[Q] App to warm-start GPS after reboot? - Android Q&A, Help & Troubleshooting

As everyone knows, GPS cold-start is very slow.
Is anyone aware of an app which would kick off GPS after reboot so that it acquires the basic satellite and location information needed to do a warm- or hot-start later on? Seems like it would be an easy thing to do -- probably preferably delayed so that other more important boot-time processes can do their thing.
Note I'm not interested in one of those scripting apps, I'd prefer a dedicated app, if one exists.

[Q] Google NAV Feature questions

So i take it based on whats out, google NAV is the best GPS NAV app out there on this phone. Of course being free has alot to do with it, but I find a few features that it is lacking. Does Google nav have a way to search for waypoints,POI, save custom address, change alternate routes (fastest-shortest), day/night switching, map updates or any other hidden feature that i may have missed.
I know i'm asking too much for a free app, but its google..seems like they give away apps all the time.
If there is an app better, please also recommend
Day/night switching happens automatically.. Don't know what the threshold is, but I'd imagine it's based around sunrise/sunset times for your location. Other items on your list.. Not sure about.
I have to say Google Maps has done me a multitude of good since my first Android. I have watched the app develop as I used it and heres what I think...
Recently GM added multiple subapps to GM: Latitude, Maps, Navigation, and Places. Latitude allows you to share and view you and your friends locations. Can be really handy for some.
Maps is what it is....a mapping programs.
Navigate is my favorite. Clicl this and you can speak or type or choose from a saved address. Pretty nice too and you CAN choose route information and rerouting its pretty nice. Set your gps start and end....go drive and play with you phone on the Nav portion and youll find all the options. Plus multiple methods of getting to and from as well.
Places is basically POI layed out nicely anyone can quickly find whatever they need.
I swear by gmaps and wont do anything elzeq
On the first screen of Navigation, click on the "gear" icon at the top and you can choose "Avoid highways" and/or "Avoid tolls". Not earth shattering settings, but certainly a step in the right direction. I think this was around a couple of updates ago. I have CoPilot Live installed on my phone and I always go to Google Navigation when I need directions, especially where it's integrated into the system much better (navigating to contacts, address links, etc).
Thanks guys, this makes me like the google map even more..However I don't see why google made sub applications to work with G. maps...maybe they shoulda just made 1 application to do all the functionality instead of running map, nav, location, places, and whatever else they come up with..too many apps to run instead of being a feature that should be built as one..in my opinion
Not complaining just sharing my thoughts.
Just a guess, but I'd imagine separating is so the carriers can customize the basic Maps app, without having to worry about messing with the other advanced features.

[Q] App for intercepting data connections

Hi,
I thought maybe you guys, if anyone, would know. I am looking for an app that can:
- make a log of all the other apps, including stock ones, that make attempts or actual connections to the internet, and at what time
- be able to intercept those connections
- preferably I would create a white list of apps that are allowed to connect, but others do not have permission.
Purposes include:
- saving on bandwidth in poorer countries where internet is expensive.
- making sure apps or malware doesn't try to send off my data when it shouldn't be.
- prevent annoying background sync/apps from running when I don't want them
I find it strange that we either give all the permissions the app wants, or it doesn't work. Why can't we restrict their internet access?
Does this sound feasible? Does it already exist?
I'm rooted and using an Asus Transformer.
Thanks for any help
Try DroidWall. (root required)
It can block apps from connecting to the internet on an per-app based system.
But i don't think it has any kind of log or similar (haven't used it for a while, so might have been upgraded)
it looks like that does exactly what I needed, although I have to re-root my device for it to work again. Anyway, thanks for the tip
droidwall
droid wall definitely and yes it requires root.

[Q] App to track family members (with their permission)

I saw another thread about hiding apps in some guy's wife's phone to track her. I'm looking for something similar with my wife, but it does not need to be hidden. Mainly to be used because I commute quite a distance and this would let her know how close I am to home (rather than having me text while driving). Similarly for her when she's travelling.
Just an app that would:-
1. Allow me to see where she is (and vice-versa)
2. Use GPS if on, otherwise fall back on net information
3. Not use SMSes (some sort of internet-based communication between phones)
I could probably hack something up using Tasker but her phone isn't rooted like mine is so the capabilities for GPS etc are a bit more limited (and time is limited, of course).
Thanks!
Already built in

You can actually do this with the built in google maps application. It's called local/latitude. You can share where you are and control who sees it an when. Go ahead and look into it. Much better then downloading another app IMHO.
See here: Google search latitude android
Thanks, yeah I know about latitude features but it seems to lack a way to "ping" the other party with the equivalent of "hey, I've reached road X"
Sent from my GT-P7500 using Tapatalk HD
Use an app called Backitude from the Play Store. Latitude updates pretty arbitrarily on its own. This app allows you to control how and when it updates, and also let's another person force an update on your phone by sending an SMS. It's all Internet based except the update triggering part. You can also use the tracking features of Cerberus, another app in the Play Store.

[APP] Standalone navigation app for Wear OS!

I made a standalone navigation app for Wear OS! Here's the link to the app: https://play.google.com/store/apps/details?id=uk.co.onibaku.standalonewearmap
Here's the full description on the app so you can get a glance at the features:
Users can type in a location, or long press on the map to input a destination. They can choose to travel via walking, cycling or car.
The app will navigate the user from their current location to the destination using turn-by-turn navigation. Each step is highlighted on the path, with text to show you what action to take, and how long until you reach that step. The map rotates along with the device, so will follow the forward-facing direction of the watch.
The app only needs an internet connection for the initial retrieval of the directions. After that, it solely relies on GPS until the user arrives at the destination.
This (obviously) only works on watches that have GPS.
If you have any suggestions at all, I'd love to know them.
The next feature I plan to implement is importing a GPX file in from Google Drive, so you can navigate a more unorthodox/scenic route, which would suits cyclists. I initially developed this for when I go cycling, as we don't usually want to take the fastest route somewhere.
Let me know if there any burning features that are needed in this, and I'll do my best to deliver. This is a small side-project, so I don't have too much time to work on it, but I find it quite useful personally, and I hope others will, too.
Someone suggested I release a demo version so people can try it and see if they wish to buy it. I have released one here
It only has the dropped pin functionality, and only allows walking as a navigation mode. The zoom is also locked.

This is looking really good. I want true standalone navigation on my Huawei Watch 2 4G. It has a sim so loads the route standalone and seems to be able to do everything expected...i'm trying the demo version now.
One question though...unless i'm missing something..how do you exit the app? I'm currently having to force close it.
(And as a side note have you checked out the Wear OS app Ghostracer? You can import a gpx file and follow your progress on a map on the watch. Maps are downloadable to the watch, although ive never tried that. My watch has a sim so updates the map as im riding using the watches data. Heavy on the battery though.)

I had not realised that the app does not cease to use GPS whilst it is in sleep mode, so I have added a button to exit the app properly when you drag down. I've just released it now.
I have had a look at it, but it doesn't seem to work unless you have an android phone. I am currently looking into offline maps and importing GPX files. Do you know if it does that via the android app, and how it imports it? I was looking to use Google drive, as that seems to be the only viable storage solution supported on Wear atm.

Thankyou for the exit button, works great. Having tested the demo app i'm happy, and I will purchase. One further comment, the battery drain is heavy, as expected. Any chance of an ambient mode while the map is running to save battery? I may be pushing my luck, but I can only ask!
Ghostracer does indeed need a companion Android app on the phone. The gpx file is loaded into the app on the phone (using a file manager) then passed to the Ghostracer app on the watch. Maps are treated the same, but I just use the data from my sim in the watch to load maps as I ride when needed. You can follow a gpx route standalone on the watch in a similar way to following the route on your app. I am not connected to Ghostracer in any way, I just think its a wonderful app for cyclists and runners (within the watches battery limitations). And the free version allows you to test all its features. It might not be right for you, but it was worth a mention based on what you said earlier. (And the map screen has an ambient mode.... )

Great . I did play around with the ambient mode, but it was just the same as the standard google maps ambient mode. It takes away the turn-by-turn, location, and path. If I could persist these, and set the GPS to update every 30 secs - 1 minute, I'd probably keep it, but I'm not sure how. I'd like to stick in options to set the GPS update frequency, or have the screen turn back on only for upcoming turns.
That's really cool! That's essentially what I would have liked on my watch but standalone. I really don't like the idea that you HAVE to use a companion app, especially when it's not available for iOS. I know they're competing watches, but I love the price point of android watches compared to Apple's, and their features shouldn't pale in comparison by way of hardware.
How does their ambient map work, if you don't mind me asking? I'd like to look into it. What does their paid version allow you to do? I only had a paid version before someone mentioned to put the free one on, just to give people a flavour of it. I tried to emphasise the main bit, which was the turn-by-turn navigation. The search and other transportation modes were secondary.
Cheers for the feedback and suggestions, though! I really do appreciate it! Let me know if there's anything else you'd like.

Ghostracers ambient map is black background with white markings until you lift your wrist...but that might not work when using your app while driving (watch off the wrist?).
I've now purchased your app (Google made that hard work!)...all still good. One question...when I zoom the map in the map un-zooms straight back. Any way to make the zoom stick?

Do the markings include the path/trail? I've used the black background one before, and the building outlines are (kinda) white. Yeah, I do have my watch affixed to my handlebars on my bicycle.
Great - Thanks! It's much appreciated! How come it was hard work, if you don't mind me asking? Ah, yep. That was one of the first things I forgot to change! I completely forgot about it! I've made it so that if you zoom/pan, it'll stick unless you press the "my location" button again.

Hi ruggs1234, it was a long time since you wrote your experience with this app. I downloaded the demo today and I tested it. Looks like since last Google's update, the huawei watch 2 doesn't use its built-in standalone GPS. Please, would you mind to check whether you are having this problem now? The only way I got it work was by connecting the watch to a phone through Bluetooth.
Kind regards, Angel

Hello Angel,
The app still works ok on my watch, I tested it yesterday.
With my phone switched OFF I use my watches inbuilt sim to start the route (the app needs data to download the initial route, it can use the connected mobile but mine was switched off). I then switch off the sim in my watch and follow the route using only the gps in the watch. The app worked as it always has.
HOWEVER, my watch isn't running the latest version of Wear OS (it's running Wear OS 2.0, Home app 2.16). I never update anything Google if i'm not forced too, their updates often break more things than they fix. Everything I use on the watch works great and i'd like it to stay that way....
Hi,
well, I gave it a test (full paid version) - TicWatch 3 Pro 4g/LTE (all up to date). It doesn't work. All tested in standalone mode (no phone involved).
- app crashes when there is no GPS fix (GPS is on, but no fix yet)
- when I set an route to navigate (pin or search) it just endlessly shows progress circle and nothing else happens (GPS on with fix, LTE on and working)
So...
BR, Doman.
I installed the Demo version on my ticwatch 3 pro gps (updated everything to current versions and no modifications (yet))
App is starting, map is not showing, just the gps location button on the left and a white/grey screen. I can pin a location on the white screen and its actually getting a location next to me and tries to route there - but without any map showing.
Any app for Gear S3 ?

GPS clock synchronisation?

Is it possible to write an app for Stratos/Pace which would use data from GPS to synchronise internal clock? GPS satelites all have atomic clocks on board so the time stamps they send are super precise as that's how triangulation of the position is achieved. I'm wondering if something like this would be at all doable considering all the OS constraints?
Possible, it is. But root is required to change date/time, so probably it wouldn't be that useful...

lfom already has good answers above.
Here is just my 2 cents.
The OS on the watch is Android 5.1, so basically any Android app (for MIPS) works on it.
Android, however, requires an app with system permission to change time, so you need root or make the app a system app.
That being said, I believe the Network Time Protocol (NTP) provides as accurate time as GPS and it's easier to deal with NTP in programming.
There are already a few existing Android apps syncing time using GPS/NTP, but those are not designed for small screens. My favorite one is called ClockSync which utilises NTP, requires Internet access, and works on my rooted watch.
I am on rooted Stratos. This is massively interesting to me. This is basically one of two things I need to get rid of official Huami spyware sending the data god knows where. That shady app always first syncs your health records and only then gets almanac data. If there were a way to do that without them, it would remove a huge dependency on their servers for the future. I mean they can turn off the infra in one year and GPS will be virtually unusable. It'd take forever to get a fix.
@anox, do you have some app for this? I found the only app with aGPS xtra.bin download possibility so far here: https://play.google.com/store/apps/details?id=by.zatta.agps
They claim it works for Qualcomm chips (but I have no idea what powers Stratos):
aGPS Alamanacs
Derek Gordon maintains a special aGPS almanac for devices using Qualcomm or similar chipsets. This xtra.bin data file is updated every 30 minutes and is located on a content delivery system maintained by the generous donations of ther userbase.

A few others I've tried on my phones are GPS Status & Tool Box and GPS Test. Pace/Stratos has Ingenic M200S chip.
If I remember it correctly, GPS Test runs on my Pace as well, though I've never tried its aGPS data download on the watch. Here's the link. https://play.google.com/store/apps/details?id=com.chartcross.gpstest
