MediaPlayerStream and position seekbar?

[tuhatinhvn]

Can i use MediaPlayerStream and position seekbar ?

after 100% loading , can i get current positon of MediaPlayerStream??

 

[Erel]

No. MediaPlayer doesn't support it.

 

[tuhatinhvn]

i saw some app can play stream and support move seekbar

I think B4A can make it??

I dont want to download complete and use mediaplayer to play it

Because some mp3 file very large(ex: nonstop mp3 ^^)

Do you have any idea Erel man???

I guess that they manage the audio stream internally. MediaPlayer doesn't support it.

here is an example of android media player streaming code which also support seekbar(position).
