I have php file which looks for userAgent string to reply with the correct Intent to start my application.
The php file is:
<SCRIPT language=javascript>
function redirectOnUserAgent() {
var params = {};
if (location.search) {
var parts = location.search.substring(1).split('?');
}
var mapping = {
// scheme : market://details?id=<package_name>
'android': 'intent://www.example.com/ag?' + parts + '#Intent;scheme=http;package=com.my.example;end',
...
}
var userAgent = navigator.userAgent.toLowerCase();
for (var dev in mapping) {
if (userAgent.search(dev) != -1) {
window.location = mapping[dev];
return;
}
}
//else redirect to another page, or nothing
window.location = 'http://my.example.com';
}
</SCRIPT>
<!DOCTYPE html>
<head>
<meta charset="UTF-8">
<title>Redirect to AG</title>
</head>
<BODY onload="redirectOnUserAgent();">
</BODY>
</html>
And this file is called from my.example.com/redirect_to_ag?siteId=xx&data=yy
Up to now, I was reading this url from a QRCode reader and so the reader gives me the url, I click on open, and then it automatically interprets the intent to start the application.
Now, I wanted to do the same from a NFC Tag and saw it doesn't work.
But in fact, when I manually enter the url in the Android Chrome url field, nothing happen.
And I don't know how to see what happens in Android Chrome.
When I connect Android Studio to the device, if I read the url from a QRCode reader I see the following messages:
02-10 13:06:46.959 32710-32710/? W/cr_Chrome: Bad URI 'intent://www.example.com/ag?siteId=xx&data=yy#Intent;scheme=http;package=com.my.example;end'

And then the application starts. Good!
BUT when I manually enter the url in the browser's address field, I can see:
02-10 13:11:43.635 5186-5186/? W/cr_Chrome: Bad URI 'intent://www.example.com/ag?siteId=xx&data=yy#Intent;scheme=http;package=com.my.example;end'

And nothing more happens.
So could you tell me what prevents Chrome to correctly interpret the intent when it's given from the same url input manually??
EDIT
I don't really know if it could help but when I use the QRCode Reader and use the Intent Intercept tool, when I click on Open the url in the reader, Intent Intercept give me the following infos
ACTION:
android.intent.action.VIEW
DATA:
http://my.example.com/redirect_to_ag?siteId=xx&data=yy
MIME:
null
URI:
intent://www.example.com/ag?siteId=xx&data=yy#Intent;scheme=http;launchFlags=0x13080000;end
FLAGS:
FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET
FLAG_ACTIVITY_FORWARD_RESULT
FLAG_ACTIVITY_PREVIOUS_IS_TOP
FLAG_ACTIVITY_RECEIVER_FOREGROUND
EXTRAS:
none
MATCHING ACTIVITIES:
Chrome (com.android.chrome - com.google.android.apps.chrome.Main)
Then, when I click on SEND EDITED CONTENT to Chrome, application starts.
Well, from my side I don't really know how it could help me....
Again, my problem is to understand why it doesn't happen anything when I manually enter the url in Chrome's address field.
