i have trouble in set up Room Database since yesterday. and now you save me life

[alexcooller]

Спасибо, отличный туториал !)
Thanks, great tutorial !)

[SpiritVector]

Super clear, I think the problem that I could of had was watching this before learning about the List Class and basic design patterns like the
Singleton. I am so glad I studied before watching this, this was good man keep it up! I will say though that you will probably often get people without any experience complaining, with that said I am sorry you have to deal wit that!

I Will say that I was a bit thrown off by the new technologies used outside of vanilla Java, like the database annotations; obviously because this is the first time I have ever used any dependencies outside of code I have made myself.

[muhdkhairulamirinum]

TQ. this tutorial is straight to the point.

[holyc]

You are so amazing man, much thanks for you work

[didiruna]

I cant make object of AppDatabase (17:50). AppDatabase is abstract class. Abstract class can't have object in Java.

[FarrukhSaliev]

Thank you so much. Very simple and good tutorial!

[lagramolahumanamusic]

Thanks, man. You're very skilled. It was easy to follow you. Thanks! But still problems with migrating to the non-deprecated Activity Results API. I tried to follow your advice to Gaurav Samar but, after finishing saving a user, it will not show the updated list... It only shows it if I restart the app

[rawat_ji]

sir eak cheec smaj ni ayi @Insert ki querry me User ke bad ... kyu use keya he ?

[ildaphonse]

thanks so much for the tutorial, i can't seem to understand databases properly enough to integrate it into my app. So i can't store buttons in a databse right? this is so tough.

[sensibleguy]

well, there is some issue currently,

AppDatabase_Impl does not exist

dunno whats wrong here, can you help with this

[manfrombritain]

cant get room to fucking work with a single table, there's always some weird ass fucking problem. by the time i've got it to stop trying to insert null into an int field, i might have made 10 databases that work in SQLite or whatever

[dikshakumari]

for the little improvement first tell your students what you gonna build and then try to clear things one by one what is the process of thinking then make question is USER... user in insert query part what to mean...
