Android Question USB-Serial 2.3 with b4a 3.82 problem ?

[tiger]

Hi,
last week I bought b4a 3.82. My old projects with USB-Serial do not work on severel devices.
After init the USB I get following error on the devices ( all with Android > v.4.1x)
: An error has occurred in sub:
java.lang.RuntimeException : Cannot parse: 0 as boolean

and sometimes:
An error has occurred in sub:
java.lang.RuntimeException : Cannot parse: 1 as boolean

What can I do ?

It is possible to get an old Version of usbserial lib ?
Thanks for help , Reimer

Run your app in debug mode and see which line causes this error.

Hi Erel,
thanks for the fast answer.
the debugger stops at line 60 :
If usb.Open(115200) Then
Log("Connected successfully!")

device said: Program paused on line:60
I didnt set any breakpoints
meanwhile made update from SDK
but have the same problem

Thanks again Reimer

Have you checked the logs for any errors?

yeap the log said the same at line 60
An error has occurred in sub:
java.lang.RuntimeException : Cannot parse: 0 as boolean
same with your usb-serial example

See the description of UsbSerial.Open: http://www.b4x.com/android/forum/pages/results/?query=usbserial.open&page=1&prefix=0

It returns an int which can be one of the following values: USB_NONE, USB_DEVICE or USB_ACCESSORY.

Hi Erel,
thanks again. I made a variable to check the USB_OPEN and now it works fine as before
