So, I've been trying for hours to make notification works but without success.
My goal is to send a notification from the Firebase console and receive it on the phone. This means that I should only add the library to my application and configure a project on Firebase.
In my app I'm already using firebase for storage, analytics and ads without problem.
I've followed the official tutorial and also this video
I've not added the service in the manifest because I don't need to do any particular message handling
This is my manifest:

adView.adSize = adSize
adView.adUnitId = AD_UNIT_ID

adView.loadAd(AdRequest.Builder().build())
}
}
On the firebase console I see this:
Note: I've tried crating a new app from scratch and to do the same operation and that it's working!
I got it working, but I don't know how... I'm thinking is Android Studio's fault.
I've done these steps
created a new project on firebase
downloaded and imported the new google-services.json
cleaned cache data and reinstalled the app on the emulator using the button Run 'app' from Android Studio
the app is still showing stuff from the old firebase application, like it's using the old google-services.json
deleted gradle's build folder from Android Studio
reinstalled the app as before using the old configuration
notifications are now working
WTF!??
I'm thinking that the problem was due to gralde/android studio.
I've lost like 5 hours on this... I love programming :) :)

I am trying to understand and use firebasefirestore from android studio with kotlin.
I have been following tutorials from the official docs, and from udemy and youtube. I do the exact same thing as shown, but still my collection is not created in the firestore console.
I want to add a collection to firestore from within android studio with kotlin.
To my understanding all my code is correct, I have internet permission, I have all the dependencies needed in my gradle files.
And my code for adding a collection to firebase is the exact same as given in the official docs.
Still no matter what I do, I can not create a collection from running my app.
I can create a firestore collection from within the firestore console without a problem.
My app runs and execute with out any errors (beside not creating the collection in firestore).
Here is my code

Creating a db
package eu.example.firestoretest
import android.util.Log
import androidx.compose.runtime.Composable
import com.google.firebase.firestore.ktx.firestore
import com.google.firebase.ktx.Firebase
#Composable
fun fireStoreTest(){
// Create a FirebaseFirestore object
val db = Firebase.firestore
// Pass data onto the firestore db, it must be of type hashmap
val user = hashMapOf(
"first" to "Ada",
"last" to "Lovelace",
"born" to 1815
)
// add the user data to the collection
db.collection("users")
.add(user)
.addOnSuccessListener {
Log.d("FB", "onCreate: ${it.id}")
}
.addOnFailureListener {
Log.d("FB", "onCreate: ${it}")
}
}
I then call the function fireStoreTest in my main function, but it doesn't work.
Is there someone who could explain in very simple terms what it is I am doing wrong ?

I was also having similar issue where I was not able to add collection on Firestore from Android Studio. What worked for me is setting the rules of Firestore to this :
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if
request.time < timestamp.date(2022, 5, 3);
}
}
}
Once I introduced dynamic feature modules into my app, I was able to successfully refactor feature one (orders), build and deploy. But on refactoring the second module, i.e moving files and resources to that module, I get this error on build:
Execution failed for task ':features:catalog:createDebugCompatibleScreenManifests'.
> Failed to calculate the value of task ':features:catalog:createDebugCompatibleScreenManifests' property 'applicationId'.
> Failed to query the value of property 'testedApplicationId'.
> Collection has more than one element.
I have tried the following fixes:
invalidate cache
reclone project
ensure all gradle files are identical (except for applicationId bit)
checked that there are no errors in the manifest files
confirmed that no two modules share the same application ID.
rebase the project to the last working commit.
Any pointers as to what is causing this build issue?
Other info: I'm using dependency injection with koin.

The issue ended up being a library I had imported.
The library had plugin apply plugin: 'com.android.application'
instead of
apply plugin: 'com.android.library'
As such, gradle build task was looking for applicationId and applicationName in the manifest, which was not there.
Oops, developer error.
For me it happened when adding a new dynamic feature module with multiple flavors.
I solved it by changing inside module.gradle:
implementation project(path: ':app', configuration: 'default')
into
implementation project(":app")
Then add flavors into module.gradle
flavorDimensions "app"
productFlavors {
flavor1 {}
flavor2 {}
flavor3 {}
}
Here is my final module.gradle
apply plugin: 'com.android.dynamic-feature'
android {
compileSdkVersion 29
buildToolsVersion '29.0.3'
defaultConfig {
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"

flavor1 {}
flavor2 {}
flavor3 {}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}

implementation project(":app")

Uninstall the application from emulator and then restart it
I'm a new Kotlin Programmer. I tried to change the app icon by deleting the ic_launcher.png files and replacing my own images. As i see that is ridiculous what i'm trying to do, i copied the "Main Activity.kt" and "main_activity.xml" files and created a new project. As i tried to copy the files into the new project, the program throws a lot of errors:
It didn't imported the "kotlinx" packet and didn't perceive the elements in the xml file. As i tried to create an another new project to try whether the problem is only for this project, i realized that Android Studio doesn't perceive the xml elements anymore.
Here are some important infos about my project:

I would be very happy if you could solve my problem.
Revised answer after the deprecation of view synthetics.
You're missing the kotlin-android-extensions plugin in your build.gradle. It's responsible for generating synthetic view references.
kotlin-android-extensions is now deprecated, so it is no longer included by default and should no longer be added to projects. You should use findViewById or View Binding.
You can make it work by doing the following, but I don't recommend adding and relying on a deprecated library. Add the line to your plugins block at the top:
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
}
In Android Studio 4.1.1, the following code is missing in build.gradle (module: yourAppName)
id 'kotlin-android-extensions'

You need to add this dependency:
implementation "com.github.parse-community.Parse-SDK-Android:parse:1.24.2"
There is a very simple app made by Kotlin, it can work well under Android 8.0, Android 6.0 and Android 5.1 in Android Studio 3.0
but I get the error message "java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{info.dodata.mirror/ui.UIMain}: java.lang.ClassNotFoundException: ui.UIMain" when I run the app under Android 4.1. 2 (This is a real mobile phone) and Android 4.2.2
You can test it by download the app at https://www.dropbox.com/s/9f0yxp5pqqxtcxq/Mirror.zip?dl=0

On Android 5.0 and later, multiple .dex files are automatically loaded by ART together. However, on earlier Android versions, Dalvik starts the application with only the main classes.dex, and the application must load the secondary the .dex files before anything else is done.
This is handled by the multidex support library, but you did not follow the instructions. This means that some of your classes are not present when the system is trying to start your activity, leading to a crash.
Depending on whether you override the Application class, perform one of the following:
If you do not override the Application class, edit your manifest file to set android:name in the <application> tag as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<application
android:name="android.support.multidex.MultiDexApplication" >
...
</application>
</manifest>
If you do override the Application class, change it to extend MultiDexApplication (if possible) as follows:
public class MyApplication extends MultiDexApplication { ... }
Or if you do override the Application class but it's not possible to change the base class, then you can instead override the attachBaseContext() method and call MultiDex.install(this) to enable multidex:
public class MyApplication extends SomeOtherApplication {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
You are currently not overriding Application, so you should follow the first case.
