Auto power on/off with loss or gain of power? - General Questions and Answers

I am planning a install of a tablet with cm9 into my vehicle and was wondering if there is a way to make the device auto turn on when i start my car and auto shutdown when i turn vehicle off?
This will be a Kindle Fire as it is the exact measurements i need and will have a custom rom on it.
Any help with this is much appreciated.

Look into the application Tasker. I'm not sure about automatically turning back on, but it will certainly turn it off for you.
However, just scaling down the CPU, turning off all radios, and the screen when not powered may suit your needs, and can be more easily done with Tasker.

the kindle fire is android based and it auto turns on with power..
Also this app enables this feature on specific device https://www.google.com/url?sa=t&rct...NyyCfaUMp8XfX5OYg&sig2=LshdXHh-_Rn_iS-jrJB0nQ
guess my solution is done, even after installing custom rom on kindle fire it auto turns on with power source.

Anyone know how to get a device to auto power off with loss of power?
If your going to say Tasker, please explain how you got it to work

[Q] New app to switch on/off automatically your phone

Hi all.
I would like to know if there is an app to switch on/off your windows phone automatically. I miss it when i changed from Blackberry to WP. For example i often forget to switch off my phone at night so this app would be very useful for me.
Thanks

I guess it is not a problem to write the aplication witch is able to turn of your phone. But how the hell could aplication turn ON the phone back, if it is tourtned off. For example try to turn on your PC with some kind of application. I guess you get the point.
Of course i get it, even if i'm not a developer. It would be great to have just an auto-switching off app. However, don't know how, blackberry has got it.
I would be really pleased if someone wrote this app to switch off the phone.
thanks again
I actually don't think blackberries turn off completely until the battery is either completely dead or removed. I know when a blackberry is "off" it still has the ability to turn back on when an alarm is going off so I would assume that it just goes into a low power standby state. However, when you turn off Windows Phone, it's off.
This should be posted @ [email protected] section.
I didn't do that because i must write 10 post before writing in that section
Actually, my PC will turn on at a given time, but I don't believe these phones can do the same. Also, if it does turn off at a certain time, you would not be able to have it plugged into a charger. When WP is plugged in, it automatically turns on. I believe that's a hardware design.
Reboot App Perhaps???
I DONT KNOW ABOUT A SHUT DOWN APP BUT HERE IS A REBOOT... PRE-MANGO
If you have pre-Mango (pre-7712+) you can use the attached .xap, its an app that was developed by someone here at the forums... I changed the icon for the start screen but that is all...
For shutdown, just hold the pwr button at this time... sorry... jejeje
I think what he's looking for (as I am) is a version of Phone Alarm or Pocket Phone Zen. They automatically turn things like WIFI, BT, Phone, etc. on or off at preset times. PA can also do that when plugged into a charger so BT will turn on when the phone's in the car holder for hands free. I haven't been able find anything in the Marketplace.
For restart phone on Mango try that app: http://forum.xda-developers.com/showthread.php?t=1333740
I use for shut off/on power button.
In Blackberry when you press the power button off it does not get really turned off. Its in sleep mode which actually just closes the user state but the kernel keeps ticking and thats the reason any app in background hooked to kernel can turn it on which is actually waking it up from sleep.
Moreover in sleep mode everything used to get shut off i.e call it airplane mode. So if somebody can make a WP app which can just turn on and turn off the airplane mode, it should work for you.
Have a look at Phone Alarm for WM 6.x It is able to do so much more. Things I would like to see in an app for WP7 are:
scheduled on/off of WIFI, BT, phone, GPS, data connection.
scheduled sync of email at longer intervals like every 6 hours (WP7 max is 2 -not everyone has a data flatrate.)
Scheduled and location based volume adjustment. (quiet at home, loud in the car, etc.)
BT, GPS auto-on if charging ("Car" profile if charging, see next point)
Profiles that can be changed with one click. (for example "Meeting" profile turns off sound, reduces display brightness, turns off WIFI, turns on BT etc.)
doesn't have to be cost free but does need to be bug free
Cheers

turning wifi automatically off

I have tried a few auto turn off apps on my transformer while screen is off but WIFI still stays on. These Apps work well on My Samsung galaxy.
Another thing I noticed is that everytime I set the WIFI disconnect policy to turn off wifi when screen is off. The setting goes back to "never". Not sure how it gets reset, and maybe thats why these apps do not work.
Any ideas?
revolver parts wit revolver rom, the revolver parts app let you turn of wifi automatic
I am on stock rom for now, until I read thru all of the forum and get comfortable with switching rom. I am rooted atleast and have CWM installed.
So is there any other app?
Auto airplane mode from the market. It turned off for me.
Try with Tasker
will try auto airplane mode but I need something that turns off wifi when screen goes off.
Also, afraid to buy tasker before I know it works.

Auto Airplane Mode will turn WiFi off when screen shut off.
I use it, work great. The one I use for some reason is not in the market any more
but there are others.
TRIED auto airplane and did not work.
I think the issue is that something always changes the setting to never turn wifi off . Instead of what I keep on setting it to disable wifi when screen is off.
Is there a app that is changing the wifi policy settings>?
green power app fixed my problem. found this out in another thread.
I'm using tasker with a profile to turn airplane mode on 5 minutes after display goes down. It doesn't sleep if there are certain apps which require internet connection (tunein radio for example) and turns off airplane mode for 1 minute every 30 minutes.
I'd never used tasker before, i own an Android phone too, but i found it simply amazing!
Seems like you have an app that wants to keep wifi on. If I were you, I'd try to get to the bottom of this and figure out which app is causing this issue to occur. In fact, the culprit sounds fishy.

Problem with tasker application

Hey guys,
I recently downloaded the tasker application. Currently I am trying to get the brightness to 100% when it is receiving power (plugged in), and 25% brightness when it is removed. I tried enabling the check box which says "Immediate Effect." However, I still have to turn the screen on and off for it to work. I also tried using automateit, same problem, I must turn off and on the display. I did make a crude workaround by having tasker turn off and on the display so the brightness would adjust, but I would rather have it adjust without turnong on/off the screen. Are there any apps that could be interfering with it? I am using an unrooted ICS Droid Razr.
If there are any other posts which could help with this problem please link? (I couldn't find any)
Thanks

[Q] Power saving through Tasker

I consider our Tablet to be different than a phone, in the sense that when we turn off the screen, we dont need all the background functions still running. Currently I see TF101 deep sleep battery drain caused by many different functions running in the backend...for example the location services api.
I was thinking of creating a Tasker script that turns off as many different things as possible a few minutes after the screen is turned off.....And turns them back on when the device is unlocked.
I didn't want to spend time reinventing the wheel if this has already been done....
Anyone already try this? Results?
thanks.
I decided I was over-thinking it...and went with tasker scripts to
a) Auto Turn on Airplane mode when the screen goes off
b) Auto Turn off Airplane mode when the device is unlocked.
(This involved using the "Secure Settings" plugin app to allow Airplane mode via tasker on 4.2 JB)
So far the results have been good. i don't see those map api's being called during deep sleep.

[Tasker] Profiles to toggle Flash Notification setting automatically

Description
In light of not having a dedicated notification LED I set up some Tasker profiles to toggle the Accessibility setting Flash Notifications. I don't want it flashing while I'm using my phone, or while in my car on my wireless charging mount. This consists of 2 profiles and four tasks.
First profile will disable Flash Notifications when your screen is on and enable it when your screen is off, unless the Car profile says it's in your car and on your charger.
Second profile will disable Flash Notifications when it's connected to your car's Bluetooth (be sure to set it to your cars Bluetooth address), AND it's on the charger, unless the Screen profile says the screen is on, in which case the Flash Notifications will remain disabled until you turn you screen off. In my car, I use a wireless charger, so taking it off the charger disconnects power, and putting it back on the mount reconnects power automatically. My idea was that I don't want the Flash distracting other drivers, cuz they have a hard enough time being competent as it is. If you don't use a wireless charger or don't have Bluetooth in your car, you might have to tweak the activation of this profile to your specific case.
I have never shared a Tasker Profile before, so if anyone's interested in this and it doesn't import or something let me know.

I am providing both downloadable attachments, and links to download from Tasker's site. You must also have Tasker and Tasker's helper app "Tasker Settings" installed.

I don't recall having to use adb to grant Tasker special permissions, but I will be doing a fresh install of this on my wife's phone tomorrow and will update if you need to.

Useful. Thanks.

I'm a complete idiot when it comes to Tasker. I have compiled ROMs from source, made many Smali edits, built themes (all many years ago when I had time) but never spent the time to figure out Tasker.
I would like Tasker to disable Holey Light (see screenshot) when Do not disturb is turned on and re-enable it when Do not disturb is turned off. Would you know how to (or could you make a profile) do this?

I second this!!!!
Tasker looks like a super useful tool, but f*** why make it so complicated and not user friendly.
I recently tried MacroDroid and like it more, but its definitely limited compared to Tasker from what I've learned, but it did work while I used it.
To disable Holey Light while in DND would be very nice to have. Please advise.

I'm not sure if Tasker can change the settings of another app without said app already being programmed to be controlled by Tasker. I'll have to see if this is possible.
Also, considering Holey Light is still in beta and being developed, you might try contacting Chainfire and seeing if he can add this setting to the app natively.

He's looking into adding Do not disturb but I already found a workaround for my problem. In Holey Light I just turn off for it to work when charging and screen is off. I charge my phone every night so it works out fine for me.

Only way I can think of having Tasker control it as is, would be to enable disable notification permissions or Accessibility service, both of which require root to do and I have the unrootable US Snapdragon variant.
On another note, Sammy has already added a variation of ring notifications that I'm sure they will expand on. As if now, it works with system apps with screen on or off, and with user apps with screen on.

I appreciate it, I also have the unrootable US Snapdragon.
Samsung's current implementation of the notification light is just plain useless. It stays on for like 5 seconds.
Holey Light is working perfectly for me the way I have it set up.
