I am getting the below unresolved reference error while trying to build a new Android app using Jetpack Compose and Material3 components.
I have so far tried the below steps mentioned in this page:
- Updated dependency of android.material to 1.5.04 or later
- Ensured compileSDK is 31
- Ensure comilation with JAVA 8
- Used AppCompatActivity to extend my MainActivity
- Invalidated caches and restarted
My gradle code is below:
plugins {
id 'com.android.application'
id 'kotlin-android'
}
android {
compileSdk 31
defaultConfig {
applicationId "com.example.recoverme"
minSdk 21
targetSdk 31
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
vectorDrawables {
useSupportLibrary true
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}

CodePudding user response:
You are missing
implementation "androidx.compose.material3:material3:1.0.0-alpha02"
in your build.gradle.
