VideoListDemoActivity - Immediate notifyDataSetChanged

[jmgirven]

I have included a slight variation of the example code from VideoListDemoActivity in my app. In my case, VideoListFragment is initialised with some cached content, and simultaneously a request is made to update to the latest set of videos. This can come back relatively quickly, whilst the cached video thumbnails are still in some form of loading state (Usually "1) The view has not yet been created"). When the new data is returned, I call notifyDataSetChanged on the adapter. Sometimes this will cause an IllegalStateException:

java.lang.IllegalStateException: Not connected. Call connect() and wait for onConnected() to be called.

I have managed to reproduce this consistently in my version. If I stop the notifyDataSetChanged, or even delay it by 0.5 seconds, there is no crash. Can you reproduce this too? Any suggestions what I should do in this case?

Thanks, Jon.

My initial diagnosis of notifyDataSetChanged being called too soon was close. I had introduced a check to see if a view was being reused in the list for a different thumbnail. This occasionally led me to call "thumbnail.initialize" on a view that was being initialised. I believe this is where the error originates from. Avoiding this check has stopped the crash.

Thanks this helped me a lot, introducing a simple check solved my issues

Could anyone please post a sample code for the fix or elaborate on it. Sadly, this discussion leads me nowhere. Thanks.

I have the same problem "YouTubeThumbnailView Not connected. Call connect() and wait for onConnected() to be called" in RecyclerView.Adapter by scrolling quickly and there are 3 youtube thumbnails in the recylerView.

In the adapter I put like this: a field: private boolean readyForLoadingYoutubeThumbnail = true; and at onBindViewHolder

 */
Log.d(TAG, "readyForLoadingYoutubeThumbnail" + readyForLoadingYoutubeThumbnail);
final YouTubeInitializationResult result = YouTubeApiServiceUtil.isYouTubeApiServiceAvailable(activity);
if (readyForLoadingYoutubeThumbnail) {
    Log.d(TAG, "initializing for youtube thumbnail view...");
    readyForLoadingYoutubeThumbnail = false;
    holder.youTubeThumbnailView.initialize("aaaaaaaaaa", new YouTubeThumbnailView.OnInitializedListener() {
        @Override
        public void onInitializationSuccess(final YouTubeThumbnailView youTubeThumbnailView, final YouTubeThumbnailLoader youTubeThumbnailLoader) {

            youTubeThumbnailLoader.setVideo(videoId);
            youTubeThumbnailLoader.setOnThumbnailLoadedListener(new YouTubeThumbnailLoader.OnThumbnailLoadedListener(){

                @Override
                public void onThumbnailLoaded(YouTubeThumbnailView childYouTubeThumbnailView, String s) {
                    childYouTubeThumbnailView.setVisibility(View.VISIBLE);
                    holder.relativeLayoutOverYouTubeThumbnailView.setVisibility(View.VISIBLE);
                    youTubeThumbnailLoader.release(); // spy ga memory lick
                }

                @Override
                public void onThumbnailError(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader.ErrorReason errorReason) {
                    youTubeThumbnailLoader.release(); // spy ga memory lick
                }
            });
            youTubeThumbnailView.setColorFilter(Color.rgb(123, 123, 123), android.graphics.PorterDuff.Mode.MULTIPLY);

            readyForLoadingYoutubeThumbnail = true;
        }

        @Override
        public void onInitializationFailure(YouTubeThumbnailView youTubeThumbnailView, YouTubeInitializationResult youTubeInitializationResult) {
            //do nohing.. ada error, tambahin method ini jalan, error-nya lupa...
            readyForLoadingYoutubeThumbnail = true;
        }
    });
}

It is works for me...

@parasjain1 ... i agreed with you...

Sadly, this discussion leads me nowhere

[raedsaeed]

@rudiw wow great solution it worked for me !!

[madhankumardroid]

When I use this solution, the initialize method is called for particular positions only. For example, I have three items per page, when I load that in the recycler view, the initialize method is called only for the 0 position. After pagination, another 3 items received, in that the initialize method is called only for 4 and 5 positions. The initialize method is not called for 1,2 and 3 positions. So, please suggest a solution that works in this scenario.

Perhaps private boolean readyForLoadingYoutubeThumbnail = true; should be added in Viewholder not in adapter. This way next ViewHolder thumbnail initialization won't stop until last viewholder has been initialized.
