Я новичок в мире разработки, так что вы можете определить, в чем здесь проблема?

Answer 1

Хорошо, забавная вещь. Когда я добавил блок catch для platform.ready обещание - проблема ушла.

    platform.ready().then(() => {

        .....

        console.log('---READY---');
        splashScreen.hide();

    })
    .catch((err)=> {

        console.log('ERROR: ', err);

    });

Я надеялся увидеть причину ошибки, но моя консоль кристально чистая. Буду признателен, если кто-нибудь сможет объяснить этот феномен.

Спасибо.

Answer 2

Обычно это происходит, когда какой-то код в вашем приложении выдает ошибку при запуске, которая приводит к разрыву приложения. Это может быть несовместимый плагин или какая-то другая функция, которая иногда дает сбой. Запустите отладочную сборку и проверьте консоль на наличие ошибок. Вы также можете опубликовать вывод ionic info и проверить, все ли требования к плагинам выполнены.

Answer 3

То, что вы дали, недостаточно, но вы включили режим prod в main.ts? Если не измените ваш main.ts ниже

    import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; 
import { AppModule } from './app.module'; 
import {enableProdMode} from "@angular/core";
 enableProdMode();
 platformBrowserDynamic().bootstrapModule(AppModule);
