Android Jetpack: Room

Florina Muntenescu introduces Room, the database persistence library for Jetpack. Room allows you to:
* write less boilerplate code
* map query results to objects automatically
* provide compile-time checked queries
* test database operations, including migrations, more easily
* avoid performing any database operations on the main thread

Take a look at the resources below for more information!

I am so excited to see the test support, especially the migration test. Great video.

[HtopSkills]

Any official programming language for Android (Including Java) deserve a video like this

Every house should have a "Room"

The really tricky part is when you want to use on your custom objects and relationships.

Where has version 2.0 been published? The Google Maven repository only lists androidx.room 2.0.0-alpha1. Release notes are missing, too.

[AmitJayant]

This is all great. But why there is no guide/documentation on it on Android Developers website?

[Triviorito]

There is typo:
The method It's not called but

Without an S in Migration

Florina, should I use intelliJ or android sdk if am using kotlin for android development?

[vladislavsyrgashev]

Hi Florina!!! As i see You are a pretty good at Room stuff in the whole world. Could you please help me understand one aspect of it. I am new at programming Android. So this is my kind of problem i got stuck with. I pretty much understand how this Room works. Anyway, I've got SQLite database file with 1000's of rows of data. And i want my project to fetch data from this .db file and populate RoomDatabase. But all solutions on Stackoverflow seem to fail. Can you show me the way to do it, please? Thank you.

java.lang.RuntimeException: cannot find implementation for database

Can you remake "Room with a View codelab" with Kotlin and Room 2.0 version

[Kolumbic]

Any chance to get code examples in Java?

[kristofferlund]

Got stuck on 2:27 because that transition was too awesome

[michealandretis]

You guys need to clarify your relationships documentation. It's misleading and barely comprehensible. Room is supposed to reduce "boilerplate code" but a single join query requires way too much complex code.

Hey Florina Muntenescu, Is there any possibility of creating and accessing database dynamically like Creating Duo, DTO, and Database with room dynamically

[Bithros]

How can i use a predifined sqlite.db with room? I have search the last hours but i can not find any solution. I think that this must be solved from google except if you already did it and i can not find it!

[progtom]

Happy days, no more huge classes of verbose SQLlite3 code

how to load and read external database(SDcard )？

[dumitru-qu]

Well, she's Romanian.. But however she's good on English, and you can easly understand, what does she wants to tell to us, and of course I have watched this video not for learning but to impress myself that she is a Romanian and she became a Android Developer and presentator of Google Developers, Yeah she's earning a lot, but i don't take care about it, i also want to become an Android Developer not for money, but to show to people that i can break the ice, i have only 12 years and still understanding this, but however i'm learning everyday a little bit, and with this tempo i will know perfectly java language for android. So if you are an android beginner developer, don't worry about this, everyone was like you when they wanted to start this, soo don't take the Android Studio yet, because it will be hard to understand for you, just go to your phone and download Sketchware from Google Play, (In case that you are a beginner) . In this app you will develop your app also like android studio, but there codes are blocks, and every specific block is an code, but is much easier to understand, soo guys please leave a like on this comment, i hope that i helped you, Thanks
