I am making an app in which I want the users to record video and upload in it like you tube. I am able to record the video and also upload it to the firebase storage but I am unable to load the uploaded video in the video view. Whenever I run the app I get only to see the black screen. Here is my code

private var path = "https://firebasestorage.googleapis.com/v0/b/video-app-af9bf.appspot.com/o/Videos%2FVideo_20200812_141638_.mp4?alt=media&token=d87f94e0-6ca3-4de2-856c-b228884185f7"


    val view = fragmentview.findViewById<VideoView>(R.id.v)
    val uri = Uri.parse(path)
    view.setVideoURI(uri)
    view.requestFocus()
     view.start();




This is my xml file

What I have tried:

I am trying to display video from firebase storage to video view using url.

1 solution

To start with:
Make sure that video in Storage is actually in a format that Android devices can play. VideoView can play only the types of videos that Android supports[^].
private var path = "https://firebasestorage.googleapis.com/v0/b/video-app-af9bf.appspot.com/o/Videos%2FVideo_20200812_141638_.mp4?alt=media&token=d87f94e0-6ca3-4de2-856c-b228884185f7"
val view = fragmentview.findViewById<VideoView>(R.id.v)
val uri = Uri.parse(path)
view.setVideoURI(uri)
view.requestFocus()
 view.start();

You are passing the uri directly into the VideoView. This would mean you are trying to stream the video from the given uri. Firebase Storage doesn't support video streaming, thus the issue. Streaming from a uri requires that the server on the other end be able to stream the given resource.

Since you want to play a video from Storage, you'll have to:
1. download the entire file first
2. save it to a local storage
3. then pass this local storage file path to the VideoView for playback.

For an easy test, pass the hard coded local url to your VideoView and see for yourself.

Try out.

But when I have tried it in another activity then it worked properly

As shared, if tis is streaming it wouldnt. Believe the other activity would be an image or a media that is locally downloaded.

Sir actually I am a beginner and I learnt programming from you tube and I want someone help to solve some coding problems. Can I contact you personally through Instagram or messenger

Sorry, I don't use them. You need to learn yourself and ask for queries using this forum only. People who can help will answer.
