i am trying to call the MotionEvent.obtain Methode using the reflections library. But so far i am not very successful. Everything i try results in the same error... Here my code from a button-click:
Dim upTime As Long
Dim ev As Object
Dim args(12) As Object

Any help would be great... Thank you, Richard.
Did you see the Multitouch tutorial? Maybe the Gestures library already does what you need.
Anyway you can do it with this code:
Sub Activity_Create(FirstTime As Boolean)
Dim me As Object
me = ObtainMotionEvent(1000, 1000, 1, 100, 100, 500, 500, 0, 100, 100, 0, 0)
Log(me)
End Sub
Sub ObtainMotionEvent(DownTime As Long, EventTime As Long, Action As Int, _
X As Float, Y As Float, Pressure As Float, Size As Float, MetaState As Int, _
XPrecision As Float, YPrecision As Float, DeviceId As Int, EdgeFlags As Int) As Object
Dim r As Reflector
Dim f, i As String
f = "java.lang.float"
i = "java.lang.int"
l = "java.lang.long"
Return r.RunStaticMethod("android.view.MotionEvent", "obtain", _
Array As Object(DownTime, EventTime, Action, X, Y, Pressure, Size, MetaState, _
XPrecision, YPrecision, DeviceId, EdgeFlags), _
Array As String(l, l, i, f, f, f, f, i, f, f, i, i))
End Sub
