Question

Tried to use room api and had to deal with asynchronous tasks you know why.
I chose kotlin coroutines and androidx.lifecycle. Tried to write some code and got 2 errors displaying in IDE
Cannot access 'kotlinx.coroutines.CoroutineScope' which is a supertype of 'androidx.lifecycle.LifecycleCoroutineScope'. Check your module classpath for missing or conflicting dependencies
Cannot access class 'kotlinx.coroutines.Job'. Check your module classpath for missing or conflicting dependencies
error
Here is my gradle module
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-kapt'
}
android {
compileSdk 31
defaultConfig {
applicationId "com.jacksafblaze.sqlitedemo"
minSdk 21
targetSdk 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildFeatures{
viewBinding true

minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

}
compileOptions {

}
kotlinOptions {

}
}

}
and gradle project
buildscript {

}
dependencies {
classpath "com.android.tools.build:gradle:7.0.3"

// NOTE: Do not place your application dependencies here; they belong

}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
I tried to invalidate caches and restart, to recreate app from scratch, and to reinstall android studio and I am still getting this error.

Answer 1

upgraded 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.5.0' to
'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.6.0-RC' and everything works fine

Answer 2

I have the same problem, if I manually add imports in the class the project will compile but the IDE will still display an error.
If you don't want to wait coroutines-android 1.6 release manually adding the import is a workaround, but you will have no autocompletion.
Android Studio build without autocompletion example
You could also have some problems with room, moshi and all libraries that use kapt, you can try to update to latest release (beta/RC) to see if the problem will be fixed in new releases.
For example, when I am writing this lines, moshi is not compatible with kotlin 1.6 yet, and a fix is planed to be released as soon as possible, see here for details.
