Clarifies what the password modes mean, renaming them to "quality"
and updating their documentation and the implementation to follow.
Also adds a facility to find out if a monkey is running, which I
need for the api demo to avoid letting it wipe the device.
- You can now show a dynamic message to the user when asking to
have your DeviceAdmin added.
- A DeviceAdmin can now provide a warning message that is displayed
before a user disables it.
- Better ordering (and text) of the policy warnings.
- New API to set the maximum failed password attempts before the device
wipes itself.
- We now store the number of failed unlock attempts in persistent
storage.
- New managed dialog APIs that will be used by the settings app.
Also a little bit of cleanup as I was working on this - removed the
long unused MailboxNotAvailableException, fixed a java doc in Messenger.
There is now a description attribute associated with all components,
that can supply user-visible information about what the component does.
We use this to show such information about device admins, and wallpapers
are also updated to be able to show this in addition to the existing
description in their meta-data.
This also defines security control for admins, requiring that they
declare the policies they will touch, and enforcing that they do
so to be able to use various APIs.
This adds new DevicAdmin, DevicePolicyManager, and DeviceAdminInfo classes.
See the java docs for each on documentation on them. Basically: a DeviceAdmin
is what you derive from to administer a device; DevicePolicyManager is what you
use to apply and check your policy requirements and perform other administration
tasks.
