Answer 1

You can get the all the installed applications like this..

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
    mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
    List<ResolveInfo> appData = packageManager.queryIntentActivities(
            mainIntent, 0);
    for (ResolveInfo appInfo : appData) {
        Application application = new Application();
        application.setApplicationName(appInfo.loadLabel(packageManager)
                .toString());
    }

The code that was written here is indeed a Java code. I don't think Titanium exposes a methods that access the information you are looking for.

What you can do is write your own native Titanium Module in Java that uses that uses the code kalyanpvs wrote you and use it from within javascript.

I'm guessing at your requirements slightly but it is possible to link a url to your app.

When you try and load that url from any source (eg an sms, an email) it will open the app if you have it, or else it will just open the url in your browser.

See here: Android Respond To URL in Intent

Does that help at all?
