Android Question MediaBrowser does not generate Thumbfile.

[Juzer Hussain]

Hi,

I am trying to generate thumbfile of a video on my tablet having android 5.0.1 it says "No media on the device." The media video file is present and it is running also.

m=mb.GetExtVideoFileInfo(File.DirRootExternal & "/SVPS/" & sSelectedFile)
bmp = mb.GetVideoThumbnailByID(m.Get("ID0"),True)

I doubt in Activity_Create i have initialized mb as
If FirstTime Then mb.Initialize("")
and the above code in written in Activity_Resume so i initialize it again in Activity_Resume it didnt work. I removed the intialize statement even that didn't work.

What could be wrong?

Pls guide me.

Please use [code]code here...[/code] tags when posting code.

You should never initialize objects in Activity_Resume.

Is there any error message in the logs?

Are you sure that the system has registered your video file in its database? To be sure, reboot your device.

Hi Erel,

"I just tried initializing MediaBrowser in resume i removed it already."
I am seeing the video file it is running also but its not detected by MediaBrowser in the statement below.

m=mb.GetExtVideoFileInfo(File.DirRootExternal & "/SVPS/" & sSelectedFile)

I am getting follwing error in log-:

MediaBrowser: no media on the device!

Hi Informatix,
Is there any workaround if the file is not registered?
Thanks

The ScanNewMedia function.

Thanks Informatix,

I will try it.

I'm using the MediaBrowser and renaming the file in my program.
When I use the ScanNewMedia function, the renamed file does not appear.

Sub ScanMedia(FolderName As String, FileName As String)
    Dim Folders() As String
    Folders = Array As String(File.Combine(FolderName, FileName))
    MB.ScanNewMedia(Folders)
End Sub

I've also tried sending it only the foldername; foldername and "" for filename; "" for foldername; and file.dirrootexternal & "/DCIM/Camera" with all the mentioned iterations.
All with no results.
Any advice will be appreciated.

I tried the function and it works fine, but it seems there's a delay to record the new name in the media database and thus the change cannot be immediately seen.
When you log File.Combine(FolderName, FileName), is it correct? No problem with upper/lower case?
Note that DCIM/Camera is a folder where you're not supposed to make changes yourself.

Thanks Fred,
Yes, it is the correct folder/filename in the log.
How should one properly rename a file within the DCIM/Camera folder?
Thanks,

The problem when you rename these files is that you interfere with the camera app that stores its files there. Since the camera app is different from a device to another, it is difficult to know what's the impact of such changes.
