@DatabaseView注释室数据库android

Question

I am using Room database android every thing work fine but @DatabaseView annotation can't be resolved (Giving Error) bellow are the dependencies

def room_version = "1.1.1"
    implementation "android.arch.persistence.room:runtime:$room_version"
    kapt "android.arch.persistence.room:compiler:$room_version"

Answer 1

Room version should be 2.1.0-alpha02 or greater

@DatabaseView is added in the room version 2.1.0-alpha02

Please check the release notes for more detail https://developer.android.com/jetpack/docs/release-notes

Also, it is available only on androidx

So change it to

def room_version = "2.1.0-alpha02"

implementation "androidx.room:room-runtime:runtime:$room_version"
kapt "androidx.room:room-compiler:$room_version"
