So it appears that the Acer Iconia A3-A10 tablet that I have does have
internal GPS - to the extent that it is something I can turn on or off
in the Settings menu.

But in order to even have access to the GPS on/off button, I have to
agree to put a checkmark in the box that says:

--------
Access to my location
Let apps that have asked your permission use your location information
--------

If I say no to that, the "Location Sources - GPS satellites" setting is
set to OFF and is grey'd out.

If I say yes, the GPS Satellites setting is set to on (and is no longer
grey'd out) but in the foreground a window pops up saying:

------------
Location Consent

Allow Google's location service to collect anonymous location data.
Some data may be stored on your device. Collection may occur even when
no apps are running.

Disagree Agree
------------

If I select Disagree, the popup box goes away, but GPS satellites
setting is still active (on) and not grey'd out.

But I'm not sure what I can do at this point to get some idea what the
GPS is doing - for example does it have a satellite fix, can I get my
current coordinates (latitude/longitude) or can I open a map program and
see my location.

What I'm wondering about is - is there a map program I can download
(that has a full set of, say, US/Canada maps) and use this tablet as if
it were a PURE GPS map device (like Garmin, TomTom) where the tablet has
no desire or need to communicate anything back to anyone about where I
am - because it has everything it needs (map data + gps data) to
function in a "stand-alone" mode - just as devices like Garmin or TomTom
have no need (or even ability) to transmit anything back to anyone else
to perform their geolocation and display functions for the user.

I use this <http://mobiwia.com/gpsstatus>

It's also available in the Play Store (free and paid versions), but I
have a feeling if you're averse to letting Google know where you are,
you might not want to use their store either ...

At that point you have agreed to allow those apps that have the right (given at
installation time) to access your GPS data actually do so (you might not want
them to able to all the time so as to save battery life for example, or to
restrict GPS usage to times when /you/ want GPS to be used).

Note that if GPS is turned off, apps that are allowed to use location info at
all can still get less accurate info via the cell-tower (I haven't explored
what happens in this case on a device with no 3/4G access).

This is a separate setting that applies to Google-supplied services (Google
Now, Google search etc). As far as I know it controls Google's access to /any/
location info -- not just that acquired by GPS. So at this point (I would
expect -- haven't tried it) most mapping/navigation apps (of which there are
huge numbers) will be able to use GPS to find your current location (etc), but
the Google Maps app won't. (If it works the way I think it does, then I'm not
too happy about that since I want to use Google Maps, but don't want arbitrary
Google-supplied apps to share my location with Google.)

Yes, as I mentioned above there are many, many, of them. Some are free (and
mostly either use Google Map data or OSM data), others are not free (but not
expensive either), others still use a subscription model.

As far as I know they all /can/ work without connecting to any server anywhere
(i.e. offline), but some -- Google maps is one -- require access to central
servers to provide other services such as directions (and ads).

How much data they /really/ send to their motherships is anyone's guess (it
shouldn't be like that, but it is). But if you have both WiFi and "Mobile Data
Traffic" turned off, then at least they aren't sending turn-by-turn updates
anywhere (but the cell-phone company is still tracking you).

What I don't get is this:

Why isin't there something in the Android Settings menu that can show me
some basic GPS data -like at least the current lat/long coordinates -
without needing explicit permission from me to allow something - because
you would think that the OS would have implicit rights to access and
display GPS coordinates from it's own internal receiver without needing
my permission.

So I should have the ability to turn on and off the GPS receiver -
without being asked to give third-party apps OR the android OS any sort
of access permission. And if I turn it on, the OS should at least be
able to tell me my coordinates. Anything beyond that (such as map
services or other apps that can use GPS data) would need permission.

Why is it always assumed here that these devices have cellular or 3G
data service?

Do you not realize that there are a class of android devices (tablets)
that are wifi / bluetooth only?

(and why Android itself is incapable of not knowing it does not have
cellular capability, or that it is not being run on a phone, is just
plain stupid. On my Acer tablet, there are many menus that make
reference to "phone" when clearly the tablet is not a phone).

What-ever default or installed apps (or system services) are on this
Acer Iconia A3-A10 tablet that can interact with the GPS to tell me
*something* about the state of the GPS receiver or GPS data the device
is receiving, either I haven't discovered those apps - or figured out a
way to navigate to the relavent system menu to show said data to me.

During these investigations I have opened / launched some sort of google
map thing, but the first thing it did was pop up some permission box
(again about location privacy or some such) to which I declined and the
map thing went away.

There are?

I'm talking about having many mb or even gb worth of map data (along
with data about locations of stores, resturants, other landmarks or
points of interest, etc).

There are such packages for android available for download?

Try OSMAnd (Open Street Maps for Android). You can save maps to your
device, and navigate using GPS without any internet connection.

Probably because GPS soaks up power. So it isn't turned on unless some app
explicitly asks for it.

Remember that one of Android's main design principles is to minimise power
consumption.

A simple, free, app such as "GPS Status & Toolbox"
(https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2), or its
equivalents, will tell you basic GPS info such as Lat/Long, number of
satellites fixed, etc. Note that Android will turn off GPS as soon as you
switch away to a different app (that's just how Android works). If you want to
keep the GPS active then use an app that explicitly tells Android "keep the GPS
on in the background" -- the only ones I know of are apps with the ability to
do tracking, such as "GPS Essentials"
(https://play.google.com/store/apps/details?id=com.mictale.gpsessentials) which
provides a bunch of mapping-related stuff on top of basic GPS data.

Tough! You can't.

Because for most people that's true. It's not true for me (2 devices without
SIM slot, 1 with it but not occupied, 1 with SIM installed) and apparently not
for you either. But we're in the minority.

Sigh... Yes. Of course.

Android itself is perfectly capable of doing that, and actually does so. There
are many lazily written apps, though, that don't use that kind of information
and some of the "system" apps on your device may well be among them.

Makes sense. Google maps requires that you agree to give location info /to
Google/, and if you don't agree then it won't run. (Actually I'm not sure that
it won't run at all, but it certainly won't show your current location.)

Yes. Search the archives of this group, sometimes it seems we talk about
little else (that and US politics).

Or maybe someone else will recommend something. What part of the world do you
want maps of (it makes a big difference) ?

Now that is somewhat different. Many (probably all)
mapping/tracking/navigation apps will run offline (but perhaps with reduced
functionality). And all of them (as far as I know) will allow you to download
a fairly large amount of map data to the phone (word used deliberately since
that the important market as the app-vendors see it). However "phones" are
limited in storage, and some mapping data goes stale fairly fast, so most of
them (again, as far as I know) will only download somewhat limited data (maybe
a GB or two, max). I can't comment on /what/ data is included, since the only
apps I have use Google Maps data (shops, etc, are only available online as far
as I know), OSM (no data at all about shops etc), and the UK Ordinance Survey
maps (which are basically the 1:25000 maps of GB, and so include landscape
features but would scorn to include street names let alone shops). Other apps
are provided by what you might call "map vendors", where the app itself is
unimportant and its the actual map that you're buying. I haven't used any of
those, but it sounds as if they would be more what you are looking for. I
imagine that all of them can be used offline, but I also imagine that all of
them will have reduced functionality in that mode.

I haven't been following the thread closely so maybe this isn't what
you want. But my phone came with a widget bar that has buttons to turn
on and off WiFi, Bluetooth, GPS, background app data access, and a
brightness level adjust. I leave GPS turned off most of the time for
battery savings. If I use an app that needs it, the app complains and
I just hit the button and turn GPS on for the time I need it. If your
phone/tablet doesn't have such a widget I imagine you could find
something similar in an app store.

I *believe* that the "let google know" is an attribute of the
operating system and not of a specific App. I think that in order for
you to activate the GPS you are going to have to let Google collect
the data regardless of which App you use. I presently use OsmAnd which
allows me to download the maps for four countries and can turn the GPS
on and off.... but only if you have the selection "let google..."
ticked.

You do know I hope, that the Cellular phone system, in order to
function must know what phones are in which cell at all times, so your
whereabouts, or more accurately, your telephones whereabouts, is know
to the cellular system at any time the phone is turned on.

As far as I can see, that is not true in general. I can turn off the Google
location reporting (and history), but leave "Location" active for such apps as
want it -- and they all (of the several I've tried) seem to work perfectly[*].
GPS can be turned on and off, etc.

Actually, on the devices I tested, there's no obvious independent control of
GPS as such, only for turning "Location" on or off. But, by drilling down,
there's an option to control how "Location" is implemented -- which in effect
means that I can turn off GPS without turning off, say, WiFI-based Location.
Also, every time I change the main "Location" settings I get prompted with that
damned "Allow location data to be sent to Google?" prompt -- I just swear and
say no (again). Seems to work.

I speculate about why this works for me but not for you:

I seem to remember you saying that you on 4.2 ??? -- anyway, there are hints in
the Google documentation (can't find anything solid, I'm afraid) that some of
the location settings have changed in 4.4. It /seems/ to be saying that there
used to be an "Access Location" setting (presumably misnamed) that has since
gone away.

It may be that OsmAnd acts differently from the apps I tried, and maybe doesn't
get the permissions thing quite right.

There seem to be two levels of "Location" services in Android. There's a
low-level one, which I assume is the one that the apps I have on /my/ devices
are using, because the other doesn't supply data that they display. And there's
a higher-level one (that can tell you, say, where you've been, or whether
you're riding a bicycle!), and I speculate that maybe OsmAnd uses the latter
(at least some of it, and maybe in tandem with the lower-level one) and that
that /does/ requires the "Send location data to Google" permission (since it's
part of Google Play Services).

-- chris

[*] Including, I'm pleased to say Google Maps which can show my current
position on the map without requiring the "Send location data to Google"
permission -- whether that really means that it isn't sending the data to
Google is beyond my current ability to check...

I've got that and really like it (it saves maps etc. to the external sd
card), but I can't get it to forget that I once plotted a trip to Utah.
No matter how many times I tell it to Clear Destination it refuses.
I've only saved 5 'favorites', and the distances to my 'favorites' bear
no relationship to anything reasonable. I've tried to set different
destinations, but the Utah destination sticks.

Annoying and useless.

Duh. It seems to lose its mind when it's not in contact with any
satellites, but when it gets a fix stuff looks reasonable.

Never mind.

Again based on memory which is getting somewhat problematic, I think
you have to go to the actual trips saved and delete them individually.
At least I remember having a bunch of bike way points listed and it
took me a while to locate where they were saved to and to get rid of
them. It was accomplished from within OsmAnd though not by deleting
files with a file manager.

Hmmm... I was wrong and you are correct. I was confusing the "tell me

It behaves badly when it's not in contact with any satellites, but when
it gets a fix it works the way you'd expect. Too bad it's such a bitch
to actually READ the damn thing outside :-(

Only to the nearest cell (and even that can be distorted by buildings

The way Android works at this point, in general, is that apps are typically
coded to 'Play Services'. This was Google's answer to the fragmentation
problem - and why OS version is generally less of an issue for most apps.
Play Services is what (for the most part) handles running downloads apps by
providing APIs to developers. Resultantly, Play Services gets basically all
of the data your phone generates from the GPS receiver. You have to allow
Google to access that data, because, well, that's what Play Services does.

I've been happy with the $7 CoPilot navigation app for similar reasons - it
lets me download map data when I'm on WiFi, and doesn't require a pervasive
data connection during actual navigation. The only weird thing about it is
that it "drills down" when entering addresses, so you start with the
city/state, then add a street name, then a house number, which is a bit
backwards...though you can paste a full address from the clipboard, and if an
address is clicked from a text message or website, Copilot is an available
handler.
