Go to the documentation to learn how to Fix dependency resolution errors.

here is the dependencies im using for this project. hope you can solve this please.... DEPECDENCY :

dependencies {

    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.1'

    // Room Components
    implementation 'androidx.room:room-runtime:2.4.0-beta01'
    implementation 'androidx.room:room-compiler:2.4.0-beta01'
    implementation 'androidx.room:room-testing:2.4.0-beta01'

    // Lifecycle Components
    implementation 'androidx.lifecycle:lifecycle-viewmodel:2.4.0'
    implementation 'androidx.lifecycle:lifecycle-livedata:2.4.0'
    implementation 'androidx.lifecycle:lifecycle-common-java8:2.4.0'

    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

Can you post your related gradle files? It might be a mix up of using api vs implementation for dependencies. — avalerio

Looking at your gradle file the dependency

implementation 'androidx.room:room-compiler:2.4.0-beta01'

needs to be

annotationProcessor 'androidx.room:room-compiler:2.4.0-beta01'

Here is the support documents for room.

https://developer.android.com/jetpack/androidx/releases/room

As a side note I would avoid using a beta version unless you are truly dependent on a new feature that was added or a bug fix.
