Best MDM Solution For Android Application
-
Anyone have any experience with Mobile Device Management solutions? I’ve been vetting one vendor but my application freezes every time I hit the back button while my application is in Kiosk Mode. I thought the issue was specific to my application but I built a simple application from the ground up and sure enough I ran into the same issue.
What’s the best MDM solution for an Android build in your opinion? Thank you in advance!

@keiron-stoddart you mean every Back Button freezes or only the-last-one - normaly quitting the app ?

@ekkescorner thank you for the response! Every back button freezes. For what it's worth, here is the Logcat output for the simple application.

have some customers using MDM systems for Android and iOS, some also using Kiosk Mode
some customers are using BlackBerry UEM as MDM
https://www.blackberry.com/de/de/products/endpoint-management/blackberry-uem
one customer (running 7 different apps) is using another MDM system not so expensive as BlackBerry UEM:
Hexnode https://www.hexnode.com/de/mobile-device-management/
BTW: which MDM solution are you using ? -
As an IT administrator, I value the granular control that Apptec360 MDM offers. From setting restrictions on device functionalities to configuring security settings, I have full control over device management. The reporting and analytics dashboard provides valuable insights that help me track device usage and compliance.
