Answer 1

There may be more than one reason. So, these are some instructions that you can follow:

1 - You may check if AndroidX is enabled. android/gradle.properties or .android/gradle.properties must contain as mentioned in here :

   android.useAndroidX=true
   android.enableJetifier=true

Here is the source.

2 - Check your build.gradle file. You may need to comment androidTestImplementation . Here is the source.

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    // androidTestImplementation 'androidx.test.ext:junit:1.2.1' // <----- Commented this out
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.google.firebase:firebase-analytics:17.2.0'
}
