Device Administrator - How do I set lock screen?

Let me show what I mean.
https://play.google.com/store/apps/details?id=com.jusckeux.nolockscreen
This app is the best thing since sliced bread.
I only miss one tiny bit.
I would like to have a SWIPE lock option as well.
Of course I would love to extend this particular app, but I can't reach the author. No website, Google didn't give me anything, etc.
So.
- How do I write the same app again?
Like.. which API do I need for modifying the lock screen in such way?
- Is it possible to have a swipe set-up with the API, or just the current NONE / lock states?
Because if it's not possible, there is no point in messing around.
.....
I would only modify the widget if it would be possible, by adding a "YELLOW" colored state which would mean Swipe. That's it.
Because I like having no unlock, but I already pressed button accidentally because of it.

Looks like the API supporting this is quite dumb.
http://developer.android.com/refere...ger.html#resetPassword(java.lang.String, int)
It supports only settings a password, and removing it (by having NO password). But having Swipe is too much, can't be done.

Using Nexus Imprint to LOCK the 6P?

Hello! So this is the first phone I've used with a fingerprint reader. I love how quickly it unlocks the phone. However, I keep finding myself swiping my finger to try and lock the device after I am done using it. It seems like a very simple and intuitive feature that Google should have built in. Anyone have any idea if something like this could be hacked together? I think a lot of people would love the convenience of this!!!
If screen off - fingerprint to unlock
If screen on - fingerprint to lock

This should absolutely not have been built in. You'd constantly accidentally lock the phone; my finger hits the scanner a lot when I move the phone around.
I'd be a nice ROM feature for those who want it though...

Yeah that does sound rather interesting would love to see that implemented into a mod

I guess I could see why it wouldn't be on as default...but a switch to activate it would be cool! You could easily learn not to touch the reader to trigger a lock I'd suspect.
I think it'd be a cool ROM feature and/or Mod though for sure. Pretend like the feature works next time you have your phone unlocked and you want to lock it and you'll see why I think it'd be so convenient.

It'd have to be a bit more deliberate gesture, like double tap the scanner. Now that would be nice.

Tap to wake or unlock via fingerprint possible?

Got it a couple of hours ago and I''m wondering if there's any way round having to press the home button to unlock the phone, like being able to just rest my finger on the pad to wake it and unlock.

Any idea how to enable double tap to wake up the S7 edge? Just a new user coming from the xperia Z2.

I'd also love to know hopefully it's possible.

Nearest thing I've found so far is to enable edges then when screen is off, swipe up and down to show the edge content at which point you can unlock via fingerprint reader.

Not really, only the other way round, press the home button and leave the finger on it and it will unlock straight away.

Not possible unfortunately. The method Tectas explained above, is the quickest way.

Found this way to, but would prefer an easier one.

Well I have tried a few tap to wake apps and they all fail. This is making me think that the always on display is actually an app in its own right meaning the tap to wake apps don't activate. Any thoughts my learned colleagues?

Gotta push the button. I understand you want to just rest your finger and let it unlock (like nexus 6P) but is it really that hard to put little bit of pressure to actually push the button and just leave your finger there like you would have with a 6P? Only step you're doing is moving your finger 1/40 of an inch to actuate the button lol.

Partial success! Following this guide for the S6 edge I can have tap to wake working http://forum.xda-developers.com/galaxy-s6-edge/general/tap-to-wake-samsung-device-t3141850
The snag is, and here's the new challenge, to have either AOD or edge clock working whilst it's asleep.
@razorseal : it's not a biggie, I am just trying to recreate the functionality of Windows phones as it was a beautiful workflow that I'd like to keep of glance screen and DT2W/DT2S.
So I'm thinking it's an app like Knockr I need but one which somehow allows AOD to work. Any suggestions welcome - I'm not averse to rooting to achieve this.

Getting closer still. So I uninstalled all that stuff from the link above and put this app on: https://play.google.com/store/apps/details?id=com.orthur.always_on_display&hl=en
It has an AOD display which if you put your finger on the pad it reads the print and unlocks. It does have a double tap to wake as well which can be used to open the lock screen and then do the fingerprint.
So now I just need a double tap to sleep app then if the battery drain isn't too crazy, the mission is complete.
Anyone know a good double tap to sleep app that isn't a floating widget? Something like on CM13 whereby you double tap the status bar and it goes to sleep would be good.

You could always enable the 'Easy screen turn on' feature, which can be found by going to 'Accessibility' and then 'Dexterity and Interaction'....
I believe this was previously known as 'Air View'.
I hope this helps.

This will probably drain your battery too much. Many of these (root-less) apps keep the AMOLED screen on but with a black rectangle displayed so it looks like it's off. But don't fall into the "AMOLED black does not consume power" lie. There is an entire system powering the screen that consumes power.

Yep this is the easiest solution folks. It's what I use. Just a simple wave or swipe finger over the proximity sensor, device wakes up. There is also a setting elsewhere that stops the phone from waking up if its in your pocket or so, so good idea to use that too.

Quite a nice solution. I wonder if it has any impact on battery, since the proximity sensor is probably always-on ?
I still hate Samsung for not implementing double tap to wake. I mean, they copy everything from Apple, but they can't copy a really useful feature like this from LG (or whoever had it first without battery drain) ?

I've had this enabled for a couple of days now and my battery life is fine, yesterday I got the best screen on time which I've ever had on a phone, 7hr 20 min....so far I don't think it's having an impact.

Answer to your question is Nova Launcher Pro. You can use the double tap gesture to lock the screen, no widgets required. Let me know if you have any confusion with that. The only downside with that is when I wake the phone back up, it says and I quote "Enter PIN instead of using fingerprint recognition because of security policy". It's quite a big deal for me, having to type in the PIN instead of just resting my finger on the home button. Still searching an answer for that. If anyone has found a workaround/solution, please let me know.
PS: Sorry, I had to cut the playstore link from your original message, XDA forums won't let me post with a link in it.
---------- Post added at 11:02 PM ---------- Previous post was at 10:35 PM ----------
So, I researched a bit and found a workaround. I am not allowed to post links here, so, find an app called 'Screen Lock Pro' from the Play Store. Its by a developer called Prahallad and costs $2.37. Then activate it as a device administrator, go to setting and enable 'Smart Lock and Nexus Imprint'. Then go back to your Nova Launcher settings, into 'Gestures & Inputs'. Select 'Double Tap' under gestures and select the shortcuts tab on the top. From there, select the 'Screen Lock Pro (Shortcut)' and you're done. There are a ton of other features in the app and I am still trying them all out one by one.

Hide the iris scanner camera when unlocking?

Hi everyone, I was wondering if it were possible to hide seeing my face when using the iris scanner, I think it would look more neat.
I know you can activate the iris scanner as soon as you wake up the phone but I set the home button to automatically unlock (since I use smart lock and that makes it very convenient) so when I press the home button it'll instantly go to the unlock screen where the front cam is activated.
OK I guess I could use the power button instead but I was wondering if there's a way with the home button. Thanks!

Mine is intermittent as to when it does show the camera view. Most of the time it will just come up with a line of text saying look here for iris scanning and I'm never quite sure where I'm supposed to actually be looking.

You should be watching towards the top of the screen near the grid, you should do this even before turning the screen on and it's faster and more accurate

If you look at the red light left hand corner it's unlocks instantly

Yeah its not too bad, i wear glasses so is a bit of a pain sometimes it works through them most of time it doesn't. I might try and get used to doing that "guess where the fingerprint scanner is without putting your finger all over the camera lense" manoeuvre.
I meant why does it *sometimes* come up with the camera viewfinder - does yours *always* come up with the camera viewfinder?

It shows the camera when the unlock isn't instant, or this is what I noticed, just wanted to hide that for a sleeker look

Not an answer but an option. You can go into Settings>Lock screen and security>Iris Scanner>Preview screen mask
There's some goofy masks but maybe there is one that might preset a "sleeker" look for you.

Yep I know about that, that makes everything even worse imo Ahah the main problem to the "sleeker look" is that the camera is super low res, I don't know just feel it's useless but u guess there's no way to get rid of it

I got exactly same question !
That things is pure ugly in term of design and aesthetic, LoL
Hopefully someone can found a way to permanently hide that visual

To unlock your S8 or S8+ with your iris without seeing the camera preview go to:
Settings => Lock screen and security => Iris Scanner
... and turn on the very last option called "Iris unlock when screen turns on".

Thank you,
But we already know and use that option indeed.
But sometimes, we want to jnlock the phone on the table, when its not facing our face, thus we slide up the lock screen,
And then, bam, those ugly visual appear above the PIN number pad. LoL
Sure it has nothing wrong with the function. We just simply hate how it "broke" our beautiful lockscreen layout

You can trigger the iris scanner again by clicking the text on the top center instead of swiping, this will not show the guidance visual.

I found the best way to mitigate this is to do two things.
1. Enable the toggle for "iris unlock when screen turns on" under lockscreen>iris scanner
2. Disable the toggle for "Unlock with home button" under setting>display>navigation bar
It's still not perfect but I'm at 90% success rate and it's far faster than fingerprint debacle. I figure when you press the home screen without option 2, phone triggers instant to unlock. With it unchecked it pauses so you can look at notifications.
Should default this way imo.

By golly you are right!

I know this is an old thread but I just would like to thank you for this tip! I always look at the line of text to unlock my phone and it sometimes doesn't do the trick. But looking at the red dot hasn't failed me yet!!! And it's almost instantaneous! Thanks for this tip.

Lockscreen won't stay in landscape for pattern.

Hey! I just rooted my Oneplus6T, installed Nova Launcher and a screen rotation controller app, but I still can't keep the lockscreen in Landscape mode.
I double tap to wake the phone, it comes up landscape, I swipe up, but then the screen always rotates to portrait for the pattern (or the PIN, I tried that as well).
I've already altered the build.prop file, but it still hops to portrait every time. Is there anything I can do to fix it?
I tried a lockscreen replacement called "Hi Locker", and while it worked, you could just get right through it to the home page and do stuff, so it's not secure at all.
Thanks!
I just tried Substratum "Subtweaks" and it doesn't work either! Help!

So everyone else's phone stays in landscape when they enter their pattern to unlock?
Seriously, it would help if I knew this was JUST my problem. Might help me figure it out. Thanks!

Well, I'm glad to have joined such a robust, supportive community. :\

Pretty sure the lockscreen is only portrait. Why anyone would want it in landscape is beyond me, probably why it's not there at all.

Every time I want to unlock my phone in the car, I have to do it sideways. I used a Note 3 that gave me a Landscape Mode Lockscreen for years, so it's certainly possible. I much prefer it, and I would like it on the Oneplus 6T, please.
And thank you, Bladestonez, for responding to my question, even if it was just to imply that it was ridiculous. Never settle! :\

You can always flash an aosp rom. I'm pretty sure aosp has lock screen rotation, you will however you'll loose the fingerprint scanner but it appears you don't use that anyway so might be a good option. Could also suggest lockscreen rotation as a feature for future builds of oos.

Hey! Thank you. I root to block ads and back stuff up, not to start installing custom roms, so I may just wait and see if they can add it officially. I did a little dance recently when I was able to install the latest OTA with Magisk without losing root. That's about as far as I want to push stuff like that.
I DID try the build.prop code, and while it does make the "swipe up" screen Landscape, when I do swipe up, the "pattern dots" screen rotates to Portrait.
https://www.youtube.com/watch?v=jqMiWAlAaUI
It's not a deal-breaker, it's just stupid. As well as my Note 3, every tablet I've ever had has given me a Landscape Lockscreen, so it can't be THAT hard. They probably just decided no one wanted it and didn't include it (or inadvertently disabled it), I guess.
If anyone has any other ideas, I'm all ears. Otherwise, I've already been in touch with Oneplus and I think they put it on the wishlist for me. Gonna start holding my breath... NOW.

Yes, I know my case is the opposite, but you can use the same app.
My case:
Today I have noticed that on lockscreen the screen is rotating what did not happen before. I have tried several Rotating apps but none of them could block rotating of the screen while on lockscreen.
Lastly I managed to force it to portrait mode with https://play.google.com/store/apps/details?id=com.pranavpandey.rotation
In the Settings - Conditions - Lock Orientation - it has to be set to Autorotation OFF then it works. When I set it to Portrait it doesn't.
So in your case you could try setting it to Force Rotation or Landscape.
