私の登録 AsyncTask は正常に動作し、私のデータは PHP MYSQL で正常に動作していますが、例外に直面しています。
public class SignupJson extends AsyncTask<String,String,String> {
//SignupJSONParser sjson = new SignupJSONParser();
JSONObject json = new JSONObject();
//private static final String TAG_SUCCESS = "success";
HttpParams mhttpparams = new BasicHttpParams();
@Override
protected void onPreExecute() {
pDialog = new ProgressDialog(SignupActivity.this);
pDialog.setMessage("Creating Account..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
super.onPreExecute();
}
@Override
protected String doInBackground(String... args) {
String getName = _Name.getText().toString();
String getEmail = _Email.getText().toString();
String getPassword = _Password.getText().toString();
List<NameValuePair> pair = new ArrayList<NameValuePair>();
pair.add(new BasicNameValuePair("name",getName));
pair.add(new BasicNameValuePair("id",getEmail));
pair.add(new BasicNameValuePair("pass", getPassword));
// int success=0;
json = JSONParser.makeHttpRequest( URL,"POST", pair);
Log.d("Create Response", json.toString());
try {
String success = json.getString(TAG_SUCCESS);
//success = json.getInt(TAG_SUCCESS);
if (json.getString(TAG_SUCCESS)!=null) {
if (Integer.parseInt(success)==1)
{
Log.d("User Created!", json.toString());
Intent login = new Intent(getApplicationContext(), LoginActivity.class);
startActivity(login);
// closing this screen
finish();
//return json.getString(TAG_MESSAGE);
}
else {
Log.d("Registration Failure!", json.getString(TAG_MESSAGE));
return json.getString(TAG_MESSAGE);
}
}
} catch (JSONException e) {
e.printStackTrace();
// success=0;
}
return null;
// return ""+success;
}
@Override
protected void onPostExecute(String s) {
pDialog.dismiss();
if (json != null){
Toast.makeText(getApplicationContext(),"Registration Done",Toast.LENGTH_SHORT).show();
//Toast.makeText(MainActivity.this, json.toString(), Toast.LENGTH_LONG).show();
}
}
}
}

回線エラー
String success = json.getString(TAG_SUCCESS);
//success = json.getInt(TAG_SUCCESS);
if (json.getString(TAG_SUCCESS)!=null) {
}
このエラーを解決する方法を教えてください。また、PHP Wamp サーバーとの接続が成功した場合と失敗した場合のサーバー応答の処理方法を教えてください。
