How to call the onCreate method of Java class in Angular js using Ace cordova Plugin?

[Mukesh-logn]

I am trying to call the public void onCreate(Bundle savedInstanceState) method using plugin cordova-plugin-ace but I am getting the run time exceptions.. cordova.js:314 Uncaught Error: Native error: java.lang.RuntimeException: Error in FullscreenVlcPlayer.onCreate: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.content.Context.getApplicationContext()' on a null object reference at run.ace.Utils.invokeMethodWithBestParameterMatch(Utils.java:378) at run.ace.Utils.invokeMethod(Utils.java:253) at run.ace.IncomingMessages.invoke(IncomingMessages.java:214) at run.ace.NativeHost$2.run(NativeHost.java:242) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:135) at android.app.ActivityThread.main(ActivityThread.java:5930) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1405) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1200)

Following is my angularJs code for invoking the Oncreate method.

 if (window.ace.platform == "Android"){
                var canvas = new window.ace.Canvas();
                var bundle = new ace.NativeObject("android.os.Bundle");
                var obj = new ace.NativeObject("FullscreenVlcPlayer");
                obj.invoke("onCreate",bundle );
                canvas.getChildren().add(obj);

```     var popup = new ace.Popup();
                popup.setPosition(50, 20);
                popup.setRect({x: 50, y: 20, width: 200, height: 200});
                popup.setContent(obj);

       }

Following is my java class.
FullscreenVlcPlayer.java
`

public class FullscreenVlcPlayer extends Activity implements  SurfaceHolder.Callback, IVideoPlayer {
        private  String              urlToStream;
        private LinearLayout        vlcContainer;
        private SurfaceView         mSurface;
        private SurfaceHolder       holder;
        private FrameLayout         vlcOverlay;
        private ImageView           vlcButtonPlayPause;
        private Handler             handlerOverlay;
        private Runnable            runnableOverlay;
        private Handler             handlerSeekbar;
        private Runnable            runnableSeekbar;
        private SeekBar             vlcSeekbar;
        private TextView            vlcDuration;
        private TextView            overlayTitle;
        private LibVLC              libvlc;
        private int                 mVideoWidth;
        private int                 mVideoHeight;
        private final static int    VideoSizeChanged = -1;   
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            urlToStream = "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov";// b.getString("url", null);

        getActionBar().hide();

            // SETUP THE UI
            try{
                getActionBar().hide();
                setContentView(R.layout.activity_fullscreen_vlc_player);
                }catch(Exception e){
                Log.d("TAG", "error");
            }

            // VLC
                vlcContainer = (LinearLayout) findViewById(R.id.vlc_container);
                mSurface = (SurfaceView) findViewById(R.id.vlc_surface);

            // OVERLAY / CONTROLS
                vlcOverlay = (FrameLayout) findViewById(R.id.vlc_overlay);
                vlcButtonPlayPause = (ImageView) findViewById(R.id.vlc_button_play_pause);
                vlcSeekbar = (SeekBar) findViewById(R.id.vlc_seekbar);
                vlcDuration = (TextView) findViewById(R.id.vlc_duration);

                overlayTitle = (TextView) findViewById(R.id.vlc_overlay_title);
          //  overlayTitle.setText("rtsp://172.22.68.96:21212/Stream-2");

            // AUTOSTART
                playMovie();

        }
    }
