Android Question rescan media

[slydog43]

I'm having trouble with my program that has 2 activities in it. 1st one browses through a database and displays a pic. If I click on the camera button it goes to another activity and takes a picture. the program is the at the picture is not getting updated on my 1st activity. If I end the program and rerun it it shows the new pic. my pics are being stored in \\mypics on the sd card

here are the 3 methods that I tried, but nothing seemed to work.

any ideas (erel?) Does it have to do with storing them in the sd card?

myDir = File.DirRootExternal & "/myPics/"
myPicFilename = "1.jpg"


'send a broadcast intent to the media scanner to force it to scan the saved file.
Dim Phone As Phone
Dim i As Intent
i.Initialize("android.intent.action.MEDIA_SCANNER_SCAN_FILE", _
"file://" & File.Combine(myDir, myPicFilename))
Phone.SendBroadcastIntent(i)
'------------------------------------------------

' Dim i As Intent
' i.Initialize("android.intent.action.MEDIA_MOUNTED", "file://" & File.Combine(myDir, myPicFilename))
' Dim p As Phone
' p.SendBroadcastIntent(i)
'----------------------------------------------

' Dim context As JavaObject
' context = context.InitializeStatic("anywheresoftware.b4a.BA").GetField("applicationContext")
' Dim paths() As String = Array As String(File.Combine(myDir, myPicFilename)) 'files to scan
' Dim mediaScanner As JavaObject
' mediaScanner.InitializeStatic("android.media.MediaScannerConnection")
' mediaScanner.RunMethod("scanFile", Array As Object(context, paths, Null, Null))

Please use [ code ] [ /code ] tags (without spaces) when posting code.

I don't understand how media scanner is relevant here?

I'm trying to display a picture that I just took, say with filename 1.jpg, but that file had already existed in the file system, so it was overwritten. My program still displays the old file until I exit program and rerun it. It will then show the new picture not the old one. I thought the media scanner would solve this, but what do I know.

The media scanner is not relevant. The purpose of the media scanner is to update the image in the phone gallery app.

You should load the image again in your app.
