I'd like to ask if it's possible to migrate to androidx.databinding in AndroidStudio 3.0.
I don't want to upgrade to AndroidStudio 3.2 just yet, and it seems that I can only import android.databinding instead of the androidx version.

I have added this in my app gradle file:

kapt "androidx.databinding:databinding-compiler:3.2.0-alpha16"

Project gradle dependency:

classpath 'com.android.tools.build:gradle:3.1.0'

All the other androidx libraries I added on gradle can be imported in code, but not databinding. Has anyone here still using AndroidStudio 3.0 successfully used androidx.databinding?

Thanks.

UPDATE:

In the app build.gradle, I updated the dependency from -jre8 to -jdk8:

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"

This is the app build.gradle dependencies:

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation "androidx.appcompat:appcompat:$rootProject.supportLibVersion"

    implementation "com.google.android.material:material:$rootProject.supportLibVersion"



    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"



    implementation 'com.squareup.retrofit2:retrofit:2.1.0'

    implementation 'com.squareup.retrofit2:converter-gson:2.1.0'



    implementation 'com.github.bumptech.glide:glide:4.8.0'

    kapt 'com.github.bumptech.glide:compiler:4.8.0'



    implementation 'com.google.android.gms:play-services-maps:16.0.0'

    implementation 'com.google.android.gms:play-services-auth:16.0.1'



    // architecture components

    implementation "androidx.lifecycle:lifecycle-extensions:$rootProject.archLifecycleVersion"

    implementation "androidx.lifecycle:lifecycle-runtime:$rootProject.archLifecycleVersion"

    implementation "androidx.room:room-runtime:$rootProject.roomVersion"

    implementation "androidx.paging:paging-runtime:$rootProject.pagingVersion"

    kapt "androidx.lifecycle:lifecycle-compiler:$rootProject.archLifecycleVersion"

    kapt "androidx.room:room-compiler:$rootProject.roomVersion"



    kapt "androidx.databinding:databinding-compiler:3.2.1"



    testImplementation 'junit:junit:4.12'

}



configurations {

    all {

        exclude group: 'com.android.support'

        exclude module: 'httpclient'

        exclude module: 'commons-logging'

    }

}

And this is the project build.gradle versions:

ext {

    archLifecycleVersion = '2.0.0'

    roomVersion = '2.1.0-alpha02'

    pagingVersion = '2.1.0-beta01'



    supportLibVersion = '1.0.0'

}

I executed this to find out more about the issue on my project:

./gradlew :app:kaptDebugKotlin

and I got this error:

e: error: cannot access NonNull

  class file for android.support.annotation.NonNull not found

  Consult the following stack trace for details.

So it seems that the underlying sqlite library is still using android.support.annotation.NonNull. Any idea on how to solve this?

Thanks.
