Android Question Issue in running USBSerial2.3 example

[mandargholap]

I have downloaded the USBSerial 2.3 zip and open the project.

When I am trying to run the program, it is showing unknown type :UsebSerial. Are you missing a library reference.

IN my Project i have set the path to the folder where I have kep both USB_SERIAL.jar and usb-serial-for-android-v010.jar file. The AsyncStreams variable is getting reference but not the UsbSerial.

PL.find attached the screenshot.

Thanks

Have you checked UsbSerial in the libraries tab?

You should go to the libraries tab in the right side of the IDE and check UsbSerial. It is explained in the Beginner's guide: http://www.b4x.com/android/documentation.html

Thanks Erel. I got it.


I have small query. I have compiled the UsbSerial2.3 program. But when I am connecting my Samsung mobile to PC, I am getting No USB device connected error?

Pl suggest.

Are you trying to use UsbSerial with a device connected to a PC? It will not work.

If USB debugging is enabled and a proper driver is installed then you can use ADB to create a TCP/IP connection.

Hi Erel:
I am triyng to compile the USB-Serial example, and every time I do the compiler show me theses lines:
------------------------------------------------------------------------------------------------------------------
Convert byte code - optimized dex. Error
A referenced library is missing: usb-serial-for-android-v010
-----------------------------------------------------------------------------------------------------------------
Then the compile process freeze for long time.

What is wrong?

Thanks in advance.
