Is there a way to detect if an app is installed (URL Scheme)

Hey guys,

I need to open facebook app and skype app through my app, but if the user doesn’t have those apps(skype and facebook), i want to send him to appStore. In objective c i know there is a function “canDetectUrl”, wich verify if the url scheme is reachable, there is any way to do this with corona?

Thanks in advance

What if you try to open the url system.openURL(“skype:”) and if it throws an is.Error then open the app link in appStore system.openURL(“http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id="..SKYPE_APPSTORE_ID.."&mt=8”)

Ansca have implemented that URL schema partially, I have been asking for it over than a year and a half and all it takes it wrapping a plain API or allowing deves to create their own Plug-Ins like Gideros does…

apparently, we are at their mercy on how things proceed… [import]uid: 3826 topic_id: 21501 reply_id: 85080[/import]

That might be a solutions for the question at hand (I did not try that) The reason that I wanted this URL API is for some really cool stuff that you can do and Apple Approves of it too. So if Ansca play the *Apple* card, just saying… [import]uid: 3826 topic_id: 21501 reply_id: 85081[/import]

hi lano78, thanks for your response.

we couldn’t find that is.Error you’re talking about… How do I reach it? is it an event called “is” with the property “Error”?

We found that system.openURL() returns true/false, contrary to what is stated in the api reference, so what we can do is check for this boolean and if/then/else it.

Our frustration with Corona’s docs grows each day. We simply cannot trust it and have to second guess every bit of it and google everything… :frowning: [import]uid: 79152 topic_id: 21501 reply_id: 85271[/import]

also, your link doesn’t seem to work on the browser…
we are planning to use http://itunes.apple.com/br/app/skype/id304878510?mt=8 instead, why is your link different and why do you choose to use it that way? [import]uid: 79152 topic_id: 21501 reply_id: 85273[/import]

I want to do this as well, as we have a few apps out there and I want to be able to detect if a user has the other ones installed.

Would this be a case of setting a custom url scheme for each app and then trying to call a url for that app and testing the result? [import]uid: 91921 topic_id: 21501 reply_id: 92113[/import]
