Build Fail with 'com.android.tools.r8.utils.AbortException: Error: Program type already present: com.google.firebase.FirebaseApp'

问题

Hello when i implementing

implementation 'com.google.firebase:firebase-admin:6.8.0'

I am getting the error like

Caused by: com.android.tools.r8.utils.AbortException: Error: Program type already present: com.google.firebase.FirebaseApp

I have tried the below steps

• Clear Project
• Invalid catch and restart
• Rebuild

But still getting same error. I i removed com.google.firebase:firebase-admin:6.8.0 then i work well without it.

Here my app/build.gradle

apply plugin: 'com.android.application'
apply plugin: 'realm-android'

task clean(type: Delete) {

Build and Support versions which i am using

build_versions.min_sdk = 21
build_versions.target_sdk = 28
build_versions.build_tools = "28.0.3"
versions.support = "28.0.0"

I have tried using multidix and also referred more links but still didnt get any solutions.

回答1:

The Firebase Admin SDK isn't supported for use in Android apps. It's intended for use in server applications.
