Загрузка данных о пользователе в Async Task через API Appwrite
Хочу как-то переформатировать код в Async Task чтобы сначала данные загружались с облака Appwrite, а уже после этого они высвечивались в виджетах. Дело в том, что код снизу выполняет задачу, но если пользователь будет постоянно тыкать на профиль, то приложение вылетит. Да и вообще, такие вещи нужно оформлять через Async Task.
Я пытался сделать это с помощью AsyncTask самостоятельно, разделив части на doInBackground()
и onPostExecute(). Но почему-то данные не загружались в виджеты. В идеале чтобы ответ был с объяснением.
Вот код который без AsyncTask
