and the codes is all HERE in public gist github
All I realize is from this forum, I check the generated and still not the same in the example, this is from my Reference and here's mine, Database_Impl not generated
My tries:
- Using kapt and yes I use the
id 'kotlin-kapt'for plugin or the same withapply plugin: 'kotlin-kapt' - ChatGPT asked me to remove
.allowMainThreadQueries()in StockQuantityRoom, still the same - ChatGPT also recommended me to put the annotation
@JvmStaticabovefun getDatabase, Still no clue - Commented the
@WorkerThreadin StockQuantityRepository but to no avail - Use the same version as the reference (https://developer.android.com/codelabs/android-room-with-a-view-kotlin) but no progress
- I double-triple check everything like names, var, and I all wrote there and the error still persist
- Every time I tried, I always Clean project and Rebuild project
- Invalidate Caches every time if there's no progress with Clean project and Rebuild project
- Create everything from start again based on Reference and my database still error with the same code as above as this is my third attempt.
- add
implementation "androidx.room:room-runtime:$rootProject.roomVersion"in the gradle, still error - open the IDE in administrator mode, clean and rebuild, still the same
- I add
(Dispatchers.IO)afterscope.launchinStockQuantityRoom.ktin my Gist(https://gist.github.com/KeiLazu/10540d564a51f574e0de2ccf1223311d) but still the error doesn't go away
Thank you in advance
