I have a "device owner" Android app which silently installs APK using PackageInstaller (see the code, for example, here).

This code works perfectly on all Android 7+ devices except Xiaomi Redmi 7A (running MIUI 11). The installation fails, here's the related logcat output:

01-16 00:43:21.639  1488  1658 E PackageInstaller: Commit of session 417086238 failed: Permission Denied

Package ID of the installer (device owner) is com.hmdm.launcher. Package ID of the app being installed is com.hmdm.sendphoto.

I tried to add the "Install unknown apps" permission but this didn't help.

Looks like the app must request MIUI OS for some special (undocumented) permissions?

The device owner rights were granted to the application by QR code based enrollment.

Also with MIUI 10.3 some apps are refused to install/update. For instance, I cannot install a Threema update the usual way (and just get a silly error 'not installed'). logcat shows that com.miui.global.packageinstaller.action.verifypackage called by com.android.server.pm.PackageManagerServiceInjector fails:

What worked for me was to move the apk file to /data/local/tmp/ and then call as root

pm install -r file.apk
