AOSP Oreo - Camera Permission for priv-app App

In a custom android Oreo AOSP, is possible grant camera permission for my app in priv-app folder?

I know that is a dangerous permission and should be granted in runtime, but there is any other option that not require the user interaction if the app is in system/priv-app?

I saw that there is a whitelist in /etc/permissions, https://source.android.com/devices/tech/config/perms-whitelist, but I think that is no for dangerous permissions, like camera.

You can grant dangerous permission for private application in /system/priv-app:

Create the default permission file default-permission-sample.xml. You need to replace package name by your app's package name

<?xml version="1.0" encoding="utf-8"?>
<exceptions>
    <exception package="com.your.camera">
        <permission name="android.permission.CAMERA"/>
    </exception>
</exceptions>

Then config makefile to copy default-permission-sample.xml into /system/etc/default-permissions/ directory.

DONE.

You can grant default runtime permissions to a package by modifying frameworks/base/services/core/java/com/android/server/pm/permission/DefaultPermissionGrantPolicy.java

The relevant method here would be:

private void grantDefaultSystemHandlerPermissions(PackageManagerWrapper pm, int userId)

For example, this is how STORAGE permissions are granted to "com.android.sharedstoragebackup" :

// There is no real "marker" interface to identify the shared storage backup, it is
// hardcoded in BackupManagerService.SHARED_BACKUP_AGENT_PACKAGE.
grantSystemFixedPermissionsToSystemPackage(pm, "com.android.sharedstoragebackup", userId,
                STORAGE_PERMISSIONS);
