video player studio mp4

Question

I would like to play a video in a dialog window, but it doesn't work. The video is instead of the "raw" directory. I don't know where I'm wrong. Can you help me Please? There is the code

ImageButton video_player = (ImageButton) findViewById(R.id.img_btt_on_ear_watch);
        video_player.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                final Dialog dialog = new Dialog(context);
                dialog.setContentView(R.layout.layout_video_player);

                String filePlace = "android.resource://" + getPackageName() + "/" + R.raw.grado_video_cuffie_making;
                VideoView videoV = (VideoView) findViewById(R.id.vv_video_player);
                Uri videoURI = Uri.parse((String) filePlace);
                videoV.setVideoURI(videoURI); //this is the 128 raw
                videoV.setMediaController(new MediaController(context));
                videoV.start();

                ImageButton dialogButton = (ImageButton) dialog.findViewById(R.id.img_btt_vv_close);
                // if button is clicked, close the custom dialog
                dialogButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        dialog.dismiss();
                    }
                });

                dialog.show();

            }
        });

There is the Logcat

This error says that the `videoV` variable is null, you therefore get a NullPointerException. Check that in `layout_video_player.xml`, you have a VideoView with the ID `vv_video_player` : if not, that would cause the `findViewById` function to return null — MeanStreet, Nov 15 '17 at 09:54
the VideoView ID is correct and I have it in the layout_video_player.xml — Twing90, Nov 15 '17 at 09:56
This will search in the IDs of the ImageButton actually, try `dialog.findViewById(...)` instead — MeanStreet, Nov 15 '17 at 10:00

Use this

 VideoView videoV = (VideoView) dialog.findViewById(R.id.vv_video_player);

insted of this

VideoView videoV = (VideoView) findViewById(R.id.vv_video_player);
