Hi @thiendn160794, thank you for submitting assignment 2 .

Overall

• The apps run fine without any serious crashing.

Great stuffs

• Nice using RecyclerView for listing items.
• Nice using Retrofit for accessing New York Time API.
• Good job on using Glide for images .
• Great job on keeping things separate in each package, and code looks really clean. I like that

Area to Improve

• There are a lot of optional stories, you should do it. Because it will make you get better at programming android.
• You should setAdapter only once and then if there is new data, you just have to notify. So as to improve app performance
• You should define private for variables. It's a good practice. Here is why
• You should use Data Binding or ButterKnife for binding views. For an example :

rvArticle = (RecyclerView) findViewById(R.id.rvArticle);
pbLoading = (ProgressBar) findViewById(R.id.pbLoading);

• UI looks simple you should pay more attention to it. You can take a look at Phong's assignment Link
