Title: Rk3399 multi users on Android 7 Image [Print This Page] Author: dbe_dev Time: 8/15/2017 19:53 Title: Rk3399 multi users on Android 7 Image Have tried setup a multi user environment for the Android 7 image for the rk3399. I want to make sure there is a locked administrator user and a user that is only allowed to run a few apps.
I can add users and set restrictive rights in the settings app but I cannot activate the lock screen for any of the user to become effective nor limit the apps they access.
Also setting a different wallpaper does not seem to work.
Any advice tricks on what to install or configure for a build ?
Also the battery always indicates 50% which prohibits file system encryption to be initiated. Where can this be changed ?Author: isle Time: 8/17/2017 09:39

This is what I found so far:
The lock screen is apparently bypassed by default for box configurations as used by the firefly AOSP build. App limiting does work for some apps but not for the pre-installed rk apps.
Locally did the following to get the lock screen (re)enabled.

The ro.rk.install_non_market_apps being set to true result in an restricted profile always being allowed to install apk's
Setting a different wallpaper only seems to work through modifing the wallpaper file with adb for now.
Battery level can be adjusted using adb "adb shell dumpsys battery set level 99"
