[🐛] [ANDROID] Duplicate class com.google.firebase.Timestamp

[mikehardy]

There is no reason to have direct firebase dependencies in your app level build.gradle, and certainly not with outdated versions.

Auto linking will bring those dependencies in for you from the react-native-firebase modules.

If you must depend on them directly for some project-specific reason (like you have custom native code on Android that uses firebase native apis directly...), remove the bom one, just depend on the specific modules you need and do not specify a version

[sridixteam]

just check your project level build.gradle file and remove extra thing which on is not used...

my android/build.gradle file souce code..........******************

buildscript {
ext {
buildToolsVersion = "33.0.0"
minSdkVersion = 21
compileSdkVersion = 33
targetSdkVersion = 33
kotlinVersion = "1.8.0"
// googlePlayServicesVersion = "+"
// firebaseMessagingVersion = "+"
// We use NDK 23 which has both M1 support and is the side-by-side NDK version from AGP.
ndkVersion = "23.1.7779620"
}
repositories {
google()
mavenCentral()

    maven { url 'https://maven.google.com' }
    maven { url "https://www.jitpack.io" }
}
dependencies {
    classpath("com.android.tools.build:gradle:7.3.1")
    classpath("com.facebook.react:react-native-gradle-plugin")
    classpath('com.google.gms:google-services:4.3.15')
}

}

and android/app/build.gradle file like this......***************

apply plugin: "com.android.application"
apply plugin: "com.facebook.react"

facing same issue..
did you find any solution @ailtonaires

I removed the line below and it worked for me:

//firebaseMessagingVersion = "+"

and android/app/build.gradle. remove :+ implementation "com.facebook.react:react-native:+" => implementation "com.facebook.react:react-native" work for me 🙏
