2.0 Beta: It's not possible to store a reference to the Activity in a user class

[corwin42]

I tried to store a reference to the activity in a user class. It is not possible to Dim an Activity object.

Sub Class_Globals
   Private mActivity as Activity
End Sub

Sub Initialize(Activity as Activity)
   mActivity = Activity
End Sub

gives follwing error:

Compiling generated Java code.          Error
B4A line: 10
Private mActivity As Activity
javac 1.6.0_23

_mactivity = new anywheresoftware.b4a.objects.ActivityWrapper();

So if you need access to the activity in a user class sub then you have to pass it always to the sub. I would love to do it only in the Initialize() sub.

I don't know if this is really a bug because Activities are very special objects but is there any possibility to directly access the activity from a user class?

I'm new in classes but you can't do this I think

You can't name it Activity as Activity

Sub Initialize(Activity as Activity)
   mActivity = Activity
End Sub

Am I right???

No. It will not work as you currently cannot declare a variable of type Activity.

This will be possible in the next beta update.
