Ti.App.addEventListener('resume', function () {
        handleURL(Ti.App.getArguments().url);
});

It will pass an empty url. Use "resumed" event instead.
I tried it and it worked.

Can't make it work on android... how I launch my app from another app?
I'm trying to launch as

var didItWork = Ti.Platform.openURL('feedback://estabelecimento?id_empresa=1');
    if(!didItWork) {
        alert('You need to install the Target app');
    }

but I always get that this app is not installed... and on my tiapp.xml on android's section I have this:

<android xmlns:android="http://schemas.android.com/apk/res/android">
        <manifest>
            <uses-sdk android:minSdkVersion="21"/>
            <uses-permission android:name="android.permission.INTERNET"/>

            <activity android:name=".FeedbackActivity" 
                android:label="Feedback Brasil" 
                android:theme="@style/Theme.Titanium" 
                android:configChanges="keyboardHidden|orientation|screenSize"
                android:alwaysRetainTaskState="true">

                <intent-filter>
                    <action android:name="android.intent.action.MAIN"/>
                    <category android:name="android.intent.category.LAUNCHER"/>
                </intent-filter>

                <intent-filter>
                    <data android:scheme="feedback" android:host="" />
                    <action android:name="android.intent.action.VIEW"/>
                    <category android:name="android.intent.category.DEFAULT"/>
                    <category android:name="android.intent.category.BROWSABLE"/>
                </intent-filter>
            </activity>
        </manifest>
    </android>

what i'm doing wrong?

Thanks

@FokkeZB I followed the steps and it works well for iphone and for android, it launches app and shows passed url first time only.
If the app is in background mode then it shows blank screen.
Do you have work around for this issue?

@DouglasHennrich @mitulbhalia opening a Titanium Android app from an URL has had (and probably still has) lots of issues and edge cases. See https://jira.appcelerator.org/browse/TIMOB-20490

@FokkeZB
The above was working fine till now but i need to change the urlscheme for ios something like https://www.url.com/param/?view=123
so i tried to set CFBundleURLSchemes to https://www.url.com and www.url.com but did not work.
should i need to use something else for CFBundleURLSchemes?

@mitulbhalia I have no idea, sorry. I haven't been using Titanium for 2 years anymore. I'd suggest to try TiSlack.org
