Hy,
I have a strange issue with my apk. I implemented the barcode reading, and If I start my application, and after that I step to the home screen, and I waiting when the device step into sleep mode, the device is restarts automatically. If I delete all of EMDK things from my application, then it doesn't restarts.
I don't know if it is important, but in my case this restarting thing appear after 5 min inactivity.
I used this tutorial for the implementation: https://techdocs.zebra.com/emdk-for-android/11-0/tutorial/tutBasicScann…
I created a simple demo app, which is do the same thing as well.

The device is a Zebra MC3300
Android version: 7.1

Hi, I can confirm there is nothing in your code that would be causing the reset so this is unexpected. Do you see anything in logcat before the reset happens?
Thanks for you reply, unfortunately when I plug the device to the computer, the device doesn't produce this behavier, therefore I can't see the logs. This is very annoying issue, but I am sure that my app doesn't couse this error, but I would like to prove this.
Alternatively, you can use RxLogger to capture and record adb logs during failure, then copy these off the device after: https://techdocs.zebra.com/rxlogger/5-4/guide/about/
Thanks, I tried, but when the logger runs, the restart thing doesn't happen. So I hate this device :D
Do you only have the one device? I'm wondering if this is device-specific.
Yes I have just one, but the company has more, to who I develop this application, and they also suffer from this issue.
I would recommend to upgrade your MC3300 unit to Android 8.1.
Thansk, how can I do that? Sorry, I have never used this device, so I can not find the built in software update menu in settings.
There is no such system menu in the settings.
Downloads are available on https://www.zebra.com/us/en/support-downloads/mobile-computers/handheld…
But you will need a valid support contract to download files from these support pages.
Maybe I "Fixed" this problem. I always init the Barcode Listener in Activity OnResume method, and deInit in onPause. Looks like it is work, not the best solution, but at least the device desn't restart herself
