Google documentation says the following methods are available:
But neither my IDE is seeing them, nor the jar source has them.
This is what build.gradle has
implementation('com.google.firebase:firebase-admin:9.2.0') {
exclude group: 'commons-logging', module: 'commons-logging'
}
Any clue on what I'm missing?


The documentation you linked is for the SDK for client-side Android code, but you're actually including the Admin SDK for use in trusted environments. The documentation for the SDK you include can be found here.
