如果'userExists'= true，那么它正在运行两位代码

Question

我有这段代码，它将数据发送到Web服务并发送到SQL数据库。在变量设置为true的那一刻，当它应该只执行一个部分时，它会执行两个代码位。我已经尝试了许多不同的方法并彻底调试它，但我似乎找不到解决这个问题的方法。

        if (playerExists) 
    {
        //Update record where equal to username and change the field 'score'
        class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {
            @Override
            protected String doInBackground(String... params) {
                String name = playerName;

                newScore = Integer.toString(existScore + Integer.parseInt(score));

                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

                nameValuePairs.add(new BasicNameValuePair("name", name));
                nameValuePairs.add(new BasicNameValuePair("score", newScore));

                try {
                    HttpClient httpClient = new DefaultHttpClient();

                    HttpPost httpPost = new HttpPost(updateURL);

                    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                    HttpResponse httpResponse = httpClient.execute(httpPost);

                    HttpEntity httpEntity = httpResponse.getEntity();
                } catch (ClientProtocolException e) {
                } catch (IOException e) {
                }
                return "Score Submitted.";
            }

            @Override
            protected void onPostExecute(String result) 
            {
                super.onPostExecute(result);
                Toast.makeText(MainActivity.this, "Score Submitted!", Toast.LENGTH_LONG).show();
            }
        }

        SendPostReqAsyncTask AsyncTask = new SendPostReqAsyncTask();
        AsyncTask.execute(playerName, newScore);
    } else {
        //Just insert score into table
        class SendPostReqAsyncTask extends AsyncTask<String, Void, String> {
            @Override
            protected String doInBackground(String... params) {
                String name = playerName;

                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

                nameValuePairs.add(new BasicNameValuePair("name", name));
                nameValuePairs.add(new BasicNameValuePair("score", score));

                try {
                    HttpClient httpClient = new DefaultHttpClient();

                    HttpPost httpPost = new HttpPost(insertURL);

                    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                    HttpResponse httpResponse = httpClient.execute(httpPost);

                    HttpEntity httpEntity = httpResponse.getEntity();
                } catch (ClientProtocolException e) {
                } catch (IOException e) {
                }
                return "Score Submitted.";
            }

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

                Toast.makeText(MainActivity.this, "Score Submitted!", Toast.LENGTH_LONG).show();
            }
        }

        SendPostReqAsyncTask AsyncTask = new SendPostReqAsyncTask();
        AsyncTask.execute(playerName, score);
    }
