I'm having trouble trying to get some custom behavior from the KeyguardManager API, particularly the createConfirmDeviceCredentialIntent() method. According to the docs, it's used to:
Get an intent to prompt the user to confirm credentials (pin, pattern or password) for the current user of the device. The caller is expected to launch this activity using startActivityForResult(Intent, int) and check for RESULT_OK if the user successfully completes the challenge.
From what I can tell, there's no mention of restrictions on how you start this activity, yet setting flags like Intent.FLAG_ACTIVITY_NO_HISTORY seems to make no difference. Am I right in assuming that Google locked down some functionality for security reasons? If not, what am I missing?
