Hi,
Again similar question about capturing screen. Actually i want to capture entire panel to bitmap and then save it to file, but it doesnt work. I think tabhost causes conflict, i dont know. But all code examples captures entire screen from absoulute 0,0 top left position. And i am tired to work with rectangles.
Now i am trying another solution. Capturing entire screen and crop it. There are two crop points. From top about 40 dips, and from bottom, about 50 dips. I solved cropping bottom with code below.
Underlined bold line crops 50 dips from bottom. But i dont know how to crop top 40 dips. (What is 40 dips at top. Its tabhost header. I want to crop it. )
Any suggestion for newbie ?

B4X:
Dim Obj1, Obj2 As Reflector
Dim bmp As Bitmap
Dim c As Canvas
Dim now, i As Long
Dim dt As String
DateTime.DateFormat = "yyMMddHHmmss"
now = DateTime.now
dt = DateTime.Date(now)
Obj1.Target = Obj1.GetActivityBA
Obj1.Target = Obj1.GetField("vg")
bmp.InitializeMutable(Activity.Width, Activity.Height-50dip)
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.DirDefaultExternal, dt & ".png", False)
bmp.WriteToStream(Out, 100, "PNG")
Out.CloseUnderlined bold line crops 50 dips from bottom. But i dont know how to crop top 40 dips. (What is 40 dips at top. Its tabhost header. I want to crop it. )
