Hello mam, This videos was very informative.
ps : Would it be possible for you to make full fledged video tutorials for development of a app. Like a video series for a ToList application or any other app.
I feel that people look for a video series so that they have a application ready to put it in their resume or atleast have one application in their pocket.
once again, Thanks for these videos they are really helpful😊...

[bristolwebdesigner]

Hi Thanks for this - I did use my own names for Fragments but stuck to the rest. Go some errors on MainActivity
replaceFragment(new HomeFragment()); - problem "new HomeFragment()"
case R.id.home: - problem "R.id.Home" - same on all cases
replaceFragment(new HomeFragment()); - problem on "HomeFragment" - same on all cases
Finally, . fragmentTransaction.replace(R.id.frame_layout, fragment); - problem with ", fragment)"
NB. The quotes I have added, they are not in the code. Would send screen shot but cannot see a way. Please let me know what I did wrong. Thanks.
