So far I can retrieve an image from the database and show it in an imageview. I would like to have the default image viewer display the image so that I can zoom and pan the image without writing the code myself. Can this be done without first writing the image to a file as the 'iIntent.Initialize() requires?
Thanks.
This is what I'm working with - once record is retrieved:

This is what I'm working with - once record is retrieved:
B4X:
Dim csr As Cursor
Dim Buffer() As Byte
Dim imageData As image 'custom type
imageData.Initialize
imageData.rec_id = csr.GetString("id")
imageData.wNum = csr.GetString("woNum")
imageData.iName = csr.GetString("imageName")
imageData.iData = csr.GetBlob("imageData")
imageData.iText = csr.GetString("imageText")
Buffer = imageData.iData
Dim InputStream1 As InputStream
InputStream1.InitializeFromBytesArray(Buffer, 0, Buffer.Length)
Dim Bitmap1 As Bitmap
Bitmap1.Initialize2(InputStream1)
InputStream1.Close
'intent requires a file - I'd like to provide image as a stream or bitmap etc..
Dim iIntent As Intent
iIntent.Initialize(iIntent.ACTION_VIEW,"file://" & File.Combine(File.DirRootExternal, "PF_Pic.jpg"))
iIntent.SetType("image/jpeg")
StartActivity(iIntent)
