After achieving device ownership, I am trying to implement a method to instruct the device to lock any given app into kiosk mode (or screen pinning mode). Since I have device ownership, the user is not asked for the permission to do so.
From the developer website, brief description tells me that it is possible to do what I am trying:
http://developer.android.com/about/versions/android-5.0.html#ScreenPinning
Programmatically: To activate screen pinning programmatically, call startLockTask() from your app. If the requesting app is not a device owner, the user is prompted for confirmation. A device owner app can call the setLockTaskPackages() method to enable apps to be pinnable without the user confirmation step.
This indicates that as a device owner app, I can pin other apps without user confirmation... but I have no idea how to.
I have been able to put my own app into pinned mode.
Any help would be appreciated.
The setLockTaskPackages()
is used the specify which applications (through their package names) will be able to programmatically be pinned without user confirmation.
The setLockTaskPackages()
is called from your device owner app (most probably in your DeviceAdminReceiver
's onEnabled()
method).
So, in you owner device app, you'll have something like :
mDPM.setLockTaskPackages("com.foo.myapp");
and then, in your "com.foo.myapp" application, you will be autorized to call :
startLockTask();
Your application will immediately enter the Pinning mode, without any user confirmation.
If you don't first register
your application with setLockTaskPackages
, the application will be pinned but the user will have to confirm first.
Also notice that when an app is registered
with setLockTaskPackages()
, it has some different behaviours than the manual pin:
stopLockTask()
;
