Running Nexus one in "Kiosk mode"?

I'm looking to use the Nexus one hardware to create a single purpose device that will run an app at boot up and not allow the user to exit the app. This device will be given to users to take home for days so needs to be tamper-proof. i.e. cannot make calls, cannot SMS, cannot access rest of the OS, etc.
At the Android API level, I believe I can auto-start the app and "disable" the home button but cannot get around the long-press home button recent app list.
One possible solution would be to open it up and physically unplug the buttons' ribbon connector from the PCB.
What I would prefer is to somehow disable the home button using a cooked ROM that will ignore it in this particular app and the app can have some kind of secret way to exit. I do not know how difficult this would be using a rooted Nexus one.
Any input will be greatly appreciated.
Thank you.

You would need to build it from source. (non winzip deving)
If any knowledgeable person get's it it would be pretty easy to boot into recovery and edit system files or wipe it.
The nexus would not be suitable for this because of the nature of the bootloader.

To be honest, I personally think you would be better off building your own device for this. I'm sure that the buttons could be disabled easily enough, but the tamper proof part is a little different.
Main reason:
If you make the device so that you can't boot into recovery, fastboot, or tamper with it in anyway. How would you yourself make any additional modifications to the device?

You guy have some good points.
Maybe it's better off just using rooted stock ROM and set it as home screen then physically disable the hardware buttons. The battery cover will be glued shut to prevent access to SIM and battery anyway
As for making changes to the app, I believe ADK will allow me to update the app through USB. I wonder if its feasible to do auto-update it over network...?

wow your trying to lock the device down sounds like steve jobs lol

would not the best approach to this is to write your app as a home replacement and not show any apps? you could disable access to app drawer and settings, then you would only need to hook/disable home long press.
You wont be able stop a savvy user from flashing something on it easily.

What about setting up a pattern lock and using FLAG_SHOW_WHEN_LOCKED
to display on top of the lock? If the user tries to exit your program they'll be greeted with the pattern lock. Have some timer so your app automatically comes back to the top.

Correct me if I'm wrong, but doesn't the last app list show NO apps if no apps were launched yet?

Yes you're right. I've set my app as home screen replacement and after reboot there wasn't any 'recent app' list
Looks like I don't need a custom ROM after all.

Just out of curiosity, what exactly are you doing with the phone that requires it to be tamper proof?

The absolute minimum requirement is that we have a device we can give to a user of any technical proficiency and allow them to easily record videos and post them directly onto a website from anywhere.

That's an interesting approach, I will have to explore that more.
How can users actually exit the app when it's over the lock screen? Does that mean all buttons including home will not do anything since lock screen is keyguarded? Does touch still register? Is this the workaround that the custom lock screen app uses?

How do you set an app to be the home screen replacement?

disable/enable lock screen

Has anyone found an app that can turn on the lock screen? Plenty can disable the lock screen but I guess KitKat restrictions make it harder to enable it.
I would like to have a quick or automatic way of disabling it when I'm at home then turn it back on when I'm elsewhere, but so far all the apps I've tried fail with the enabling part despite giving them admin access. I guess rooting is the only way round this?

Yup, rooting is just about the only way to get it done. However, if you fiddle around, you just might be able to do it unrooted using this app:
https://play.google.com/store/apps/details?id=com.joaomgcd.autoinput
I think using pin/number password is the only way it could work since, at least when I tried it out, the app only supports tap input, not swipes.
I've successfully used it to enable/disable flight mode, which is otherwise also impossible nowadays without root.
Those new restrictions are completely senseless IMHO.

Root way: combination of Secure Settings and Tasker

Pin unlock doesn't require root. I had to switch to this method.

Thanks all... will try that app and also using just pin unlock

Touchless Control stuck behind PIN lock

I have a XT1053 with stock 4.4.4 and have been having this problem for the last few months.
Somehow, the touchless control is now stuck behind my PIN lock. I have encrypted my phone, so the PIN lock is required. I used to be able to do things like "OK Google Now, what's the weather?" and Google Now would open and show me the weather, or send text messages. Basically the usual use, but recently the touchless control screen doesn't show when I say "OK Google Now", just the PIN screen. I can tell that the voice recognition is happening because Google Now will read me part of the weather, but usually gets cut off as the device goes to sleep before it finishes.
I'm not prompted to say or enter my PIN, I can enter it and get into the Google Now screen but not without using my fingers.
I haven't been able to find anyone else having this particular problem so I don't really know what to try. I've tried disabling Touchless Control, retraining, uninstalling updates (Moto Voice) all to no avail.
Anyone else seeing this? Any ideas?

Oh thank you. I was going nuts because I thought I was the only one. I posted on here as well and no one responded. I have been having this issue for the last few months ever since a Google search app update.
I have an exchange work account set up that forces me to have security on the lock screen. I have the pattern lock set up.
At this point I'm waiting for the lollipop update and hoping that it will fix that problem

Don't know why I didn't think of this before, I uninstalled updates to the Google App and everything is as it was before. If I can find a repository of various versions I will experiment to try and find which version broke.

Just FYI, I got the 5.1 update over the weekend. The updated Moto Voice app, and the latest Google search app are once again working together. I'm able to use the voice control without entering my PIN again.

Same here waiting paid off this time

Real on screen time, tips and tricks to bypass certain issues and some other interesting things to know about the phablet.
I will update the main post everytime when something new is found and keep it up 2 date for users so everyone can see a quick fix or a quick answer.
If you have a fix for anything or information to update the list, please provide it in the reply`s so i can update the main post.
4G/LTE works in:
The Netherlands
Canada
UK
Germany
Spain
Poland
Greece
Russia

Things to know
Max recording resolution is not 2160p as said on the internet but max 1080P.
If you unlock the bootloader it will give you a warning when you boot up the phone saying your phone has been unlocked and can`t be trusted, this is normal when you unlocked the bootloader.
Only 1 of the 2 simcards can use 4g at the time, so there is no 4g for both of the simcards at the same time.
Hold power and volume up when starting the phone to get in the E-recovery menu.
There is only one version of this phone, the chinese one.
This version is called the EDI-AL10, and all the languages are provided on the phone.
Some websites who are selling this phone are telling that this phone misses certain languages such as dutch.
This is not true, every language is present so no worries.
Playstore is not included on the phone, you can simply download it from the HiApp which is already pre-installed on the phone.
The fingerprintscanner can take up to 4 fingers, the fingerprintscanner only works when you activate an unlock code or password to get out of the lockscreen.
Latest rom version is B029.
Previous B027
Previous B022
Previous B017
Quickfixes/Tips and tricks:
Push notifcations
To make push notifications work again create a widget (provided with the app) and place it on your home screen.
The widget will keep the services alive, even when you close the app in the taskmanager.
Make sure you toggle them on in the protected apps menu and put the powerplan on performance mode.
This works for all apps that came with the option to create a widget for it.
Homebutton changer (provided by kalinskym)
To disable HiVoice to allow a different application/ shortcut to work as the Home Button without being rooted. Download Debloater from http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294 and disable HiVoice.apk. (com.huawei.vassistant) After you have done that you won't see HiVoice anymore and will be able to change an app/ shortcut to the home button long press by going into Apps in Settings, clicking on Advance at the bottom. Then click Default app settings and finally Assistance & voice input to change assist app (home button app/shortcut)
One handed mode
To activate one handed mode drag you finger on the navigation bar from left to right to make the screen smaller and using for the right hand.
And drag it from right to left to make the screen smaller for using it with your left hand.
Once activated drag it in the opposite way once to restore full screen or tap once on the screen above that isn't in use.
Knuckle gesture/Splitscreen
To activate "Knuckle gesture" or just splitscreen, swipe your knuckle in the center of the screen from left to right or right to left.
When doing this succesfully the knuckle command will activate splitscreen.
Knuckle gesture/Advanced screenshot
Touch (knock) your knuckle on the screen and keep touching the screen, there will come a blue sparkle once activated drag a circle or square and it will give you a selection field.
On top are some figures you can choose from.
You can now select the part you want the screenshot from and save it directly on to the phone.
Double tap your knuckle on the screen to make a full screenshot. (same as volume down+power button)
Drawing an S on the screen with your knuckle will create a screen shot while it scrolls down the page.
This wil create a screenshot with a larger screenshot containing all the footage on the screen.
Now you don't have to make multiple screenshots to get everything on the screen and down.
(Check screenshot in the attachments)

Please let me know in which country you guys are and if 4g/lte works in your country so i can update the 4g/lte list.

This is useful information. Thanks for that! I have been having an issue with the fingerprint reader taking a second longer to unlock when the phone goes into a deep sleep; However, whenever the screen is recently turned off or when the phone is charging and I try to unlock it with the fingerprint scanner, it works super fast. It's only slow when I initially wake the phone from a deep sleep. Has this happened to you/anyone? I think it may either be an app or marshmallow doze feature. I would appreciate any suggestion/advice. Thanks.

I don`t have any delays with the fingerprint, however i use Smart Unlock to bypass the fingerprint in trusted locations.
Did you already tried to remove the old prints and register new?
Only thing else i can say if thats not working is to factory reset the phone.
on what powerplan did you put your phone? And did you toggle answer calls with fingerprint.
Sounds silly but if thats disabled there is a possibilty that the fingerprint app goes in sleep while activated for answering calls could keep it alive....Always worth trying...

I tried removing the old fingerprints and replaced with new ones. I even did a factory reset. The factory reset did it. That's what leads me to believe it's more an app than marshmallow doze. I just don't know how to identify which app. I even played with turning on all the features of fingerprint scanner. I am on performance mode. It's not a HUGE deal since the phone still unlocks faster than others, but it's a nuance since you know the phone is capable of unlocking faster. If you can think of another recommendation as to identifying the app or cause I would be grateful.

Hi, 4G works in Russia.

I think an easier way to change the voice assistant would be to download the Microsoft Clip Layer app. When it asks you to Tap on Assist app click on that setting and choose something different. I had already had HiVoice disabled when I downloaded the app so if someone else can confirm that it will work I'm sure someone would appreciate it.

4G/Lte works in Melbourne, Australia on Optus

4G/LTE is working fine in Switzerland! (16ms ping, 89Mb/s DL and 20Mb/s in UL in the alps)

Thnx guys, post updated!

Hi, I did a factory reset and confirmed that the Microsoft Clip Layer app does allow you to switch the voice assistant. It is a much easier process than disabling the app and does not require a computer hook-up.

OK Google - PROBLEMS

I use ok google all the time to send texts especially when driving. frequently i am getting an error where she says
"actually, i can't do that while the device is locked" after unlocking with fingerprint it isn't recognized that the device is unlocked for some reason
it seems to be a MIUI problem as there is a huge thread http://en.miui.com/thread-274084-1-1.html
anyone know a solution?
also, one suggestion from Google is to just turn on Trusted Voice so that you can use the OK Google command when the device is locked. when i turn this on the OK Google command does not work and is not recognized no matter what screen i'm on let alone with the device locked
anyone ran into similar problems with the Mix?

I have a similar issue...If I disable lock pattern and then re-enable it it will work. A bit of hit and miss really. Would love a proper solution if there is one.

Same. I can't get it working from a black screen. My other devices will wake up and "listen". On the Mix, I have to activate the screen and then say ok google for it to listen. I did the resetting the lock screen and it did help get ok google to listen on the lock screen. So thanks for that.

I also have the same problem with the latest Google app but it works with version 4.92.16 except that I'm not able to use ok Google from screen off. I hope there's a solution to this

Not sure if i just haven't used OK Google enough yet, or if it has legit fixed the problem...but after converting google to a system app i have not run into this error yet with over 20 times using OK Google. we will see if it holds up.

did you have this problem before making it system app and went away after?

I figured this out.
Browse to Google App > Settings > Voice > "OK Google Detection" and enable "Personal results"
Kind of a workaround, since this allows actions when your device is locked, but works well for me.

I don't have that option for enable Personal results.
I only have
From the Google App
From Any Screen
Trusted Voice
While Driving
All four are enabled.

personal ressults has always been enable and still no joy.

I don't even have while driving.
Only three options.

I don't think it's a MIUI thing. It happens on my Google Pixel XL with the latest Nougat. Same message.
