Android Question Issue in running USBSerial2.3 example

Have you checked UsbSerial in the libraries tab?

Thanks for the prompt reply.

Pl. find attached screenshot of the jar file location and the path setting.

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.

Marcelo
