DeviceAdmin policies PASSWORD_QUALITY_NUMERIC not working

I am working on DeviceAdmin policies implementation, followed below link for implementation http://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#PASSWORD_QUALITY_NUMERIC , In that if we selected PASSWORD_QUALITY_NUMERIC password Quality from spinner, while setting password, it should ask for at least one digit but not showing any information to 开发者_如何学JAVAinput digit, simply accepting ALPHABETIC, not asking for at least 1 number.I hope this is not expected behaviour,may be i am wrong Please let me know Am i misunderstand PASSWORD_QUALITY_NUMERIC?.If i selected PASSWORD_QUALITY_ALPHABETIC, i tried to give only digits, this time asking for at least 1 letter. Thanks in advance :D

This is working as intended. From my comment on the bug: "The request for password quality is a request for the quality to be at least as good as requested. A password with letters is better than a password with numbers, so it is fine for the user to enter a purely alphabetic password in this case."
