I’m trying to get the FIRMWARE_VERSION from BatteryManager no a Joya A6, but when I try to get it I get the following error:
“java.lang.NoSuchFieldError: No field FIRMWARE_VERSION of type Lcom/datalogic/device/battery/BatteryInfo; in class Lcom/datalogic/device/battery/BatteryInfo; or its superclasses (declaration of ‘com.datalogic.device.battery.BatteryInfo’ appears in /system/framework/framework.jar:classes2.dex)"
I saw that this was added in revision 40 on the SDK but I cannot find a way to find out which revision is running on the device to be able to check if the feature is available, is there a way of knowing this?
