Google services plugin v4.3.9 has this bug. A newer plugin version is available with the fix. Please manually upgrade classpath 'com.google.gms:google-services:4.3.9' to classpath 'com.google.gms:google-services:4.3.10' in your project-level build.gradle file.
i think still have bug 4.3.8, 4.3.9 , 4.3.10.
recommend downgrade 4.3.7

It is an error with the AGP. Change the minSDKVersion to 24 for now
As described in the documentation:
If you are using Android Studio Bumblebee Canary 4 or AGP 7.1.0-alpha04/7.1.0-alpha05, you may hit the following crash:
java.lang.AbstractMethodError: abstract method "void androidx.lifecycle.DefaultLifecycleObserver.onCreate(androidx.lifecycle.LifecycleOwner)"
To fix, temporarily increase your minSdkVersion to 24+ in your build.gradle file. This issue will be fixed in the next version of Android Studio Bumblebee and AGP 7.1.

I am using Kotlin for my android app. I am unable to finish my Gradle Build due to this error :
Failed to resolve: com.google.firebase:firebase-core-ktx:
I tried all possible solutions available on stackoverflow. I have already downloaded the latest google play services from the SDK manager. I placed maven{url...} in my all repositories, yet can't fix this error. Even tried adding version specification in my implementations. Please help me with this!!
This below is my build.gradle file :-
buildscript {
ext.kotlin_version = "1.4.21"
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.1.1"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven { url "https://maven.google.com" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
These are the dependencies added to the code :-
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.3.2'
implementation 'androidx.appcompat:appcompat:1.2.0'

testImplementation 'junit:junit:4.13.1'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

Try this:
implementation 'com.google.firebase:firebase-core:16.0.1'
Also you can try this, if you are using the bom library.
implementation 'com.google.firebase:firebase-core'

I've been struggling with this issue for a long time so I decided to ask you.
I'm developing a chat app and for push notifications I'm using Firebase Functions. I'm getting always the data from onMessageReceived twice. For some people the solution was removing de gcm dependencies and use only the firebase ones but i think is not my case. Anyway I'm showing you all the code:
This is my index.js:
exports.notifications = functions.database.ref('chats/{chatUid}/messages/{pushId}').onWrite( (change, context) => {
var valueObject = change.after.val();
var chatUid = change.after.ref.parent.parent.key;
var data = {
'data' : {
'conversation_id' : chatUid,
'message_key' : change.after.key,
'message_title' : valueObject.title,
'message_body' : valueObject.message,
'userFrom' : valueObject.userFrom.toString()
}
};
const options = {
priority: "high",
timeToLive: 60 * 60 * 24
};
return admin.messaging().sendToTopic(chatUid, data, options)
});

Thank you for your time :D
I'm stupid.
It was my fault in android code, nothing to do with firebase functions:
I was using onWrite(index.js) and in my android code I was writting twice in firebase database, one for writing the message_key(push()) and other for setting the properties(setValue()):
finalReference.push().apply {
val map2 = HashMap<String, Any?>()
val dateFormat = SimpleDateFormat(DATE_FORMAT, Locale.getDefault())
dateFormat.timeZone = TimeZone.getTimeZone("UTC")
map2[FB.DATE] = dateFormat.format(Date())
map2[FB.MESSAGE] = entryText.text.toString()
map2[FB.READ] = false
map2[FB.RECEIVED] = false
map2[FB.TITLE] = fbUser.displayName
map2[FB.USER_FROM] = fbUser.uid.toLong()
map2[FB.USER_TO] = conversation_data!!.users_id.find { it != fbUser.uid }?.toLong()
setValue(map2).addOnSuccessListener {
child(FB.RECEIVED).setValue(true)
}
entryText.setText("")
}
So the solution was to change onWrite for onCreate on index.js.
Hope it helps anybody.
