Solution 1

Not sure your design is correct, it looks like you present the user with a list they click and you play. However you only pass the single filename to the video player. If you had the full list you could via completion just keep loading the next file and playing it.

Java

vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        public void onCompletion(MediaPlayer player) {
            Log.i("VideoView", "onCompletion()");

            vv.setVideoPath(next_filename); // the next file in the list 

            vv.start();
            // finish() for closing.
            // finish();
            // vv.requestFocus();


        }

    });

So that's the logic, I would redesign the selection method or remove it.

I dont want to hard code the path by giving setVideoPath();
what the below code does is " it will display the all the videos from the externel storage on the listview and by click on the list the video is going to play"
From the code i am able to display the list of videos, and don't know how to get the list and play the videos one by one? any help

Darren_vms 13-Sep-16 9:07am

Its not hard coding, You already have the call vv.setvideopath() in the code you provided, You present a listview the user selects one of the items. You then load the intent extra and call the intent to play the video. However my passing just the filename of the selected item from the listview you sort of shoot yourself in the foot for playing any more. Why don't you pass the media store ?

Your code looks a lot like http://stackoverflow.com/questions/20007342/how-to-get-list-of-video-files-in-a-specific-folder-in-android have you been working on this for two years ?

/Darren

Darren_vms 13-Sep-16 9:10am

ok so this is the code

http://www.androiddevelopersolutions.com/2013/12/android-play-video-from-sd-card.html

/Darren

sumanth g 13-Sep-16 9:15am

from this code, we can play the video by clicking on that video, what i want to do is, play all the videos in one by one in the present list.

Darren_vms 13-Sep-16 9:24am

keep saying the same thing over and over doesn't make it happen, perhaps you should read up on intents and passing between them.

sumanth g 13-Sep-16 9:12am

hi Darren
i had taken the coded from the stackoverflow and working on it.

Darren_vms 13-Sep-16 9:25am

The code from stackoverflow is only one part and is missing the playing the routine. If you was able to put that together yourself then you can solve this with the pointers I gave

sumanth g 13-Sep-16 9:33am

ok i will into intents. if there is any other options. place a commnet

Darren_vms 13-Sep-16 9:38am

Well that depends on the specs, does the user have to select a video or could they just play one after the other ?

Do you want the application to remember which video has been played and continue from the last one seen ?

I could ask more questions and the answer may change what I recommend.

Is this a pet project or something commercial ?

/Darren

sumanth g 13-Sep-16 9:43am

Is is just pet project not commerical.
It should display all the videos
It should play all the videos one after one
It should remember which video be played and continue to next videos, after playing the last video it should come back to previous menu

hi Darren,
can u help me in doing this android application

Darren_vms 13-Sep-16 11:33am

That is what I thought I had been doing, helping. If you are saying I've been of no help then I guess you are entitled to your opinion. If you are asking me to write the code for you then I would have to decline. If I wrote the code i would rob you of the chance to improve and learn.

The code you found gets you 90% of the way, come on I know you can do it. Read a little, try things, look at the code and understand it.

When you have a pet project and that's the best time to learn, you want something so go out and get it. We are here to ~~help~~ chat, not write the application for you. That would be cheating and take me away from my real job which pays the bills so I can ~~help~~ chat to you on here.

sumanth g 13-Sep-16 13:53pm

Thanks Darren, for your reply.
By using getcount(). i am able to see the no of videos available.By using for loop know i am trying. If it is success i will post the code. or i will place my doubt.

sumanth g 13-Sep-16 14:24pm

Hi darren,
i had testing the code with for loop. i had placed log.d for log view.
i had placed the Log.d("filepath",filepath);
which displays the filepath exactly same as in the path?
but by giving the filepath name directly to the video_player_view.setVideoPath("filepath"); it was unable to play the video. it prompts as unable to play the video. But we i give like this
video_player_view.setVideoPath("/mnt/sdcard/Movies/Videos/abc.3gp"); it is able to play the video.
how to solve this issue?
