very slow startup time with ionic 2.0.0 final

[coolman7]

Short description of the problem:

Android apps created with Ionic 2.0.0 final that starts very slow: about 15-25 seconds depending on phone processor speed. I get following message at console:

Native: deviceready did not fire within 5000ms. This can happen when plugins are in an inconsistent state. Try removing plugins from plugins/ and reinstalling them.
main.js:6097 DEVICE READY FIRED AFTER 8108 ms

What behavior are you expecting?

5-7 seconds of startup time

Steps to reproduce:

1. ionic start test --v2
2. cd test
3. ionic platform add android
4. ionic build android --prod
5. Change main.ts file as this and repeat step 4. Both scenarios gave same result:

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

I added modified as these:

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

Which @ionic/app-scripts version are you using?

Hi @coolman7,

We are well aware of the issue and are working hard on fixing it. You're running the build correctly.

Please make sure you have the latest ionic cli.

npm uninstall -g ionic
npm install -g ionic@latest

sudo may be required depending on your environment.

Thanks,
Dan
