Current behavior:
After install node, cordova, gulp, bower and ionic, i made a new project with:
ionic start test sidemenu
running this project always throws:

On mobile device, it should ionic loader, then get a white screen for more than 5 secons, and then app apeears.

I try ALL the available templates, with same result

Expected behavior:
mobile app should run whitout blank screen or unexpected delays.

Steps to reproduce:

1. Install node v7.9.0
2. npm install -g ionic cordova gulp bower
3. ionic start testproject runtime
4. cd runtime
5. ionic add platform android
6. ionic run android

Thanks for opening an issue with us.
When running ionic run android, it uses the angular JIT compiler, which is fast, but lacks on performance side.
Try running ionic run android --prod to utilise the AOT compiler, which is slow, but creates a smaller bundle, and generally comes with great performance benefits.

If you do the above, and you find there is still a problem with startup speed, please write your android device's model and android version.

@macklus, apart from --prod consider also creating a "splash" screen in your index.html file.

Adding something like "Loading..." and a spinner can improve UX.

Hello, all! @AmitMY is correct here. By default ionic run android does a dev build which uses the Angular JIT mode and does not do any minification or optimizations. This mode, while it builds fast and is great for debugging, is slow to start up and creates very large bundles. For the best on-device testing experience, especially with bigger apps, I would recommend doing a prod build. As @AmitMY mentions, our production build does build a little slower as its runs the Angular AOT compiler, does minification and more, but the end product that it builds starts up much faster.

Hi all !

using --prod seems to be ussefull, so thanks ;-)

I am having this same issue with all my ios builds. In fact, device ready is never fired at all:

export class MyApp {
  rootPage:any = TabsPage;

  constructor(platform: Platform, private storage: Storage, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      console.log('### platform ready ');

Having the same problem on Android when compiling with AOT. The only indication I have in the debug console is:

``
deviceready has not fired after 5 seconds.

main.js:53 Ionic Native: deviceready event fired after 2340 ms
``

I'm a bit confused that I see both of these messages... intuitively I'd think only one of them should be displayed.

Any help?

Hii @AmitMY
I have tried this command ionic run android --prod then i have get this error
Error: Type AddCustomer in /home/serpentcs/IONICprojects/GMS/src/pages/add-customer/add-customer.ts is part of the declarations of 2 modules: AppModule in /home/serpentcs/IONICprojects/GMS/src/app/app.module.ts and AddCustomerModule in /home/serpentcs/IONICprojects/GMS/src/pages/add-customer/add-customer.module.ts! Please consider moving AddCustomer in /home/serpentcs/IONICprojects/GMS/src/pages/add-customer/add-customer.ts to a higher module that imports AppModule in /home/serpentcs/IONICprojects/GMS/src/app/app.module.ts and AddCustomerModule in /home/serpentcs/IONICprojects/GMS/src/pages/add-customer/add-customer.module.ts. You can also create a new NgModule that exports and includes AddCustomer in /home/serpentcs/IONICprojects/GMS/src/pages/add-customer/add-customer.ts then import that NgModule in AppModule in /home/serpentcs/IONICprojects/GMS/src/app/app.module.ts and AddCustomerModule in /home/serpentcs/IONICprojects/GMS/src/pages/add-customer/add-customer.module.ts.

Can you please guide me that what is going wrong on it?

[AmitMY]

While this is not the place for support, it is an easy fix, so I'll explain:
Just reading the error message, disregarding the paths:

AddCustomer is part of the declarations of 2 modules: AppModule and AddCustomerModule.

If AppModule imports AddCustomerModule, remove the decleration from either module.
If it is not, and you are using lazy loading or something, you can also create a new NgModule that exports and includes AddCustomer, then import that NgModule in AppModule and AddCustomerModule

It is such an informative error message.

Okk Thank You

Im having the same problem about deviceready. But it's curious how it throws the error. First time i launch this command: ionic cordova run android -l -c , all runs fine. But after one change on code and performs livereload, im getting this on prompt:

[08:35:22]  console.log: Angular is running in the development mode. Call enableProdMode() to enable the production 
            mode. 
[08:35:22]  console.log: deviceready has not fired after 5 seconds. 
[08:35:22]  console.log: Channel not fired: onPluginsReady 
[08:35:22]  console.log: Channel not fired: onCordovaReady 
[08:35:22]  console.warn: Ionic Native: deviceready did not fire within 5000ms. This can happen when plugins are in an

[08:35:23]  console.log: Ionic Native: deviceready event fired after 5896 ms
