Application Policy
Troubleshooting for Application policy
"Application policy with this name already exists in this enterprise"
Choose a different Description Name.
"Network, Charging and DeviceIdle constraints not allowed for this install type"
Installation constraints only work with ForceInstalled or PreInstalled. Clear the constraint fields or change the Install Type.
"Install priority can only be set for ForceInstalled or PreInstalled apps."
Clear Install Priority or change the Install Type.
"Kiosk role type requires install type to be RequiredForSetup or Custom."
Change the Install Type, or remove the Kiosk role.
"Only Kiosk role type can have UserControlSettings set to UserControlAllowed."
For CompanionApp and SystemHealthMonitoring apps, set User Control Settings to something other than UserControlAllowed.
"Play related fields cannot be set for Custom install type"
Clear Minimum Version Code, Install Priority, Auto Update Mode, Accessible Track Ids and the installation constraints — they do not apply to custom apps.
"Signing key certificate fingerprint required for Custom install type" or "APK version code must be set for Custom install type."
The custom app's fingerprint and version are normally filled in automatically when you select the app. Re-select the Application and check the Signin Key Fingerprint and APK Version Code fields.
"Custom install type can only be used with custom apps" or "Install Type must be Custom for custom APKs"
Custom works only for uploaded APKs, and uploaded APKs work only with Custom. Check which app you selected.
"Role type not allowed for Custom install type"
A custom app can hold the Kiosk role only. Remove the other roles.
"Cannot delete application policy because it is used in configuration"
Remove the policy from every device group that uses it, then delete it again.
The app never installs
Check the installation constraints (the device may be waiting for Wi-Fi, charging or idle time), the device's Android version against Min Android, and for custom apps that the device is fully managed.
