Android Question Populating ListView from SQLite table

I am reading all the Images in the Phone Gallery.
I then "filter" these images so that I only write the File Name and Image of files that are less than 8 days old to the SQLite table "gallery".
I write both the File Name and the image (BLOB) to the table "gallery".
I then populate the ListView "lvTip" from the SQLite table "gallery".
I receive the following error on line:
Code: 
PicName = Curs.GetString("picName")
Error:
Code: 
android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
As can be seen from the Log, I do have data in the table "gallery".
Log:
Code: 
Copying updated assets files (8)

If I use:
Code: 
PicName = Curs.GetString2(0)
I get the exact same error.

It is very strange, I am using the same code to populate the ListView that I am using to populate a ListView in another Activity.
The only difference is that I am loading the table in the other Activity from a remote MySQL database using RDC.

Ah, yip that could be it.
I just checked and one image is 2.36 MB - (3120 X 4160 px)
Could I reduce the size of the images before I write into the table?

I'm not seeing the answer but I am seeing that the log and the code do not match.

What I mean is that in the log we can see that only 3 images are written to the database but then we see 'Gallery Rows Count: 4' appearing in the log twice (just a couple of lines apart with a reference to another image that doesn't appear to have been previously processed.

Below you can see what I mean with there being only 3 images written to the database and then a reference to an image not previously processed.

Picture Name: IMG_20170309_121014.jpg
Number of Days: 6
InsertMaps (first query out of 1): INSERT INTO [gallery] ([picName], [galleryPic]) VALUES (?, ?)List: (ArrayList) [{picName=IMG_20170309_121014.jpg, galleryPic=[B@1446a0c}]

Click to expand...

If there are only 3 images being sent to the database then how does Gallery Rows Count show 4?
The two instances of 'Gallery Rows Count' is hinting at the possibility that the sub LoadPictures is being invoked multiple times perhaps???

I tried CreateScaledBitmap and it is working.
If I run this:
Code: 
                Dim bmp As Bitmap
                Dim NewWidth As Int
                Dim NewHeight As Int
                bmp.Initialize("/storage/emulated/0/DCIM/Camera/",MyPictureName)
                Log("BMP width: " & bmp.Width)
                Log("BMP height: " & bmp.Height)
                NewWidth = bmp.Width / 10
                NewHeight = bmp.Height / 10
              
                CreateScaledBitmap(bmp, NewWidth, NewHeight)
              
                Log("Scaled BMP width: " & bmpNEW.Width)
                Log("Scaled BMP height: " & bmpNEW.Height)
I get:
Code: 
BMP width: 1344
BMP height: 2240
Scaled BMP width: 134
Scaled BMP height: 224
Which is correct.

I now need to write this bmpNEW to an InputStream.
I have tried:
Code: 
Dim InputStream1 As InputStream
InputStream1 = bmpNEW
But get an error:
Code: 
java.lang.IllegalArgumentException: method anywheresoftware.b4a.objects.streams.File.Copy2 argument 1 has type java.io.InputStream, got android.graphics.Bitmap

Normally I would do:
Code: 
InputStream1 = File.OpenInput(File.DirRootExternal, "Test.png")
when reading from a file.
How would I write bmpNEW into InputStream1?

Thanks, sorted:
Code: 
   Dim out As OutputStream
   out.InitializeToBytesArray(0)
   bmpNEW.WriteToStream(out, 100, "JPEG")
   out.Close
   Buffer =  out.ToBytesArray
