Hello, I'm getting com.common.apiutil.NoClassObjectsException error when I invoke any method in the ThermalPrinter Class. How can we fix this?. I am trying to integrate the  `DemoSDK20241212_V2.28`  SDK into my application - M1K Android POS device

We think you are using the wrong code which you should use "UsbThermalPrinter" instead of "ThermalPrinter". And please check the MainActivity.java source code. M1K opens the UsbPrinterActivity page instead of the PrinterActivity page.
