[@renatoarg]

hi @CodingWithMitch congrats for the great video. Please do you have any example testing UIs?

[@grooss4002]

Thanks, very helpful video! Is there a way to mock a ViewModel in a fragment test or how should i test it?

[@mehdiparsaei1867]

Thanks a lot, my teacher!
I could get the MainFragment without a factory.

[@Mandoo145]

Thanks, you are a lifesaver!

[@genesiscatano]

24:18 "android:exported" is required to be included in everywhere you use "intent-filter" after the SDK version 31. If you want your app to share intents from one specific class you should make it true, if not then false.

[@Vemu]

Can you make a video about package installer? No one has done video about that yet

[@David-xy4nw]

even though I do not know anything about the android development, I still watch your videos, because I really enjoy the way you explain things. Would be really cool if you could make a react-native course

[@codingwithmitch]

Maybe in the future who knows. I think react native is a better choice than flutter personally because JavaScript jobs are so easy to come by. It gives you more employment options

Tks for #Hilt 👍

[@ALIRAZA-hz1db]

Hii hope you are doing well. I saw your old video on caching with retrofit. I have a question that how we can load data from cache first then from network if the Internet is available.

Well, I wasted a bunch of time trying to get this to work for my unit tests yesterday guess I should have seen this video!
hahaha oh well.
Thank man

[@sfk1991]

Hey Mitch , for someone who just have started about dependency injection do you recommend I pick up hilt over plain dagger?

[@codingwithmitch]

Yeah its way easier. Dagger is good to know but learning curve is rough

[@codinginflow]

Normal Dagger is only for people with 200 IQ

[@sfk1991]

@@codinginflow Having followed your great tutorial on dagger a couple months ago I laughed harder than I should on this comment.

How are you 🥰

[@codingwithmitch]

good

[@mehdiparsaei1867]

Why don't we do a full UI test instead of Unit and Integration tests?
I mean by ignoring the UI test time, UI tests can test everything in the real world.
Who agrees with me?
