Hi, The DeviceSampleAPI in particular the Battery activity is crashing already within the onCreate.

W/ActivityManager: Force finishing activity com.datalogic.examples.devicesampleapi/.DeviceAPITest

It seems that there is an issue around this line: DLBatteryManager deviceBattery = DLBatteryManager.getInstance();

Info:

My general goal is to accomplish to get additional BatteryInfo like CAPACITY_FULL, PRODUCTION_YEAR, SERIAL_NUMBER and so on. Thanks for any help.

Hi Mattias,

thank you for your reporting. Take into account that the version of Memor10 installed on your device could not support the Datalogic SDK v1.20 released on August. Please, could you share us the build number of sw version installed on your Memor10 Android 8 device? I will check which version of Datalogic SDK is support by your Memor10 device.

thank you, MP

Hi,

Thanks for quick reply. I'm sorry I mixed something. I'm using v1.20 within my application, the Datalogic DeviceSample APi is using 1.17.

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.github.datalogic:datalogic-android-sdk:1.17'
}

Thanks upfront.

Thank you Mattias for the clarification. May you share with us the build number of sw version installed on your Memor10 Android 8 device? This is very important to allow us to check and address your issue.

Thanks, MP

Your device supports Datalogic SDK v1.08, as you can check from the Settings. But the features of com.datalogic.battery (reported by your error log) have been introduced by Datalogic SDK v1.13. So, you should update your device with a newer sw version, if you need to interface with new feature of Datalogic SDK.
