Android Question Out of Memory Error

[RVP]

Continuing to work on my project, and I have discovered that if I go back and forth between my main activity and a sub activity a few time, I get a Memory Error. I am going back to the main activity by using the devices Back Button, and doing

Sub Activity_Pause (UserClosed As Boolean)
 
If currentrow>-1 Then UpdateCurrentSchedule ' save schedule in case of changes
 
If UserClosed Then
    Activity.Finish
End If
End Sub

The error is

** Activity (main) Pause, UserClosed = false **
** Activity (schedule) Create, isFirst = false **
java.lang.OutOfMemoryError

I have attached the project in case anyone wants to take a look at it. It takes around 4 times going into, and out of the sub activity to cause the error on my device (Samsung Galaxy Tab 3 with 32gb) I assume it may take more or less on another device.

If someone does look at this, and finds the issue, please let me know how you did it so I understand what to do to track these kind of things down.

Thanks

The code here is very problematic (clsWheel.Initialize)

Do Until pnlMainWidth <= 100%x AND pnlMainHeight <= 100%y
     cvsParent.Initialize(Parent)

It creates multiple canvases. The first thing to do is to move cvsParent.Initialize out of this loop.

Try the updated ClsWheel Class Version 1.7.
The probelm reported by Erel has been amended.

Thanks, both, that fixed it, as well as made the app a whole lot faster!
