Retrofit Caching Example and Why it SUCKS

[@raghvendrasahu5596]

cache not store using POST method. HTTP 504 Unsatisfiable Request (only-if-cached) error

[@EklakDangaura]

Damn, this is fast. Just had a look at the repo this morning.. now the video. Thanks. :)

[@codingwithmitch]

I didn't think I'd do it until tomorrow, but I got inspired.

[@pradeepkumarreddykondreddy7048]

when max-stale value set to less than 1 day, caching is not working. Any reason for that ?

Hi Mitch, I have to cache aurora forecast data from services.swpc.noaa.gov which is 2MB in size. I managed to download, parse and save the data as a String to the Room Database, but if I try to select the data from the database I am told the data is too big. Do you have any suggestions how to handle this?

how to cancel a retrofit request used in executor , plz share video

[@ikhiloyaimokhai9974]

Really great tutorial and explanation. When Room is used for caching, how often would the data be refreshed from the network?

[@syyamnoor9792]

It doesn't suck, it's just the implementation that does. Why don't you use just hit one api to fetch all the data and store it in a list etc, and then cache it. For searching we can avoid using other api hits like photos/{id}, we can simply search from that cached list.

[@codingwithmitch]

its shit. You should cache with room

[@abuzarshaikh3596]

Great tutorial! cache can be modified or edited?

[@Hereisthething]

thanks for the video mitch and to clarify the retrofit cache is just in-memory right? i.e. if you kill the app and restart the app when you are offline, there is no cached data

[@codingwithmitch]

It's saved to a file. It persists if the app dies I believe.

You can't

Mitch can you make the tutorial on Store library for storing data

I cant force update new data, retrofit always caching I have tried with no cache and also force network. Thanks bro

Hi mitch how to use retrofit cache in this secenario? When we have internet save data in cache but dont use .But if we dont have internet we use cache .

[@codingwithmitch]

That's what it does by default

[@jawadahmed6190]

@@codingwithmitch Oh thanks. I didn't know that.

[@salmanhameed9495]

you didn't make serviceGenerator class' constructor private so, how it could be singleton ?

You got me

Very good job ! Thanks for the video !

Few years after and I used it, didn't understand why it should be so bad, if you cache it a db you also cache the whole response? My app loads a list from a rest api using retrofit, the caching works wonderfully, don't see the problem.

[@luiferadventures]

and what about Glide?

[@TBadalov]

This doesn't make retrofit caching any less. What you were describing are two different layers of caching. One can still use room to cache complex data structures which are still eventually retrieved via API call. One doesn't contradict another

I love your tutorial I'm learning java now just soon I'll be developer

teacher should i go for both mvp and mvvm or only one?

[@codingwithmitch]

Use one architecture per application IMO. But that is just my opinion. More than one would get confusing I think

[@muraddadasov8595]

@@codingwithmitch thank you much

[@JacobZinn-rs1we]

It's true... retrofit caching really does suck. I spent 4 hours on it and it never hit cache. I spent 1 hour on room and it works great!

we love you keep going.

You are right .. caching sucks .. mainly on server-side.. biggest pain is caching error . OMG

teacher. the thing that i didn't understand is maxStale. you assigned for 7 days. what happens after 7 days ?

[@highlightmatchoffootball4986]

thank you so muchhh

[@enricobrunodelzotto7486]

Setting a cache on the network layer it's ok, but what you're doing here is kind of an hack. Override headers with interceptors could be ok for a *fast* demo, but, all that part of logic should be done by the server. The caching at app level should be done with the repository pattern, in the higher level! So i really really no encourage people to follow the hack approach!

I said not to do this... This is how you should cache github.com/mitchtabian/Local-db-Cache-Retrofit-REST-API-MVVM
