Now I got it. Then you'll have to be more specific: on my phone there are password lock, swipe pattern lock, face lock, God knows what else. Which one do you need? – David Jashi Jun 04 '13 at 06:01

This may be made intentionally inaccessible... What do you need this for? Maybe there is some other way to achieve your goal? – David Jashi Jun 04 '13 at 06:07

Device administrator doesn't allow you to check whether device has lock screen password (or pattern ...) directly.
However you can do it indirectly.
- Retrieve password quality level from device admin (original value)
- Set password quality to device admin to minimum level (i.e. PASSWORD_QUALITY_SOMETHING)
- Ask device admin whether is password quality sufficient (if true = user has password)
- Restore original password quality level (value from step 1)
DevicePolicyManager allows you to set/get required password quality level and check whether is password sufficient.
Your device admin will need to use limit-pasword policy:
<device-admin xmlns:android="http://schemas.android.com/apk/res/android">
<uses-policies>
<limit-password />
</uses-policies>
</device-admin>
And you should definetely read this Device Administrator Guide.
