Provided error handling sample code doesn't seem to work for me with API 27 and AS 3.0+

This doesn't seem to work

Uri googlePlayUri = Uri.parse("market://search?q=map");
Intent googlePlayIntent = new Intent();
googlePlayIntent.putExtra(Intent.ACTION_VIEW, googlePlayUri);

if (googlePlayIntent.resolveActivity(getPackageManager()) == null) {
    Snackbar.make(mRootLayout, "Sorry, nothing found to handle this request.", Snackbar.LENGTH_LONG).show();
}
else {
    startActivity(googlePlayIntent);
}

I'm just getting another snackbar with the "Sorry..." message from the code above.

So, I modified the code like this

Uri googlePlayUri = Uri.parse("http://play.google.com/store/search?q=maps&c=apps");
Intent googlePlayIntent = new Intent(Intent.ACTION_VIEW);
googlePlayIntent.setData(googlePlayUri);

if (googlePlayIntent.resolveActivity(getPackageManager()) == null) {
    Snackbar.make(rootLayout, "Sorry, nothing found to handle this request.", Snackbar.LENGTH_LONG).show();
    }
else {
    startActivity(googlePlayIntent);
}

One of the reasons was changing the way implicit intent is created, so instead of using an empty constructor and putting an Extra with the action and uri, I did it the same way as was described in the course with the previous intent. Add the intent action in the constructor, and add the Uri with setData instead of putExtra.

The other issue was that even after doing the above, I still couldn't get it to work using the "market://..." version of the Uri (maybe because the emulator doesn't have google play?). So I had to change the Uri to a classic browser version "http://..." and then it worked (with the google maps app still disabled of course), it opened the default browser with map applications from the google play store.

Just letting everyone know if they try using the sample code and stumble upon these issues. And maybe Ben Jakuben can update the code in the teacher's notes as well :).
