Hi and thanks @Biswajit, cool library! Is there a way to add gif files too?

Biswajit · Aug 25, 2023

No. You can convert the GIF to a video and use it.

Tico.13 · Aug 28, 2023

Thanks @Biswajit , im getting this errors trying to use DirAssets:

Line code:

sc.items.Add(CreateMap("data":"Item 1-"&j, "video":File.Combine(File.DirAssets, "video.mp4"), "type":"file"))

com.google.android.exoplayer2.upstream.FileDataSource$FileDataSourceException: com.google.android.exoplayer2.upstream.FileDataSource$FileDataSourceException: java.io.FileNotFoundException: /video.mp4: open failed: ENOENT (No such file or directory)

And DirRootExternal:

Line code:

sc.items.Add(CreateMap("data":"Item 1-"&j, "video":File.Combine(File.DirRootExternal&"/", "VID-20210504-WA0001.mp4"), "type":"file"))

com.google.android.exoplayer2.upstream.FileDataSource$FileDataSourceException: com.google.android.exoplayer2.upstream.FileDataSource$FileDataSourceException: java.io.FileNotFoundException: /storage/emulated/0/VID-20210504-WA0001.mp4: open failed: EACCES (Permission denied)

Hi @Biswajit and Thanks for the Library, is very good.

Is it possible to enable normal Zoom instead of Pinch zoom?
