Answer 1

Try to add guava dependency in the app level build.gradle file which makes the build tools to use the latest version of android compatible guava.

dependencies {

    implementation('com.google.firebase:firebase-messaging:17.3.4') {
        exclude group: 'com.google.guava'
    }

    api 'com.google.guava:guava:27.0-android'
}

Answer 2

in this case, it's not the dreaded guava - it just cannot be added into the classes.dex ...

since you have minSdkVersion 16 ...you need to add a dependency for the multidex library:

dependencies {
    // implementation "com.android.support:multidex:1.0.3"
    implementation "androidx.multidex:multidex:2.0.0"
}

this is because of the 64k limit:

Versions of the platform prior to Android 5.0 (API level 21) use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK.

any other issues with that build.gradle, just leave a comment below.

edit: to generally exclude guava-jdk5, which may come from some age-old library:

configurations.all() { configuration ->
    exclude group: "com.google.guava", module :"guava-jdk5"
}
