        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "n");

        Log.e("Buffer Error", "Error converting result " + e.toString());
    }
    // Parse the String to a JSON Object
    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
    }
    // Return JSON String
    return jObj;
}

}

It could be because there is no space provided between 'bearer' and token value in your header . httpPost.setHeader("Authorization","Bearer"+token);

It needs to be Authorization: Bearer <mytoken>

UPDATE

you are setting data values as name-value pairs. You have to set json if content type is json. Check this answer: How to send POST request in JSON using HTTPClient?

You have to set:

 JSONObject holder = getJsonObjectFromMap(params);

//passes the results to a string builder/entity
StringEntity se = new StringEntity(holder.toString());

//sets the post request as the resulting string
httpost.setEntity(se);
