[Q] Tasker - GPS On/Off?

Anyone finding success with Tasker getting GPS control working on their Nexus 5 (Android 4.4)?
Tasker v4.1
Rooted
Secure Settings Pro/Helper
Example:
Profile>Application "GoogleMaps">New Task ("GPS On")>Plugin>SecureSettings>Edit>HelperActions>GPS>On>Save
ExitTask same as above but GPS>Off
When I launch GoogleMaps I can see Tasker working, but from within Tasker I see an error: "An error occurred while executing Action:GPS"
Any suggestions? Related to "Location Mode" setting approach with "High Accuracy", "Battery Saving", "Device Only" options?
Thanks!

I solved this problem using Helper Alternative in Secure Settings (last option of Helper tab in Secure Settings)
Now with "gps on" action you switch from battery saving mode to high accuracy, and vice versa vith "gps off".
You can also use the action to enable/disable the entire location service but in that case every time you want it on it shows an annoying google location consent disclaimer

Where is the option for battery saving mode or high accuaricy? I set it up only for Location services and the google location consent appear.
Also, is it possible to set it off in another way? because if I click in Tasks button in my phone, it suddenly turns gps off although Maps keeps running in the background

you can switch between battery saving mode and high accuracy toggling the gps option:
gps on -> high accuracy
gps off -> battery saving mode

I use a workaround, I have set tasker to wait 20 seconds before disabling gps when i close apps that need location services, so when I switch to another app it doesn't turn off gps immediatly. I don't know other methods to make tasker consider that the app is running in the background

How do you set tasked to time out after certain time? I keep trying but it just stays on high accuracy

no, you add an action, just hit the plus button>task>wait and set the amount of time you desire

GPS or locational services turning on solution
I created this tasker for if my phone got lost, but could be used for the Google Maps apps or Photo geotagging. This is for phones that are locked and require the google consent notice to be accepted.
Profile: recieved text "lostphone"
Task:
Secure settings: pattern lock disabled
Secure settings: wake phone
WIFI on
Mobile Data on
Secure settings: Location Services Enabled
Wait: 2 seconds
Dpad: Right repeat x2 (this is because the first time it doesn't work)
Dpad: Press repeat x1
Wait: 2 seconds
Secure settings: Pattern lock enabled
Secure settings: lock device
this makes the phone vulnerable but it only takes seconds for the phone to relock itself

Hi,
I just installed tasker app on my Galaxy S7 Edge.
I tried to create a task to switch on GPS when running Pokemon App and then switch off once app is closed.
Task:
1. Launch App
App Pokemon Go Data %LOC
I run the task, as expected, it opens pokemon go app and 4G(gps) icon appears on the upper-left corner of my phone. But the icon won't disappear when I manually turn off the Location on Quick Settings.
Please help how to restore Location icon on-off.
Thank you

Tasker profile help please

Hi, running stock rooted + franco + xposed + gravity box.
So i'm getting back into tasker and these are the profiles i want to create:
-Switch to 3g when internet apps are launched, then back to 2g for signal strength
-Unlock keyguard at home wifi
-turn on data every 30min for sync
-airplane mode at night
-nfc tag on nexus7 for hotspot
-send GPS info once SMS received
-ring phone when SMS received
I've done a lot of searching but can't seem to get airplane mode to toggle with secure settings (something to do with 4.4).
Could someone point me in the right direction? Cheers

You will need Secure Settings from play store for keyguard and airplane mode. It's a Tasker plugin.
Don't do the data toggling. Not a good plan. You can toggle sync with Tasker (auto sync). But cycling data is no good. If you have battery problem, this won't fix it. I have Tasker turn off sync if I drop to EDGE. That's because the syncing times out and keeps the device awake forever. If TMo had usable 2g, it would be a different story.
For signal try Intelli3g. Not sure if that is what you want.
Send GPS coordinates via SMS:
Code:
Profile: Location (3)
Event: Received Text [ Type:Any Sender:C:ANY Content:Where are you? ]
Enter: Location (12)
Task: Location (12)
Run Both Together, Stay Awake
A1: Get Location [ Source:GPS Timeout (Seconds):30 Continue Task Immediately:eek:n Keep Tracking:eek:ff Continue Task After Error:eek:n ]
A2: Variable Set [ Name:%locft To:round(%LOCACC * 3.28084) Do Maths:eek:n Append:eek:ff ]
A3: Variable Set [ Name:%locft To:ft Do Maths:eek:ff Append:eek:n ]
A4: Send SMS [ Number:%SMSRF Message:Battery: %BATT%. Location (%locft): http://maps.google.com/maps?q=%LOC Store In Messaging App:eek:ff Continue Task After Error:eek:n ]
Default location unit is meters, I converted to feet. Not necessary, it was just a reason to play with Tasker some more.
Send different notification when a certain person texts (at a certain day and time)
Code:
Profile: Urgent SMS (25)
Event: Received Text [ Type:Any Sender:person1/person2/person3/person4/person5 Content:* ]
Day: Mon, Tue, Wed, Thu or Fri
Time: From 06:50 Till 16:10

Enter: Urgent SMS (27)
Task: Urgent SMS (27)
A1: Silent Mode [ Mode:eek:ff ]
A2: Notification Volume [ Level:7 Display:eek:ff Sound:eek:ff ]
A3: Wait [ MS:0 Seconds:2 Minutes:0 Hours:0 Days:0 ]
A4: Play Ringtone [ Type:Notification Sound:24 Notification Stream:5 ]
That should get you started. Have fun with Tasker, it's my favorite app If you have any more questions, feel free to ask, but include as much information as possible.

I think you'll have better luck here.
EDIT: Never mind. I see Aerowinder is a Tasker guru.
With respect to the airplane mode problem, Secure Settings Helper is now incompatible with 4.4, and has been replaced by System+ Module. You can update it in settings.

Thanks Aero!
I've happened to find this xposed module: http://repo.xposed.info/module/lv.id.dm.airplanemhx and its working perfectly, so that's that done
Thanks for the GPS task, i had it set up a year and a half ago, but lost my backup whilst switching phones and flashing etc and couldn't remember how i did it
I read Gravity Box recently added a few tasker shortcuts, seems really powerful, i'll see what i can use it for..maybe when i get my Pressy button i'll use tasker + GB to toggle immersive mode...the possibilities!
Will share my profiles here when i get them done, in-case someone finds some use, thanks mate :good:
Edit:
is the battery usage whilst data on and sync off comparable to data off (on 2g)?
Edit2:
Got the following working:
keyguard disabled when wifi connected
airplane overnight
toggle display rotation lock by shaking device
Using 'smart radio' feature of GBox, and turn on sync every half hour when not on wifi.
SMS ring when misplaced phone
SMS Gps when lost /stolen
Now just need to find my nfc tags lol

The SMS GPS coordinates to my contacts (C:ANY) is mostly for work and family. It really has no purpose for lost/stolen applications. For that application, something like Cerberus seems the better option because it can silently track the phone. Also lock, remote wipe, etc. Yes, you could do it with Tasker. But you would have to test it!
You mentioned battery usage with syncing. I will say that the only reason I disable sync when I'm on 2G is because TMo's 2G is unusable. I can sometimes get 5-10kb/s, but most of the time (>90%), there is no data transfer. Just timeouts as far as the eye can see. This causes issues when Google apps trying to sync, because the programmers didn't have the foresight to add timeouts to their sync attempts. Brilliant. I'm an amateur programmer, and that seems like a no-brainer to me. If a condition is likely to happen, you account for it.
I am generally against conditional syncing (what you are after). Syncing with online services (gmail, hangouts, etc). is a fundamental feature of our devices. Disabling it, except under very specific criteria, is pointless. Why even have a smartphone? If you have control over your applications, there is no noticeable battery impact. Some of the bad applications, like Facebook, need to be controlled. Sometimes the app settings are enough, other times, you need Greenify.
All of that said, I do disable sync for things that I don't want syncing. Like Google Photos and People details. I don't want them to sync, ever, for any reason. For a time I also had Keep sync disabled because it was constantly keeping my device awake. That seems to be fixed now, but I still keep an eye on it because I don't trust Google to get it right.

Good advice.
I already have Cerberus installed in system partition, but I prefer tasker for locating.
A year ago I lost my phone and just my luck Gps and data were off unfortunately, making Cerberus quite useless as it can't switch those on.
My tasker profile was set to turn on both and add an additional lockscreen pin, so worked out in the end.
I think it pays to not put all your eggs in one basket

You need Secure Settings to enable GPS in KitKat. The Tasker toggle doesn't work. Just a tip, not sure if you were aware.

Yep, Airplane mode also, but you need system+ module. Also removed the xposed module I mentioned earlier, as secure settings is working now.
Gonna test my profiles for a bit longer then post them here soon. Thanks mate

[TASKER] Share your best and favorite Tasker profiles for OnePlus 2!

Hi fellow XDA members, I just came across this awesome app called Tasker. I am still trying to figure it out and learning about it but i know it got huge potential to automate our devices. Many of you must be experts in using it. So I created this thread for all to share their best and favourite Tasker profiles for OnePlus 2. Looking forward to see some wonderful ideas to automate our beloved OnePlus 2.

tasker is not device or rom specific at all, hence i don't think that people ( experienced users ) who us tasker in a sophisticated manner would read and post much in this thread, there are dedicated tasker thread. just stumbled in to see what tasker profiles (tasks) would be especially for the OP2 and as suspected, there are none yet.

I've been looking for a way to use the fingerprint sensor, to secure certain apps, such that only I can access them with my fingerprint. I haven't succeeded yet, so if anyone has an Idea I would appreciate it.

That's a great idea. Experts, please shed some light on this if it's possible or not.

I don't own a OPO, but I imagine the profiles I run would work on any android. I've only got a few at the moment, some I ditched because I no longer had a use for them since getting on PAC ROM.
Current profiles are:
ClearCache. Autolaunches the Fast Cache Cleaner app everyday at 6:00PM. The app has no UI, so it doesn't interfere with what I'm doing at the time and just quietly clears cache in the background.
LowerMediaVolume: When headphones are plugged in, media volume gets reset to 2. Got sick of scaring the pants off myself when I'd go to listen to music and had forgotten my media volume was maxed out...
TurnGPSOnWhenWazeIsLaunched: I use Waze as my navigator, so I have it set to automatically turn GPS on (through the Secure Settings plugin) when the app is launched. Also included an exit task so once I leave navigation, GPS will shut off as well.
BirthControlTxt and CleaningReminder: They're similar profiles for my bad memory. Everyday at 11:45PM, my phone sends me an SMS reminding me to take my pill (I also have an alarm for this set at 11, this alert is a fallback just in case my alarm goofs). CleaningReminder is set to go off every Monday, but I only clean the factory every other Tuesday. So I set the cool down period to every 13 days, and hopefully that will 'disable' the alert every other Monday. I just made that one so I haven't gotten to test that. In the past, I also had an AutoReboot profile to reboot the phone everyday at 7AM, but I haven't gotten ballsy enough to try it since switching to a somewhat unstable ROM

Certainly.
Profile: Application/Waze
Task: Plugin/Secure Settings/System + Actions/GPS/Set ON
Exit task (to create exit tasker: once you have built the above Task, go into your profiles, expand your Waze profile, and long press on your task, then select to add an exit task): Plugin/Secure Settings/System + Actions/GPS/Set OFF.
Results may vary from device to device. This profile worked great when I had a Jellybean stock ROM, now I'm running PAC on 5.1 and while it does work, it occasionally will put my GPS on 'device only' instead of high accuracy, so for reliablity I just toggle GPS myself in my notification bar until I think or hear of a way to do this more reliably in Tasker.

I did it that way but wasn't working...
Cleaned flashed oxygen now works

Need some help...
Trying to use Tasker to create an action to the 4636 Hidden Menu, so then can export it to an app for quick access.
Was originally trying to do it the phone but didn't work...
Right now I'm trying:
System > Send Intent
Action: android.intent.action.MAIN
Package: com.android.settings
Class: com.android.settings.TestingSettings
Still nothing though
Thanks

Tasker for dark mode?
I'm wondering if Tasker can be used to turn on dark mode on the Oneplus 2 at a specific time of the day. What task option do I use?

I did the same with Google Maps..

ENTRY TASK (GPSMax):

[Flash "High Accuracy GPS enabled"]
EXIT TASK (GPSMin):

I always have battery seving location ON, so I just need to turn on High Accuracy while I'm using GMaps.
You have to install Secure Settings plugin and enable its XPosed Module

Did you try putting a 1 second Wait at the beginning? Maybe the phone just needs some time..
And use a Flash in order to see if the profile is fired

How do I do that? Can you please give the exact options to set?

Tasker and Touchwiz

I came from an LG G3 with CM12 and then 13 so I have never had problems with tasker just working. When I tried to set up some of the most basic tasker profiles I ran into problems on the Note 5. I'm sure this post is similar to many before it but I figured it might just help out someone that was in my situation.
The first profile I just had to have:
When phone connects to my car BT head unit it will start wifi hotspot. I tried every setting I could and even tried using Fox Fi to get it to work with just tasker...then I stumbled upon AutoInput. Its great, you can do things that I previously assumed you needed root for.
I was able to set up my phone to do just what I wanted using a combination of the AutoInput apps built in task creator and inputing manual coordinates for touches. I got tasker to do just what I wanted it to do, albeit in a much more round about way than usual.
The most simplified version of the task I could put together was:
1. AutoInput Unlock screen
2. AutoInput global action: quick settings
3. Task wait 370ms (can vary but I found you had to have a least some wait time or it would not consistently register the next touch)
4. AutoInput Action: Point value 154,676 (Use dev settings and turn on show pointer to see what the x,y coordinates of your hotspot switch is)
5. Task wait 470ms (again same as #3)
6. AutoInput Action: point value 1212,1544
7. Task Wait 5 sec (I need to play around with this a little more, I'm sure it could be less)
8. Display: System Lock
I would like to here from others on how they have implemented tasker in touchwiz. And please let me know if I was just an amature and didnt know how to do this with tasker alone.

Question How to prevent apps from auto starting at boot

Hello,
All is in the topic, I've got an app that starts automatically when my phone is powered on.
It is Aircall, an app I use for passing and receiving calls at work.
I would like this app not to start automatically each time I power on the phone.
Is there a setting for disabling some apps to autostart ? Or an app you can advise ?
Thanks for your help.

Check the app's preferences to see if there are options.
In the Android settings, go to Apps > See All > (your app. eg Air Call) > App battery usage and set it to 'restricted.' This will greatly restrict an app's ability to do many things in the background.
Other than that, you'd have to root your device to get any more control over the app using something like Servicely (Google Play Store), My Android Tools (apkmirror.com), Permission Manager X (fdroid), AppOppsX (fdroid), or Blocker (fdroid) to control the app's broadcast receivers. Apps can choose to respond to various phone states such as when a boot is completed, when network connectivity changes, power is connected/disconnected, etc. It can take some aggressive action to fully prevent an app from always running.
If you're just annoyed by a notification icon in your notification area you can always disable that app's notification so it doesn't appear.
I have tried all of these things to control apps but if apps use a lot of various broadcast receivers they will find ways to keep running. You may find stopping it to have unintended consequences. It being a work app, I'd consider simply disabling the app's notificaiton if it has a persistent notifcation or something. The next step would be to restrict the app as in 2. The most aggressive thing is to root and tinker with its broadcast receivers.

Hello jawz101,
Thank you very much for this very complete answer.
All your precise instructions are very interesting.
I'll have a look at all these solutions.
Thanks again.

I am not sure about straight forward solution. But I would like to use Greenify app. Add apps to it once and run it once everytime you restart your phone.
