The mysterious entity lurking within the depths of Java Script Ionic framework, forever

For my Ionic framework iOS and Android Media service, I used the Cordova Media plugin. When initializing and playing a media object in JavaScript, I encountered an undefined object error.

var self  = {
'currentTrack': null,
'initPlayer': function (videoID) {
self.currentTrack = Media(IP_ADDRESS + 'stream/'+videoID);
console.log('initd');
},
'Play': function () {
console.log(self.currentTrack);

    self.currentTrack.play();
}
};

In the template, I initialized the audio player like this:

<ion-content ng-init="audioPlayer.initPlayer('foo')>

And declared the play function for a button:

<button ng-click="audioPlayer.Play()"

The error message received was:

Error: undefined is not an object (evaluating 'self.currentTrack.play')

Answer №1

When developing your app in a browser, Cordova plugins may not function properly until the app is built and running on a device. Utilize the remote debugging tool to troubleshoot issues with ".apk" or ".ipa" files. For more information on remote debugging, visit this link.

Remember the following key points:

  1. Make sure all code is triggered on the deviceready event.
  2. The cordova.js file should be the first JavaScript file loaded in your project.

Answer №2

My function within the deviceready event was not properly declared before. Everything is functioning correctly now.
