[ERROR] Cordova encountered an error.
        You may get more insight by running the Cordova command above directly.

[ERROR] An error occurred while running cordova emulate android (exit code 1).

Any idea on what's happenning? Same error ocurrs with another ionic application(this new blank one is a test to check the problem was not caused by myself). Same error happens when running ionic cordova run android

• ionic 3.1.2
• cordova 7.0.1
• npm 3.10.9

UPDATE: added ionic info output

global packages:

    @ionic/cli-utils : 1.1.2
    Cordova CLI      : 7.0.1
    Ionic CLI        : 3.1.2

local packages:

    @ionic/app-scripts              : 1.3.7
    @ionic/cli-plugin-cordova       : 1.1.2
    @ionic/cli-plugin-ionic-angular : 1.1.2
    Ionic Framework                 : ionic-angular 3.2.1

System:

    Node       : v7.1.0
    OS         : Windows 8.1
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed

ionic info warned me there were some updates, which ended up in new configuration:

global packages:

    @ionic/cli-utils : 1.3.0
    Cordova CLI      : 7.0.1
    Ionic CLI        : 3.3.0

local packages:

    @ionic/app-scripts              : 1.3.7
    @ionic/cli-plugin-cordova       : 1.3.0
    @ionic/cli-plugin-ionic-angular : 1.3.0
    Cordova Platforms               : android 6.2.3
    Ionic Framework                 : ionic-angular 3.2.1

System:

    Node       : v7.1.0
    OS         : Windows 8.1
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed

Error persists after updating.

Tried ionic cordova run android --livereload but the result's the same.

Answer 1

This should work:

ionic cordova run android --livereload
