Ionic 2: Cordova is not available. Make sure to include cordova.js or run in a device/simulator (running in emulator)

54

I just set up my first ionic 2 app (I've used ionic 1 fairly extensively). I'm trying to use the ionic-native camera preview plugin.

The setup was pretty straight forward:

npm install -g ionic cordova
ionic start timesnap --v2
ionic platform add android
ionic platform add ios
ionic plugin add cordova-plugin-camera-preview --save

Then I copied and pasted the example code into the about page:

import { CameraPreview, CameraPreviewRect } from 'ionic-native';

// camera options (Size and location)
let cameraRect: CameraPreviewRect = {
  x: 100,
  y: 100,
  width: 200,
  height: 200
};


// start camera
CameraPreview.startCamera(
  cameraRect, // position and size of preview
  'front', // default camera
  true, // tap to take picture
  false, // disable drag
  true, // send the preview to the back of the screen so we can addoverlaying elements
  1 //alpha
);

I launched the app using the following commands:

ionic emulate android -lcs

ionic emulate ios -lcs --target='iPhone-6'

At first the camera just wasn't showing up then I ran chrome://inspect and saw warnings about Cordova missing "try running in an emulator", but this was while running in an android emulator. I tried iOS too and saw the same results.

Any ideas why cordova isn't loading?

Here is the full error log from chrome://inspect while running in an android emulator:

The livereload plugin fails to serve cordova.js file and serves // mock cordova file during development.

FIX: You need go to node_modules/@ionic/app-scripts/dist/dev-server/serve-config.js

and replace

exports.ANDROID_PLATFORM_PATH = path.join('platforms', 'android', 'assets', 'www');

to

exports.ANDROID_PLATFORM_PATH = path.join('platforms', 'android', 'app', 'src', 'main', 'assets', 'www');

This is quite late but anyone going through the same problem might benefit from this answer.First try to add browser by running below command ionic platform add browser and then run command ionic run browser.

which is the difference between ionic serve and ionic run browser?

Ionic serve - runs your app as a website (meaning it doesn't have any Cordova capabilities). Ionic run browser - runs your app in the Cordova browser platform, which will inject cordova.js and any plugins that have browser capabilities

You can refer this link to know more difference between ionic serve and ionic run browser command

Update

From Ionic 3 this command has been changed. Use the command below instead;

ionic cordova platform add browser

ionic cordova run browser

You can find out which version of ionic you are using by running: ionic --version
