Android Question Screenshot / Picture

[MarcoRome]

Hi all.
I would like to capture the screen of my app as this:

Now if i combine with button ( Home + another button ) i have this result that you see up.
If i utilize this code:

DateTime.DateFormat = "yyyyMMdd"
    DateTime.TimeFormat = "HHMMSS"
    Dim now As Long = DateTime.now

    Dim filename As String = "BC_" & Starter.NumeroDDT &"_"& now & ".jpeg"
    Dim Obj1, Obj2 As Reflector
    Dim bmp As Bitmap
    Dim c As Canvas
    Obj1.target = Obj1.GetActivityBA
    Obj1.target = Obj1.GetField("vg")
    bmp.InitializeMutable(Activity.Width,Activity.Height)
    c.Initialize2(bmp)
    Dim args(1) As Object
    Dim types(1) As String
    Obj2.target = c
    Obj2.target = Obj2.GetField("canvas")
    args(0) = Obj2.target
    types(0) = "android.graphics.Canvas"
    Obj1.RunMethod4("draw", args, types)
    Dim out As OutputStream
    out = File.OpenOutput(File.DirRootExternal , filename, False)
    bmp.WriteToStream(out, 100, "JPEG")
    out.Close

i have this result:

Any idea ??
Thank you very much
Marco

What are we seeing in this screenshot? The camera preview image?

You can handle the preview event and get the bitmap. Example: https://www.b4x.com/android/forum/t...closed-circuit-tv-cctv-example.23601/#content

Use Canvas to draw over a mutable bitmap. Draw the camera bitmap and then whatever you like to add.

Yes is the camera preview image.
Thanks for your solution
