Итак, я пытался разработать систему аутентификации для своего приложения.У меня работает REST API, который протестирован для работы с аутентификацией Oauth2 с использованием CURL с моего ноутбука, чтобы я мог получить токены для API.
Моя переменная result в doInBackground действительно получает ответ JSON от моего API, предоставляя информацию о токене доступа, его жизнь и т. Д.
Как будто я получаю это значение в result когда я отлаживаю: {"access_token":"4Oq6o8oAGRf4oflu3hrbsy18qeIfG1","expires_in":36000,"token_type":"Bearer","scope":"read write","refresh_token":"iocSNJ2PTVbph2RnWmcf0Zv69PDKjw"}
Однако мой onPostExecute по какой-то причине не вызывается.
Вот мой код.
login.java
public class Login extends AppCompatActivity {
Button LoginButton, RegButton;
EditText uUserName, uPassWord;
WSAdapter.SendAPIRequests AuthHelper;

uUserName = (EditText) findViewById(R.id.LoginUserBox);
uPassWord = (EditText) findViewById(R.id.LoginPassBox);
//AuthHelper = new WSAdapter().new SendDeviceDetails();
// Moves user to the main page after validation
LoginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// gets the username and password from the EditText
String strUserName = uUserName.getText().toString();
String strPassWord = uPassWord.getText().toString();
// API url duh
String APIUrl = "http://192.168.0.18:8000/auth/token/";
// If the user is authenticated, then transfer to the MainActivity page
