Test DPC UI app crashes immediately as soon as it is launched

[1infoteste]

I've been unable to launch Test DPC's policy settings app since last May, it crashes instantly when I try to launch it. Device is Samsung Galaxy A34 5G. OS is Android 14 w/ Samsung's OneUI 6.0. The version I'm running is the one available at Google Play.

I confirm this is an issue on Android 13, OneUI 5.1 too. In my case no crash occurs, but the UI is not reacting at all. The only way to remove the device owner is via the app itself which is not possible right now.

I've tried again after installing the 07/17 update. Still crashes on launch but the error message has changed, now Android suggests me to clear cache or tells me that the app is buggy instead of suggesting me to put it to Deep Sleep.

Tried again after installing the 07/19 update. Issue still persists, same behavior as before.

Can you share some additional information and logs / bugreport about this crashes?

How are you installing TestDPC and setting it up as Device Owner or Profile Owner?

[1infoteste]

I've set it as up as a Device Owner following the instructions on the README. I'm not a dev, just using the app for productivity, so I don't really know how to generate a log ATM.

TestDPC is a test application and should not be used in production.

I'm closing the issue as we can't reproduce it.

Hello, I'm aware of the fact it's an application meant for testing. We use it when we don't want to use a real UEM.

I've just installed the TestDPC app from the Google Play:

• version 9.0.12
• device Google Pixel 7
• OS Android 15 Beta (AP31.240517.031)

I've set the device owner using this adb command:

adb shell dpm set-device-owner "com.afwsamples.testdpc/.DeviceAdminReceiver"

When I start the app the logcat in Android Studio is immediately flooded with new logs the app crashes. When I filtered the logs for com.afwsamples.testdpc I saw a pattern of repeating the same logs over and over again.

The notifications permission is mentioned and indeed, I have not granted the app the notifications permission.

Looks like a stack overflow caused by the permission not being granted, because granting the permission in the Settings -> Apps -> etc. makes the app working again :)

Can you please open a different issue?

Also, please review your reproduction steps. Installing TestDPC from Play requires setting up an account on the device and that block setting TestDPC as device owner:

$ adb shell dpm set-device-owner com.afwsamples.testdpc/.DeviceAdminReceiver

Exception occurred while executing 'set-device-owner':
java.lang.IllegalStateException: Not allowed to set the device owner because there are already some accounts on the device.
