Hey collins, apologies for late reply. Where you able to figure it out?
Make sure to download and install Android Studio first.
Here is where you select the titlebar and click on 'delete' - keep in mind this will remove the Share functionality.
Next, Run the App, you will get an error. There will be a screen that pops up (sorry dunno how to get there otherwise) that will show you code.
You will need to remove these lines:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
Then run again.
