                                            .setProductId("product_id_example")
                                            .setProductType(BillingClient.ProductType.SUBS)
                                            .build())

    I run into the same problem. By hovering with the pointer over ‘ImmutableList’ I selected the entry Add dependency on com.google.firebase:firebase-crashlitics-builtools and import...

    This action created the following line in the import section of my activity file

    import com.google.firebase.crashlytics.buildtools.reloc.com.google.common.collect.ImmutableList;

    and the following line in the build.gradle file:

    implementation 'com.google.firebase:firebase-crashlytics-buildtools:2.7.1'

    However, the word reloc in the import line initially appeared in red color with the hint Cannot resolve symbol ‘reloc’. Then I noticed that in the build.gradle file, android studio was offering to change the version of the crashlytics-buildtools from 2.7.1 to 2.9.1. After doing so and syncing gradle, the word reloc was no longer red and ImmutableList was recognized correctly.

    I wonder whether it is really necessary to import the firebase crashlytics-buildtools for the integration of the Google Billing Library (I use it for an app with in-app purchases) or if there is a more simple way to do this.

    Android Studio suggests the firebase-crashlytics-buildtools dependency to import the ImmutableList class. Doing so resulted in a big increase of the file (bundle) size.

    Try instead including guava as a dependency, if you are not using crashlythics in your app:

    // graddle

    implementation ‘com.google.guava:guava:31.1-android’

    // java class/code

    import com.google.common.collect.ImmutableList;

    This has a much smaller impact on the file size. In my case, the bundle was 2MB compared to 10 MB if using crashlythics-buildtools.
