Android Question Add Arc to Path

[BPak]

   Dim p As Path
   p.Initialize(0, 0)
  
   Dim jo As JavaObject = p
   Dim x = 100dip, y = 100dip, radius = 100dip As Float
   jo.RunMethod("addCircle", Array As Object(x, y, radius, "CW"))
   cvs.ClipPath(p)

Where can I find references to obtain more info on Adding different Draws to a Path?
Like DrawArc and so on.
The above code comes from Clipping a Cirlce to draw a bitmap on and uses JavaObject to 'addCircle'.

Where are references to 'addCircle' and other types of drawing?

The API is described here: http://developer.android.com/reference/android/graphics/Path.html

Sub Activity_Create(FirstTime As Boolean)
   Dim c As Canvas
   c.Initialize(Activity)
   Dim p As Path
   p.Initialize(100dip, 100dip)
   Dim r As Rect
   r.Initialize(0dip, 0dip, 200dip, 200dip)
   AddArc(p, r, 0, 90)
   p.LineTo(100dip, 100dip)
   c.ClipPath(p)
   c.DrawColor(Colors.Red)
End Sub

Sub AddArc(p As Path, r As Rect, StartAngle As Float, SweepAngle As Float)
   Dim rf As JavaObject
   rf.InitializeNewInstance("android.graphics.RectF", Array (r))
   Dim jo As JavaObject = p
   jo.RunMethod("addArc", Array(rf, StartAngle, SweepAngle))
End Sub

By using the Accelerated Surface library, you don't need to bother with javaObject to call the API and your drawings are done a lot faster (as it benefits from the hardware acceleration).

Thank you Erel.

Informatix, I have tried your library but the HardwareAcceleration does not agree with my computer.

Thank you Erel.

??? What do you mean?

 

[BPak]

When compiling an Example a message is displayed:
Android Manifest:xml 19: error:
No resource identifier found for attribute 'hardwareAccelerated' in package 'android'.

 

[Erel]

Open Android SDK Manager and download a more recent platform then configure the IDE to use it (Tools - Configure Paths).

Thanks Erel - works fine.

Top Library Informatix. Can see many uses for it.
Thank you!
