Out Of Memory String Android

I get huge JSON, and while I'm reading OutOfMemoryError lines.

Here is my first method that I am trying to parse JSON.

    InputStream in = response.getEntity().getContent();
    BufferedReader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"), 8);
    String result = "";

    while (true) {

                String ss = reader.readLine();
                if (ss == null) {
                        break;
                }
                result += ss;
   }

And I also tried this method.

    InputStream in = response.getEntity().getContent();
    BufferedReader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"), 8);
    StringBuilder sb = new StringBuilder();
    String line = null;

    while ( (line = reader.readLine()) != null)
    {
    sb.append(line);
    }

In both cases, OutOfMemoryErorr appears.

The best solution I have found is to raise a bunch of application.

I placed android:largeHeap="true"under <application/>in AndroidManifest.xml.

Mostly the error is due to the size of the heap. You need to increase heap size

JSON , . , .

// try to get formattedAddress without reading the entire JSON
        String formattedAddress;
        while ((read = in.read(buff)) != -1) {
            jsonResults.append(buff, 0, read);
            formattedAddress = ((String) ((JSONObject) new JSONObject(
                    jsonResults.toString()).getJSONArray("results").get(0))

JSONObject statusObj = new JSONObject(jsonResults.toString());
        String status = (String) (statusObj.optString("status"));
        if (status.toLowerCase().equals("ok")) {
            formattedAddress = ((String) ((JSONObject) new JSONObject(
                    jsonResults.toString()).getJSONArray("results").get(0))
                    .get("formatted_address"));
            if (formattedAddress != null) {
                Log.w("Taxeeta", "Did not saved memory, returned late from json") ;
                return formattedAddress;
