Android Question Disable Context Menu

[rogersantosferreira]

Hi everyone...

How can I disable the context menu on Android's B4A app?
I can't find anything like that on forum. My app is crashing ("app failed unexpected") when I press the menu button on an old device and so when I do a longTouch on context button on newer devices.

Thanks in advance.

Check the logs to see the full error message.

There will be no menu if you won't add menu items.

When I try to access a context menu (on old and new devices) I get this error by log console:

I just remove this code below and everything is fine now!

'trying to remove the app from memory
Sub Activity_KeyPress (KeyCode As Int)
If KeyCode = KeyCodes.KEYCODE_BACK Then
ExitApplication
End If
End Sub

Why this happens?
Thanks one more time, Erel.

Should the sub Activity_KeyPress return a Boolean value to indicate if it has handled the key press?

A sub that returns no value does in fact, internally, return a String.
So android expects a Boolean but gets a String - hence the class cast exception.

Exactly warwound! You're completely right!
Thanks for the support.
