Startup long in android for ionic 3

Hello,

Yesterday I migrated to ionic 3.
To do this I first migrated to next version of the cli. Then I removed my node_module and update my package.json before running the npm install ( I also removed the package.json.lock)

But now the startup of my app is really long…
First my build prod faced lot of issues ( I was obliged to increase the node build to 8192)

Anyway now I am using latest of everything:


cli packages: (c:\Users\AppData\Roaming\npm\node_modules)

    @ionic/cli-utils  : 1.18.0
    ionic (Ionic CLI) : 3.18.0

    cordova (Cordova CLI) : 7.0.0

    },

TO build I use command:

ionic cordova run android --prod

Before I just used ionic run android --prod

What is strange is that after the 10 minutes of build when I start my app it takes 15 seconds to start (like a normal build).
Here are the logs:

vendor.js:3916 Angular is running in the development mode. Call enableProdMode() to enable the production mode.
main.js:18000 Home displayed
main.js:18045 Not authenticated so redirect to connection
cordova.js:1223 deviceready has not fired after 5 seconds.
vendor.js:164568 Ionic 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.
(anonymous) @ vendor.js:164568
t.invokeTask @ polyfills.js:3
r.runTask @ polyfills.js:3
e.invokeTask @ polyfills.js:3
i.isUsingGlobalCallback.invoke @ polyfills.js:3
n @ polyfills.js:3
vendor.js:164563 Ionic Native: deviceready event fired after 14300 ms

But what I don’t understand is why the plugins are impacted? Ionic is supposed to be a wrapper? And when I launch the same build on my project in ionic 2 (I kept a backup). Device fire in less than 4 seconds.

Do you have any idea?

Solution found. The advice was correct. Uninstalled everything and reinstall everything and it was ok
