Ionic cordova build android stuck at splashscreen

Question

so I have my app working without errors on web and now I want build android apk file and test it, so I do :

ionic cordova platform add android
ionic cordova build android

I get no erros after these two.

Then I go to the android studio and run android project, build succefull. After I launch my app, i see ionic splashscreen only spinning for 1 second and after that he stops, thats it. Stuck at splashscreen.

console.error :

Answer 1

Open Chrome and go to chrome://inspect/#devices

Then inspect your remote device and check console tab. You're probably facing issues with plugins.

You can also run with

ionic cordova run android -c

This way you can check console on your command.
