How to password protect an application in Android -


i want user enter password everytime tries enter application. is, user must enter password everytime app comes foreground background, pressing launcher icon or long-pressing home key

i sort-of achieved first part because launcher intent fired , callback in onrestart of activity.

but long-pressing home key , launching not provide callback onrestart.

also if user launches app pressing notification from, notification bar. how distinguish whether app in background or fore-ground before user clicked notification

in onresume call, set logincounter += 1, in onpause -= 1.

if logincounter == 0 => show login dialog.

in notification bar set intent call activity, correct? add parameter "iscalledbynotificationbar" boolean in there.
