I recently upgraded a project from Cordova 2.2 to 3.5, and can't get any of the plugins to work. I have followed all the instructions for using the CLI to build the project and add plugins (as described here), and have checked that the config files and cordova_plugins.js are correct (as explained here). My required plugs are the media (audio) and Power plugins (the latter to delay powerdown) - neither appeared to be working so I also added a 'simpler to test' Device plugin to see if I could read the device type. That doesn't work either so it appears all my plugins are failing. I am calling the code as follows:
var beep = new Media("/android_asset/www/res/beep_mp3.mp3");
beep.play();
and
chrome.power.requestKeepAwake("display");
Testing on Android 4.4.2
