Android Question Adding Page Turn view to the second Activity

[somed3v3loper]

Hello

I asked a few questions on Page Turn View thread but got no answer so I decided to start a thread here.

The view is working great when adding it to main activity but if added to another activity it closes the application with "Unfortunately , app closed ..." message and shows

maininitializeProcessGlobals (java line: 371)
java.lang.RuntimeException: java.lang.NullPointerException

on B4A IDE Logs tab

If I change the starting activity with this method

SetActivityAttribute(Main, android:name, ".activity2")
SetActivityAttribute(Activity2, android:name, ".main")

The application works as expected.
Now I do not whats wrong , Did I miss something or is it a bug?
Is there any thing I can do?
Thanks in advance

Thanks but I tried that and then undone the changes because it did not fix the problem
And I believe those attributes are added by B4A

I just ran Klaus code it worked fine.. the fist page has only a button and when I clicked on it, the second page (activity)
with the book was shown.

There are two things I don't understand:
Why do you want to change the starting activity in the code ?
Why can't you post a small project showing the problem.
Without seeing in a small project what you have done and how it's almost impossible to help.

I am sorry for late reply .
Changing starting activity was just to check if pageturnview can only be added to the first activity.

And here is a small project that has the issue
