Android Question manager.Enable not work huawei (administrador)

[vercettyDev]

manager.Enable("please enable in order to get access to the secured server.")

I'm using the admin lib
but the .enable function is not sending the intent on huawei phones
If I activate manually it works perfectly (entering the settings)
does anyone know how to solve?

Have you tested it in a different device?

 

[vercettyDev]

I don't have another huawei to test

 

[vercettyDev]

does anyone know how to call an intent that goes to administrator?

 

[vercettyDev]

same problem, does anyone know how to call the intent with java?

I have a Redmi Note 8 Pro

I ran the sample app from here ->https://www.b4x.com/android/forum/threads/device-administrator-library.19208/

Only change was to Update to work against API 30.

Hitting Enable works fine.

However, it then crashes and every time the app is run on

    If manager.Enabled And manager.PasswordSufficient Then

On a sumsung tablet, android 7.1.1, it works as expected.

On a Pixel 2XL running Android 11, it crashes with the same error as above.

I can't say for sure as I don't know a lot about it, but it's probably because Google has reduced device administration capabilities for Android 10 and above.
