Menu
I have web page where I have Button that either opens app (if it installed) or directs to App store if app isn't installed. It all works if App is installed (I call into "MYAPP://"). However, if app is not installed Safari shows error message "Can not open URL" and that's it. Is there way to disable that message from JScript or is there another way to find out from JScript if app installed (instead of hitting app URL)?
To MODERATOR: I saw someone asked similar question and Moderator wrongly marked it as duplicate. Please understand that question was specifically about doing it from Browser.
Found somewhat suitable solution here
BTW if someone interested in how to do same thing for Android, here is code. We are using Dojo library:
dojo.io.iframe.send({
url: "yourApp://foo/bar",
load: function(resp) {
// nothing to do since it will automagically open App
},
error: function () {
window.location = "go to Android market";
}
});

Your website can check if your Android app is installed.
In App store, click on the user icon top right of screen. Select "Purchased", then ensure that "All" is selected. Scroll down that list - Apps will either have an "Open" button (if they are installed), or a cloud download icon if they are int installed but eligible to be installed on that device.
Yes, safari will detect the *. ipa and will try to install it, but the ipa needs to be correctly sign and only allowed devices would be able to install it.
At Branch we use a form of the code below--note that the iframe works on more browsers. Simply substitute in your app's URI and your App Store link. By the way, using the iframe silences the error if they don't have the app installed. It's great!
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript">
window.onload = function() {
// Deep link to your app goes here
document.getElementById("l").src = "my_app://";
setTimeout(function() {
// Link to the App Store should go here -- only fires if deep link fails
window.location = "https://itunes.apple.com/us/app/my.app/id123456789?ls=1&mt=8";
}, 500);
};
</script>
<iframe id="l" width="1" height="1" style="visibility:hidden"></iframe>
</body>
</html>
If others have better solutions to detect whether the URI scheme call actually failed, please post! I haven't seen one, and I've spent a ton of time looking. All existing solutions just rely on the user still being on the page and the setTimeout firing.

here is a code that works on iOs, even if the "Can not open URL" still show.
window.location = "yourApp://foo/bar";
clickedAt = +new Date;
setTimeout(function() {
if (+new Date - clickedAt < 2000) {
window.location = "go to Android market";
}
}, 500);
Thanks for the android solution.
