Bugando Activity + Memory Error

Question

Good afternoon programmers, I am developing an application and in a certain part of it I populate textviews with some data coming from a webservice. When ordering data from the webservice in a specific class of everything the object comes complete, however when returning this object the class of the fragment I must popular the object comes incomplete giving some nulls in the textviews, sometimes in all... And then if I rotate the screen . The console returns me an error and gives a crash in the application.

follow the console errors:

It also follows my class searching the object on the webserver:

    this.mCont = m;
}

    asyncINFO async = new asyncINFO();
    async.execute(id);
    return obj;
}

        ObjPizzaria pizzariaInfo = new ObjPizzaria();

        SoapObject resposta = new SoapObject(NAMESPACE, METHOD_NAME_INFO);
        resposta.addProperty("id", id[0]);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(resposta);

        HttpTransportSE transportSE = new HttpTransportSE(URL, 9000);
        String resultado = null;
        JSONArray json = null;
        Base64toBMP imagem = new Base64toBMP();
        try {
            transportSE.call(SOAP_ACTION_INFO, envelope);
            resultado = envelope.getResponse().toString();
            json = new JSONArray(resultado);
            JSONObject jsonObj = json.getJSONObject(0);

            pizzariaInfo.setCep(jsonObj.getInt("CEP"));
            pizzariaInfo.setAval(Float.parseFloat(jsonObj.getString("NOTA")));
            pizzariaInfo.setBairro(jsonObj.getString("BAIRRO"));
            pizzariaInfo.setCidade(jsonObj.getString("CIDADE"));
            pizzariaInfo.setNome(jsonObj.getString("NOME"));

            LatLng ll = new LatLng(jsonObj.getDouble("LAT"), jsonObj.getDouble("LNG"));
            pizzariaInfo.setCoord(ll);
            pizzariaInfo.setEmail(jsonObj.getString("EMAIL"));
            pizzariaInfo.setId(id[0]);
            pizzariaInfo.setLogo(imagem.retornaIMG(jsonObj.getInt("ID_IMG")));
            pizzariaInfo.setLogr(jsonObj.getString("LOGRADOURO"));
            pizzariaInfo.setNumero(jsonObj.getInt("NUMERO"));
            pizzariaInfo.setRefe(jsonObj.getString("REFERENCIA"));
            pizzariaInfo.setSobre(jsonObj.getString("SOBRE"));
            pizzariaInfo.setTelefone(jsonObj.getInt("TELEFONE"));
            pizzariaInfo.setTelefone2(jsonObj.getInt("TELEFONE_2"));
            pizzariaInfo.setUf(jsonObj.getString("UF"));
            obj = new ObjPizzaria();
            obj = pizzariaInfo;
        } catch (IOException e) {
            Log.e("Erro1", e.toString());
        } catch (XmlPullParserException e) {
            Log.e("Erro1", e.toString());
        } catch (JSONException e) {
            Log.e("Erro1", e.toString());
        }

        return obj;
    }

}
}

And the class of the fragment that receives the object:

I’m running everything on a Galaxy J2 (I don’t know if it influences these errors). I’m sorry if it’s obvious, because I’m a layman still on the subject...

Answer 1

The error is simple, exactly what is written java.lang.OutOfMemoryError: Failed to allocate a 2284037732 byte Common error for beginners, you are consuming much more memory than your phone supports, you are loading lots of data from one tip at a time by your web-service.

2284037732 byte is a lot for an app

seen that you are loading an image, the most common mistake is to put many large and not optimized images for phones.

1. Do not load all the data from your database into a single call in the webservice, if it is too much data divide into other endpoints or load data into a few "ex, if it is a list instead of loading all the items in the list press 100 on 100"

2. Do not send images via webservice, just send the absolute path to the URL and use libraries as Picasso to display the images

3. Optimize images to the maximum size possible.
