HTTPPostを使用してインターネットと対話するためにASYNCタスクを使用しています...これがJavaコードです

private void viewMyprofile(String username) {
    System.out.println("in view my profile");
    class HttpGetAsyncTask extends AsyncTask<String, Void, String>{
        @Override
        protected String doInBackground(String... params) {
            String lUsername = params[0];

            HttpClient client = new DefaultHttpClient();
            HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
            HttpResponse response;
           // JSONObject json = new JSONObject();
            System.out.println("in do in background");
            try{
                HttpPost post = new HttpPost(URL);
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                nameValuePairs.add(new BasicNameValuePair("username", lUsername));
                nameValuePairs.add(new BasicNameValuePair("stringdata", "Hi"));
                post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                response = client.execute(post);
                /*Checking response */
                if(response!=null){
                    InputStream in = response.getEntity().getContent(); //Get the data in the entity 
                    jsonResponse = convertStreamToString(in);
                    System.out.println("this is my response = " + jsonResponse);
                    return jsonResponse;
                }
            }
            catch(Exception e){
                e.printStackTrace();
            }
            return null ;
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);

            try {
                JSONArray jsonArray = new JSONArray(result);
                Log.i(MyProfile.class.getName(),
                    "Number of entries " + jsonArray.length());
                for (int i = 0; i < jsonArray.length(); i++) {
                  JSONObject jsonObject = jsonArray.getJSONObject(i);
                  Log.i(MyProfile.class.getName(), jsonObject.getString("password"));
                  textView.setText(jsonObject.getString("password"));
                }
              } catch (Exception e) {
                e.printStackTrace();
              }
        }
    }

    HttpGetAsyncTask httpGetAsyncTask = new HttpGetAsyncTask();
    // Parameter we pass in the execute() method is relate to the first generic type of the AsyncTask
    // We are passing the connectWithHttpGet() method arguments to that
    httpGetAsyncTask.execute(username);
    System.out.println("after execution call");
}

public static String convertStreamToString(InputStream is) throws Exception {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();
    String line = null;

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

    is.close();

    return sb.toString();
}

}

これらは2つのlogcat行です...

ご覧のとおり、応答文字列をjson配列に変換する際にエラーが発生しています...助けてください...

出力ログによると、配列を取得していません。1 つの JSONObject を取得しています。これだけ...

try {
     JSONObject jsonObject = new JSONObject(result);
     Log.i(MyProfile.class.getName(), jsonObject.getString("password"));
     textView.setText(jsonObject.getString("password"));
} catch (Exception e) {
     e.printStackTrace();
}

ログに記録し、textView のテキストを umairisback に設定する必要があります
