--------------------------------

             Summary: Media Plugin throws Null Pointer Exception - Android 4.4.2
                 Key: CB-6144
                 URL: https://issues.apache.org/jira/browse/CB-6144
             Project: Apache Cordova
          Issue Type: Bug
          Components: Plugin Media
    Affects Versions: 3.3.0
         Environment: Android 4.4.2 - Nexus 7
            Reporter: Ashwin Desai


Here's my scenario 

1) Start Recording using the Media plugin
2) Continue for 1 minute
3) Stop recording and confirm that the file exists on the sdcard. 
4) call media.play() to play the file recorded in steps 1 - 3.
5) The plugin throws a Null Pointer Exception.

/**
     * attempts to initialize the media player for playback
     * @param file the file to play
     * @return false if player not ready, reports if in wrong mode or state
     */
    private boolean readyPlayer(String file) {
        if (playMode()) {
            switch (this.state) {
                case MEDIA_NONE:
                    if (this.player == null) {
                        this.player = new MediaPlayer();
                    }
                    try {
                        this.loadAudioFile(file);
                    } catch (Exception e) {
                        this.handler.webView.sendJavascript("cordova.require('org.apache.cordova.media.Media').onStatus('"

                    }
                    return false;
                case MEDIA_LOADING:
