Logging for mobile simulator on iOS?

[Alan Stenhouse via use-livecode]

Asked this on the forums with no response, so trying here...:

Opening the "System Log" from the Debug menu in the mobile simulator opens the 
system log but it doesn't seem like any of our usual log messages appear there 
now. 

I think this changed some time ago but don't remember what (if any) the 
solution is. Can someone help? Thanks in advance!

cheers,

Alan

you are interested in wrapping with LCB in order to make it available to
LiveCode?

If so, let me know in a response to this thread and I can take a look at it
before the workshop to see if I can include it.

Re: load app to ios device for testing??

[Alan Stenhouse via use-livecode]

Hi Scott

Yes, I believe everything is configured correctly. I've been building + testing 
apps with LC Indy for mobile for many years and it's only relatively recently 
(last n months) that I've been having these problems. I can still test on the 
simulators but my iPhone doesn't appear in the Test Target menu when it's 
connected.

iTunes doesn't appear to support uploading of apps directly to the device any 
more, AFAICS. Is there some other manual way of installing a test/dev app to a 
device?

Hmm, wonder if it's just that my version of iOS is a little dated?  No, have 
upgraded and still doesn't appear.

My Xcode versions used are 9.2 and 10.1 with available SDKs being 11.2 and 12.1.

Now running ios 12.4 on my device, though was running 10.xx until yesterday 
(when I started this reply).

Any ideas? What other settings might affect this?

cheers

Alan

Hi Panos

Thanks for clarifying this. Now I'm wondering when exactly this changed as it 
definitely used to work in the Indy edition.

On the brights side, thanks to you (+ Scott), I won't have to try Scott's 4th 
suggestion as to which color chicken to sacrifice...! :-)

I am using mobilePickPhoto to take a photo.  On all Apple devices it's working 
great. It's also working as expected on all Android devices except a Galaxy 
Note 8.  On this specific device the camera comes up, we take the photo and 
hear the shutter sound, but no photo is returned/created.  It's as if 
mobilePickPhoto was never called.  Again, this ONLY happens on a Galaxy Note 8. 
 Anyone have any insight to this?   Perhaps someone has a Galaxy Note 8 and can

Re: put img into img after import snapshot

Hi Dan

Try putting a wait 50 millisecs (more or less?) after the import - pretty sure 
that's what I ended up with on mobile for the same issue. Not sure if it'd be

Re: Problem simulating a location

IIRC, mobileSensorReading() returns an array so you need to check the keys of

Perhaps:

if tSensorData["latitude"] is empty then

Re: Detecting full Mobile Sensor activation

[Alan Stenhouse via use-livecode]

Hi Graham

Some ideas, from experience:

1. Start your sensor on openStack or as soon as possible.

2. Ignore locationChanged messages with empty location or if "horizontal 
accuracy" is outside a threshold of x metres.

3. Just set a flag or other mechanism when you want to start and stop tracking 
which indicates to your locationChanged handler to record or stop recording the 
track.

Hopefully that sounds reasonable?

cheers

Re: Detecting full Mobile Sensor activation

[Alan Stenhouse via use-livecode]

Hi Graham

So, how do you define a "meaningful" GPS signal?

The GPS data you'll receive from locationChanged messages may have nothing for 
1-n messages at the start, followed by an increasingly accurate number of 
messages (as measured by the "horizontal accuracy" and/or "vertical accuracy" 
data items). The other apps will be utilising these to determine a "meaningful" 
signal. You can define that however you like, of course! :-)

Another thing you'll need to deal with is intermittent GPS signal which can 
happen for a number of reasons.

Anyway, good luck. LC can do the sensor stuff well I think, I'ill look forward 
to seeing what you come up with! 

cheers

Re: use-livecode Digest, Vol 200, Issue 5

[Alan Stenhouse via use-livecode]

Hi Graham

Have you tried it walking around outside in varying locations? Have you tried 
different devices and/or OS versions? You could try sharing it with a friend 
using Diawi or similar and see what they get.

Also try restarting your phone to see if that helps.

As you move around the countryside, you'll occasionally get some inaccurate 
reading (depending on surroundings) so you may decide it's best to store, but 
ignore, occasional inaccuracies and just use some form of interpolation.

Looking forward to even better location data in the future - it's constantly 
improving and most new phones will give you 3-5m accuracy in the right 
conditions. Perhaps the newest phones are already even better?

Here are a few links with more info:

"assessment of the gps accuracy of mobile devices":
http://blog.cartong.org/wordpress/wp-content/uploads/2019/03/Assessment_GPS_Accuracy_Mobile_Devices.pdf

"Smartphone GPS accuracy study in an urban environment":
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0219890

"Why GPS makes distances bigger than they are":
https://www.tandfonline.com/doi/full/10.1080/13658816.2015.1086924

though those may not be immediately helpful to you. :-)

Will look forward to hearing what you come up with!

Good luck!

cheers

Alan

LC9.6 Android EXIF image data issue

[Alan Stenhouse via use-livecode]

There seems to be an issue with getting EXIF data from images using 
mobilePickPhoto on Android (well, at least new Samsung mobile phones).

I *think* this is a new bug with LC 9.6, but as I don't have a relevant phone 
to test with, it's sorta difficult to check further. Particularly as we 
couldn't even use mobilePickPhoto on these phones prior to 9.6!

Has anyone else seen this at all? If it's a new issue then it'd be great to get 
it resolved in the 9.6 cycle.

Thanks for the info, though that is bad news. It had previously come through on

Thanks Mark and Monte for the info.

Had already stopped using the width/height specs and for photos from the 
library we had been getting EXIF info and still do in many cases (I think - 
more testing needed!), but as we can't do anything about what the OS gives us, 
I'll just slightly change the message for the user to inform them.

get URL results in tsneterr(6) on Android, previously worked ok

[Alan Stenhouse via use-livecode]

Hi all

Am re-building an app that's been running fine for over 2 years now and when 
attempting to get a URL I always get the error "tsneterr: (6)" contained in it 
with "could not resolve host" as the result.

When I try the same code in the IDE it works as expected.

I didn't previously include tsnet in my builds and I get this error whether I 
do or do not include it in my build for Android now. 

I do have "internet" selected in Application Permissions in the Standalone 
Settings.

I also build up my httpHeaders manually to include username & pw and these are 
still valid.

I recall previous discussions that were maybe similar to this issue but 
couldn't find anything in the forums/google/etc so far.

Any hints or other pointers welcome - thanks!

The code is:
---
put "https://" into tPost
put "Authorization: Basic" &"userName: " & CR & 
"password: " into tHeaders
set the httpHeaders to tHeaders
get URL (tPost)
---

cheers

Re: Ideas on iOS GPS tracking needed

[Alan Stenhouse via use-livecode]

Hi Graham

Are you checking the horizontal accuracy of each reading? (It's part of the 
array of data with your lat-longs, as well as speed, etc - though not on every 
phone). 

If not, try that and see if the anomalous readings are hugely out. From my 
experience, that's normally the case. If so, the easiest thing is to drop them 
in the short term, unless you get too many and then you may need to be a bit 
fancier. If you do, would love to hear the solution that you come up with.

HTH, cheers

Re: A question/survey of sorts for users of Navigator

[Alan Stenhouse via use-livecode]

Sounds interesting Geoff. The ability to customise your own actions on objects 
would be great - I think we all get annoyed with some of the clunkiness of 
repeated actions (and no doubt we don't use all the existing capabilities of 
LC..), so your addition to Navigator sounds very worthwhile!

cheers

Re: use-livecode Digest, Vol 222, Issue 27

[Alan Stenhouse via use-livecode]

Yes, you should textencode() to UTF when storing and textdecode() when reading 
- at least doing that on mobile worked for me.

Re: Audio Control on Mobile?

[Alan Stenhouse via use-livecode]

Hi Dan,

Check out mobilePlaySoundOnChannel in the dictionary and the related commands 
linked to it.

Don't think there's a player command for mobile, though I may have missed it...!

HTH

Re: Referencing Livecode

[Alan Stenhouse via use-livecode]

Hi David

In a couple of my publications, I described developing apps with Livecode and 
referred to www.livecode.org and www.livecode.com, but didn't include anything 
in the references as there was nothing (AFAICS at that time) that would satisfy 
scientific publication standards.

See: https://www.sciencedirect.com/science/article/pii/S2351989420309173
and
https://www.sciencedirect.com/science/article/pii/S2351989421001761

HTH

Re: Bard AI

[Alan Stenhouse via use-livecode]

Nice one. Great to see Bard in action.

Taking this as inspiration (and hoping this doesn't start Bard v chatGPT v ? 
wars), I asked chatGPT to "write me a sonnet about LiveCode".


Upon the canvas of the digital sphere,
LiveCode emerges, a beacon of grace,
Translating thoughts to scripts that endear,
Crafting software in a swift embrace.

With fluid tongue, it weaves its artful code,
In English syntax, clear and unconfined,
As programmers embark on quests untrod,
Their visions made real by this design.

This versatile tool doth span the seas,
>From Windows, Mac, to Linux it conveys,
To mobile realms, it leaps with greatest ease,
A bridge connecting worlds in countless ways.

So sing the praise of LiveCode, our guide,
Whose noble touch makes dreams a sweet, swift ride.


Bard-like indeed... :-)

cheers

Alan

Re: Workaround for regular Crash setting (audio) file of player?

[Alan Stenhouse via use-livecode]

Hi David

This rings a distant bell... not sure, but can you try

set the filename of me to empty
 
and then

set the filename of me to audioFile

to see if that makes a difference?

HTH, cheers

Re: Has anyone experimented with using Python within LC?

[Alan Stenhouse via use-livecode]

Hi Geoff

Sorry for not replying earlier but looks like you've got it sorted. I did a bit 
on this years ago and am contemplating it again. Just looked for my old stack 
and see this script for running a python script and putting the output into the 
"output" fld:


on runPythonScript pScript
   put the tempname &".py" into tFile
   put pScript into URL ("binfile:" & tFile)
   put shell("" && tFile) into fld "output"
end runPythonScript

Was starting to provide an interface for experiment parameters for the scripts 
I was running (for some Turi ML classifications) but the project paused...

cheers
Alan

:-) For example, interfacing to machine learning (& associated) libraries for 
creating + running ML models (in my test case).

Application disappears unexpectedly (goes into background)

[Alan Stenhouse via use-livecode]

I've got a MacOS LC standalone that opens a stackfile external to the 
application. Whenever I click inside one of the stack windows which doesn't 
have current focus, all the stack windows disappear and reappear only when I 
switch to another application and back again. Activating a stack window by 
clicking on the window title bar works normally (i.e. does not disappear).

Has anyone else seen this at all? Any suggestions for tracking possible causes?

MacOS Ventura
Laptop M1
LC 10 dp... and LC9.11


Thanks a lot for any pointers!

cheers
Alan

HI Jacqueline, thanks and sorry for the delay in responding... xmas etc!

Yes, there are no hide (nor set visible to false) of windows though there is of 
some controls. But not related to any relevant scripts.

Any other ideas? :-)
