Room migration blog by Florina was excellent, but glancing at the Migration Testing blog, it looked scary to me, until I saw this video. Turns out it wasn't scary at all and was very straight forward. Thank you for this video. 🙂

When using the Automigration feature, I often mess up my databases in a way, where my code can't comprehend the new data and crashes when fetching the Rows from the table. Until they make it even easier to migrate, I will continue modifying my tables manually with DB Browser :D

I just changed the Device from asio to SPDIF-out (soft blaster z) TNice tutorials improved the soft quality dramatically. I tNice tutorialnk tNice tutorials did the trick!

Thx for another great video Philipp! A quick short video about Moshi would be great. (also a long one can be great too cause it has too many features!)

[tinoutech]

I love your ULTIMATE guides, thank you very much.

Great video as always Phil. I dont know if its because video was created a year ago from today and things changed since then but at this moment room automigration supports adding a new table and there is no need to do manual migration for that. Please correct me if i m wrong

[osisuper]

This feels so good. Thank you Philipp.

It would be better to use the extension function ".use{}" instead of "apply" at 29:31

[zoltanbalazskozma]

Very well explained. Do you have any information about what thread are these migrations run in? I could not find any information about that.

[hossamqandel]

Thanks Philipp for this useful content and for simple explaining

[samsammaniamantap]

Now I know why my migration with a new table didn't work well. Thanks Phil

[vbcv]

what about backing up and restoring a database (export/import) what would the best way to do that ?

[Guilo]

Thanks a lot. this is exactly what I was looking for

[Lethans]

Very well explained, thanks for the video. The automigration would not work in case of having, already done, several manual migrations? or at least i would have to generate a JSON migration file for all the versions of the database.
