Hi, I am new to android development and got a client requirement (Specifically related to android phone having version 5.0 or higher) where a user wants to switch his/her "User Account" from user mode to guest mode programatically without rooting the device or without using the NFC method. I have read few blogs related to this, which suggests the application to be installed normally on the device, then by using *"adb shell dpm set-device-owner"* command we can set the application as device owner. Then comes this method "switchUser(ComponentName <https://developer.android.com/reference/android/content/ComponentName.html> admin, UserHandle <https://developer.android.com/reference/android/os/UserHandle.html> userHandle)" ,in program the functionality of the method is specified "Called by a device owner to switch the specified user to the foreground." called from my application to switch the account. But while calling this method in my app and at the time of giving the administrative privileges to the app in command prompt I get an error "Error: Unknown admin: ComponentInfo{ the package name/ the classname including package name }" . My query, whether the error is related to the method, or with the commands or is it related to the manifest file. It would be helpful if anyone gives some suggestion related to this.
