Prior to this change, we didn't have a mechanism to warn the user when they were approaching the wipe data threshold dictated by active DPMs. Here's the new flow: - If a device policy manager is installed and sets the max password attempts, we start warning the user when they are within a grace period of hitting the max (currently hard-wired to 5). - We continue to show a dialog after each continued attempt until the user reaches 0 remaining attempts. - We now show a message when they hit 0 so they know why their device is being reset. The device will reboot and wipe data shortly after this final dialog is shown. Also increased the criteria for a pattern attempt from 3 dots to 4 dots since the user can never set a pattern less than 4 in length. This will greatly reduce the likelihood of a false wipe on the pattern unlock screens without compromising security. Change-Id: I28825ef21dfa2e2b6540e743252c6d50c41e5ad7
