java.lang.NullPointerException

Hello. Can't create object programmatically. What's wrong?

                final VidstaPlayer videoView = new VidstaPlayer(thisActivityContext);
                params = new LinearLayout.LayoutParams(
                        ViewGroup.LayoutParams.MATCH_PARENT,
                        HelpFuncs.getPixelsFromDP(thisActivityContext, 150)
                );
                params.leftMargin = HelpFuncs.getPixelsFromDP(thisActivityContext, 4);
                params.rightMargin = HelpFuncs.getPixelsFromDP(thisActivityContext, 4);
                params.topMargin = HelpFuncs.getPixelsFromDP(thisActivityContext, 4);
                params.bottomMargin = HelpFuncs.getPixelsFromDP(thisActivityContext, 4);
                params.gravity = Gravity.CENTER;
                videoView.setLayoutParams(
                        params
                );
                rootObjectsLL.addView(videoView);

                videoView.setTextColor(Color.WHITE);
                videoView.setVideoSource(Uri.parse(element.getValue()));
                videoView.setFullScreenButtonVisible(true);`
