Android Question How to get the filename to save in database using camera with intent

[Colin Evans]

Hi, I'm trying to work out how to get the filename of the saved camera image using the camera intent example but using the amended code I would have thought it would save in the 'imagefolder - being folder '/storage/emulated/0/Android/data/b4a.example3/files/shared' but it doesn't and the file saves as '/storage/emulated/0/camera/IMG_20211112_103349_0.jpg' I've dropped the code below but I just can't figure out a way of saving the image to the imagefolder I wish them to be in.

#Region  Project Attributes 
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName: 
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
    #BridgeLogger: True
#End Region

#Region  Activity Attributes 
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    Private ion As Object
    Private const tempImageFile As String = "tempimage.jpg"
    Private lastPicture As Bitmap
    
End Sub

Sub Globals
    Private ImageView1 As ImageView
    Public imageFolder As String
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")
    imageFolder = Starter.rp.GetSafeDirDefaultExternal("shared")
    If lastPicture.IsInitialized Then ImageView1.Bitmap = lastPicture
    Log("folder " & imageFolder)
End Sub

Sub Button1_Click
    TakePicture
End Sub

Sub TakePicture
    Dim i As Intent
    i.Initialize("android.media.action.IMAGE_CAPTURE", "")
    File.Delete(imageFolder, tempImageFile)
    Log("folder " & imageFolder)
    Dim u As Object = Starter.provider.GetFileUri(tempImageFile)
    i.PutExtra("output", u) 'the image will be saved to this path
    Try
        StartActivityForResult(i)
    Catch
        ToastMessageShow("Camera is not available.", True)
        Log(LastException)
    End Try
End Sub

Sub ion_Event (MethodName As String, Args() As Object) As Object
    If Args(0) = -1 Then
        Try
            Dim in As Intent = Args(1)
            If File.Exists(imageFolder, tempImageFile) Then
                lastPicture = LoadBitmapSample(imageFolder, tempImageFile, ImageView1.Width, ImageView1.Height)
                ImageView1.Bitmap = lastPicture
                File.Delete(imageFolder, tempImageFile) '<-----------------------
            Else If in.HasExtra("data") Then 'try to get thumbnail instead
                Dim jo As JavaObject = in
                lastPicture = jo.RunMethodJO("getExtras", Null).RunMethod("get", Array("data"))
            End If
        Catch
            Log(LastException)
        End Try
    End If
    If lastPicture.IsInitialized Then ImageView1.Bitmap = lastPicture
    Log("folder " & imageFolder)
    Return Null
End Sub

Sub StartActivityForResult(i As Intent)
   Dim jo As JavaObject = GetBA
   ion = jo.CreateEvent("anywheresoftware.b4a.IOnActivityResult", "ion", Null)
   jo.RunMethod("startActivityForResult", Array As Object(ion, i))
End Sub

Sub GetBA As Object
   Dim jo As JavaObject
   Dim cls As String = Me
   cls = cls.SubString("class ".Length)
   jo.InitializeStatic(cls)
   Return jo.GetField("processBA")

Better code for camera intent: https://www.b4x.com/android/forum/threads/b4x-b4xpages-intent-based-camera.120721/

You cannot force the camera app to save the image in any specific folder.
You can save the bitmap yourself.
