Out of memory exception in gson.fromJson()

Question

I use the following code for converting Json string(strWebserviceResult) to my Object:

EntMyClass entMyClass = gson.fromJson(strWebserviceResult,EntMyClass.c         


        

Answer 1

Try using the fromJson method that takes a JsonReader as input instead. This should allow you to not need the whole input string to be in memory at one time. Here's some sample code:

        final HttpURLConnection c = (HttpURLConnection) url.openConnection();
        final InputStreamReader isr = new InputStreamReader(c.getInputStream());
        final JsonReader reader = new JsonReader(isr);
        final EntMyClass entMyClass = GSON.fromJson(reader, EntMyClass.class);
        reader.close();
        c.disconnect();
