Ionic2-LiveReload无法正常工作

Question

I'm trying to run a brand new Ionic2 application on my Android device with --livereload option but I'm getting errors.

Setup commands:

$ ionic start ionic2-speed-test-run --v2
$ cd ionic2-speed-test-run/
$ cordova platform add android

If I do:

$ ionic run android

The application runs properly on my Android device, but if I do:

$ ionic run android -l

Then I get the followin error output:

$ ionic run android -l

Any idea on how to make the --livereload works?

Answer 1

This type of error happens when you are already using live-loading with same ip address. just kill other running ionic apps and try your luck.

if you still get this error just restart system and try it again.

last but least

upgraded my cordova and ionic to latest versions then its working great. just treat it as last hope.

i have used last option for my ionic app.

Answer 2

This message happen when live reload url already in use. Might be you are running $ ionic serve command and try to $ ionic run android -l Close all running program and try again. If problem not resolve, try with restart you system. It will forcefully close your all application. You may try with downgrade Ionic to version 2.
