LiveCode Forums.

Hi Everyone

Could someone possibly shed light on this for me I am absolutely stumped.

Is there any reason why a command that calls an API would work in livecode, but not when tested on a connected android phone?

The phone is connected via usb.

It basically calls the API , converts the json response and puts it in a field.

I will upload the script etc... if needed, but just wondered if I was missing something obvious?

Kindest regards

Paul

Hi Paul,

what API are you talking about?

Do you have the internet permission selected in your standalone settings?

Hi everyone

In answer to a few of the questions:-

I couldn't find an internet permissions bit in the standalone settings, but there is a command on the page that checks for a connection ( below) and this works fine.

command checkInternetConnection

put url "http://www.google.com" into tURL

if tURL is empty then
answer "no internet connection found, please try again later"
else
answer "testing internet connection........connection established"
end if

end checkInternetConnection

-----------------------------------------------------------------------------------------

The API is world tides.info see some of the script below. It seems to stop when it trys to run 'command json'.

Any help would be fab.

kind regards

Paul

Hi Paul,

just to be sure, -> ttidal_request is declared as a local or global variable?

Hi Klaus

Sorry I just realized it would be better to post the whole page script-

(the request tide command returns for example - https://www.worldtides.info/api?datum=L ... 996f0645d4)

Thanks v much

What do you get when you use:
Answer the result
after you send something to an url?

I would try to put your whole or partly url url in a variable then post it: Now the result is empty or contains an error
Or the 'it' variable contains what you want or an error string from the website

Also i would start globals with g not a t, it may work but it's better to recoqnise when reading the script.

On the Android tab in the standalone setting, then in the right below corner is Internet Permission which you have to tick(maybe it was already ticked)

Maybe you need to set a http Header first when using the whole string as put URL "your whole websitestring with extra stuff" into tMydata, or something i don't know

Hey Paul,
I don't have any solution or advice for your problem per se like Klaus and sphere, but I do hope you will go back and edit your previous posts so that the code portions are put into code display mode, so that others (like me) who are reading the thread have it a tad easier.

Short runs of code like:
on mouseUp
answer "Hiya !"
end mouseUp

are easy to read inline, the long run multiple handler sets like this one above: ...are not only condensed in space, but far easier to copy and look at in an editor, or read in chunks. As a side benefit for readability even in the code box, the block is formatted in a way that easily simulates the original formatting of the editor as far as indentation goes, like so: Just a suggestion.

Tried with the same results as you over usb

Then made these changes

In Standalone Application Settings - Android
Make sure Internet is checked in Application Permissions

In Standalone Application Settings - General
Check Select inclusions for the standalone

In Standalone Application Settings - Inclusions
check
JSON library
URL parser
Internet
Answer Dialogue
Ask Dialogue

I then got this result
There seems to be a general problem with automatic inclusions missing out some functions.
