffer data to image.

Here is my Node.js code and data. I send it to my app using res.send(docs).

query.find({}, function(err, docs){
    if(!err){
        console.log(docs);
        res.send(docs);
    }
});

{ _id: 555ee1f5be40576c28c3e228,
    email: 'hh@hh.h',
    pw: 'aa',
    name: 'jimy',
    phone: '22222222222',
    __v: 0,
    img: 
     { _bsontype: 'Binary',
       sub_type: 0,
       position: 4146282,
       buffer: <Buffer ff d8 ff e1 96 f8 45 78 69 66 00 00 4d 4d 00 2a 00 00...}
}

and here is my android app code. I used AsyncHttpClient.

HttpClient.post("getMember/", param, new AsyncHttpResponseHandler() {
    @Override
    public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
        JSONArray jarr;
        JSONObject obj;
        try {
            jarr = new JSONArray(new String(responseBody));
            obj = jarr.getJSONObject(0);

            email_edt.setText(obj.get("email").toString());
            pw_edt.setText(obj.get("pw").toString());
            name_edt.setText(obj.get("name").toString());
            phone_edt.setText(obj.get("phone").toString());
        }
   }
}

this code works well at document without img field. but when it get response including img, It takes long time, and fired "OutOfMemory" Error. I don't use obj.get("img"), just get responseBody and parsing it to JSONObject. document's size is about 4BM, It is not too large, but in my android studio, log like below so many times.

  • it is similar issue, but there is no answer, and I believe someone trying to get image at android from mongoDB can answer my question. Please Help me all of you ::) – YoungHoon Kim May 29 '15 at 09:18
