[REQ] Lock Screen App

The power button on my N1 has been giving me fits, and given the number of people I've read about with "dead" power buttons, I think mine is going out so I'm trying to preserve it as long as possible.
I enabled trackball wake (using CM6) which takes care of 1/2 the equation, but I need a good lockscreen app (just something to make the phone go to sleep). I found one in the market called Lock Screen Enabler, but it's not a "true" lockscreen app and it's very buggy, causing all sorts of problems for me.
I've been a web developer for 8 years and recently got into Android development (which I hope to be doing full-time soon), so I thought I'd just code a quick app for personal use in 5 minutes.
The problem, however, is that the DEVICE_POWER permission is needed in order to call goToSleep() and from what I've read so far from other online posts, this permission is only granted to native system applications.
Since my phone is rooted, I even tried granting my application SU privileges, but that doesnt seem to work either.
So, my question boils down to how do I grant my application DEVICE_POWER permission? I figure if anyone out there knows the answer, it's going to be someone on XDA as this place is full of geniuses. Thanks in advance!!
UPDATE: I've attached the finished app. Made this for personal use but if anyone wants to use it they are welcome to. My only gripe about it right now is the "screen flicker" that happens when you launch it because it's trying to launch an app that immediately locks the screen and finishes itself. If I can figure out how to get the app to launch in a smaller window maybe I can minimize the size to reduce the screen flicker. But for now, this works and I can set it to launch when I click the clock on Fancy Widget, so I'm happy. Thanks again to everyone who offered answers to my questions. Just another reason why I love the Android development community!!

Search for Lock screen widget. I have the same problem and I use it. It immediately locks your phone once pressed

Awesome, thx! Still would like to know how they got that prompt to show that basically made the application an Administrator app. Seems like the missing piece I need to complete my own

It seems that you'll need to add the application as a device administrator. There seems to be some decent information half way down this page under Device policy manager: Link.
I'd be interested in using this application as I can't change the icon of my previously mentioned widget.
Edit: More information here as well: Link.

I will probably still go ahead and create one. I like how with FancyWidget you can set it so clicking the clock will launch an app. Unfortunately it doesn't work with widgets, so I need an extra icon on my home screen just to lock it. If you have an icon you'd like me to use, feel free to share and I'll put it in
And thx for the info!!

I would be happy with any icon to be honest, I just don't like the lock screen widget one Good luck bud

Alright, I got it working, but there's one problem. It can't be uninstalled because it's currently a device admin. Same goes for that Lock Screen Widget I installed earlier.
Looking into a way to be able to uninstall, if one even exists....

You disabled: device administrator ?

Try using "root explorer" to find the files and just delete them.

You need to go to Security & Location - Device Administrators and disable both there.

Good call. Thx. However, I also came up with a work-around for ppl who are just as lazy as myself. There are 2 icons in the launcher. The first will lock the screen (once you enable the app as a device admin). The second will disable the app as a device admin, allowing you to uninstall at your will.
I really intended for this app to be for personal use, but if anyone wants it I'll put it up here for you to download. If you'd rather I remove the second launcher icon and just let you to disable it through Security settings, I will also do this (as really, I don't plan on uninstalling any time soon so this is fine for myself).
Thanks to everyone who helped out!!!

OK - I'll update and upload when I get into work

Application is in the OP. Have at it

Great, works perfect on MIUI 0.9.30

Does the job perfectly! I especially like how it runs as an app so I can change the icon

You're a lifesaver, or should I say power button saver
Thanks so much.
I tried to develop something similar before but got stuck. Saved me some time!

Thanks for creating such useful app for my N1. My power bt is fine, but I would like to preserve it to powering up/down the phone.
BTW, I also downloaded Lock Screen Widget to test it out. Is it possible that you can make your app to shut off the screen smoother, like LSW? I like it you set it up as an app, which is super useful for me set up as a gesture swipe on my LauncherPro dock icons.
Thanks again and keep up your good work!

Thanks again, your app is really great. But could you add a option to map it to the search button (long press) please?
Thank you!

Fingerprint per app

Is it possible to use fingerprint per app basis I know this was possible on galaxy s5 via a third party. I see an option in ascend which doesn't make sense to me in finger Id access app lock.
If someone can elaborate on the third option in fingerprint Id.

Adam,
1st one is for the lock screen
2nd is for the safe. You can find it in the files app.
3rd is for app lock. Go to phone manager and swipe right. Thats where you can lock apps and unlock them with the finger print.
Hope i helped.

How to change lock screen clock?

might be a noob question, but is there a way to put a different widget/clock on my lock screen or am i stuck with the boring stock one? I'm talking about when my phone is locked, not my desktop.

If you download Samsung's app, Good Lock, in the Galaxy Apps store, you'll have the option to change the lockscreen clock widget. However, with the app, a lot of other things change as well.

I think you're going to have to use a custom lock screen app from the Play Store. There are a bunch on there but most of them don't support the fingerprint scanner, you'll have to use a digit or pattern unlock code.

Lock Screen Wallpaper

Anyone figure this one out yet? I have been scratching my head trying to be able to change mine. I followed some guys instructions on Reddit, but that didn't work for me. Wondering if anyone else had figured it out.

at least on the pb2-650y

Can you post a screenshot? I'm just curious at this point. There's also access to some settings from the lock screen.
Edit: disregard, it just goes to system settings or Nagar settings.

Here's how to change it:
Long press on an empty area of the home screen
At the bottom, choose "Lockscreen Wallpaper"
Make your selection
Hit "Set For LockScreen Wallpaper"

Do you have the phone? If so your phone is different than mine. I don't have a lockscreen wallpaper option.

nope.
The lockscreen wallpaper is kind of annoying, but the persistent "This device is HD capable" notification is driving me out of my mind.

He's using the stock launcher. If you switch back to that, you can change the lock screen wallpaper with a long press on the homescreen.

Unfortunately, I didn't (well, at least not for what you're seeing in that screenshot). If you visit plus.google.com in Chrome, it offers to put a link to the site on your home screen. So, that icon just opens the web version of Google+. I did install Google+ earlier today, but because I had to sign it myself to remove the conflicting permissions (it conflicts with the improperly built Gallery app), Google's servers rejected the client. IMO, the only chances we have of getting a working Google+ installed are 1) if the phone is rooted, then we should be able to replace the Gallery app with a non-broken one, or 2) Lenovo needs to fix it. Option 2 might happen by accident if they ever decide to release Android 7.

Looks like you can only change the lock screen wallpaper to a static picture, no live wallpapers unfortunately. On other phones you can.
Also, I can install and use Google+ just fine it seems, perhaps because I installed their latest December update.

My stock launcher somehow become corrupted, every second, I get "Unfortuantely Launcher has stopped working". It was a ***** to get to the Google Play store between saying, "ok" and having the message pop again in 1 second. So I was able to get into Play store and install another Launcher that is near the original Launcher_3. However, it does not have that LockScreen Walpaper mode.
I don't know how to fix and reinstate the original launcher. Even after trashing and reinstalling it, it still doesn't work.
Any insight?

Question How can I remove this from home Screen?

Wondering if someone can please help me to remove this circle area. I don't really want that on home screen. I could rather use widget.

It is not possible without root or another launcher.

Home Settings - At A Glance

Google really fakced up this time. Probably said before but they're really lost!

Yes you can, this has been posted and explained here before not too long ago. You need to be rooted and if I'm correct use the xposed framework

Exactly , I was about to post that screenshot to ask lol. Just received 7 pro a hour ago and was setting it up. Thanks bud.

As an alternative, you can just set up another home screen without At A Glance.

Lawnchair or nova your best bet

I used Niagara for a couple of days and paid for the full version this morning. Love the 'empty' screen!

Please tell me how to remove this information from the locked screen? a flashlight also appears instead of the date ((very annoying. There are no lock screen settings in AOSP.

Are you using a Pixel 7?
Your best bet for fixing the flashlight issue is to probably install a Pixel Launcher, stock or modded and customize your At A Glance settings. As for the lock screen weather, not so sure you can turn that one off.

I installed the standard pixel, turned off everything that was possible, the flashlight disappeared, but I can’t remove the date and weather. phone pixel 7 pro

Home Settings >> At a Glance >> See more features >> Disable Weather.
Unfortunately, I am not sure how to remove the date. My apologies there.

It was the same on my 4XL. It's nuts that they put that on the homescreen. Every morning when I turn the phone on, I have to swipe left to get to the homescreen I want to use. I don't want to root, or change the launcher. Back in the day, I was able to choose the homescreen page I wanted.
