Exo Player 2 implementation on a listview
I'm trying to create a newsfeed, something similar to Facebook/Instagram where there are text only posts, Image posts and also Video posts. Image and text posts load fine, the problem I am facing at the moment is on the Video part.
If the post is a video I am able to show the ExoVideoview with the video loaded in it works well for the first time I populate the listview. The issue is that,
When I scroll down one or two positions down and come back to the top the video is unplayable. But if scroll down atleast 10 positions and come back it starts to play.
When I move out to the second position the top video keeps playing and at certain times only the audio is playing. I understand this might be cause the player isn't released properly which I would like to know what the best way is to release it.
Any help would be really appreciated as I could't find any proper solution on the internet for this for the past few days. Attached the code for the Adapter below.
public mlibraryAdapter(Context mContext, List<newsfeedSetter> list, ArrayList<String> userids, ArrayList<String> postids, ArrayList<String> b_ids, ArrayList<String> o_spid)
{
this.mContext = mContext;
this.feedlist = list;
this.user_id = userids;
this.post_id = postids;
this.bids = b_ids;
this.o_s_pid = o_spid;
fillfeed();
}
@Override
