FAILURE: Build failed with an exception.
What went wrong: Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[16.0. 0]", but isn't
being resolved to that version. Behavior exhibited by the library will
be unknown.
Dependency failing:
com.google.firebase:firebase-measurement-connector-impl:16.0.1 ->
com.google.android.gms:play-servic es-measurement-base#[16.0.0], but
play-services-measurement-base version was 17.2.0.
The following dependencies are project dependencies that are direct or
have transitive dependencies that lead to the art ifact with the
issue. -- Project 'app' depends onto
com.google.firebase:firebase-core#16.0.1 -- Project 'app' depends
onto com.google.firebase:firebase-analytics#17.2.0
For extended debugging info execute Gradle from the command line
with ./gradlew --info :app:assembleDebug to see the dep endency
paths to the artifact. This error message came from the
google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding
"googleServices { disableVersionCheck = false }" to your build.gradle
file.

Gradle throwing exception in a Hello World project

I am trying to add Firebase and google services to my flutter app however Gradle is throwing an exception without any real explanation.
I tried reinstalling both android studio and flutter however the error still happens. I also downloaded the google-services.json file and placed it within the app folder.
My project level gradle looks like this:
buildscript {

Finished with error: Please review your Gradle project setup in the android/ folder.

It's due to AndroidX compatibility,
Create a new project and follow the steps below:
In order for your project to be AndroidX compatible, you need to add the following two lines to your gradle.properties file:
android.useAndroidX = true
android.enableJetifier = true
Make sure in your app build.gradle file that the compileSdkVersion and targetSdkVersion are both set to 28
Remove all the lines with the comment "Remove" from your main app build.gradle file:
android {
compileSdkVersion 28
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
applicationId "YOUR_APPLICATION_ID"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" //Remove
}
buildTypes {
release {
signingConfig signingConfigs.debug
}
}
}
dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2' // Remove
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' // Remove
}
If you try to build the project you will get an error that has something to do with the core library for AndroidX, To fix it, add the code in the subprojects category in your project level build.gradle file:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'androidx.core'
&& !details.requested.name.contains('androidx') ) {
details.useVersion "1.0.1"
}
}
}
}
}
NOTE 1: In the 4th step rememeber that the subprojects category should be bellow the dependecies category, if not present then copy and paste the code given.
I would prefer to try the above steps in Android Studio, Save all the files and restart the project, Add the Firebase dependencies and whatever the changes are told to do in the documentation: Documentation. It would work.
BEST OF LUCK!!

flutter: migrating to androidx

When using android studio, creating a new project and adding the following entries to:
android/build.gradle (dependencies):
classpath 'com.google.gms:google-services:4.3.0'
and android/app/build.gradle (at the bottom)
apply plugin: 'com.google.gms.google-services'
the gradle build fails with the following error:
Finished with error: Gradle task assembleDebug failed with exit code 1
This error goes away when I stop to apply the google-services plugin, which I need for google services.
Flutter is upgraded to the latest version.

To complete the setup of the google play services plugin you have to
add the google-services.json file.
This file is generally placed in the app/ directory (at the root of the Android Studio app module). As of version 2.2.0 the plugin supports build type and product flavor specific JSON files. All of the following directory structures are valid:
// dogfood and release are build types.
app/
google-services.json
src/dogfood/google-services.json
src/release/google-services.json

Could not find method android() for arguments... flutter.gradle issue

I tried to implement Google's recommended changes for "Add Firebase to your app" which states:
The Google services plugin for Gradle loads the google-services.json file you just downloaded. Modify your build.gradle files to use the plugin.
Project-level build.gradle (<project>/build.gradle):
buildscript {
dependencies {
// Add this line
classpath 'com.google.gms:google-services:4.0.1'
}
}
App-level build.gradle (<project>/<app-module>/build.gradle):
dependencies {
// Add this line
implementation 'com.google.firebase:firebase-core:16.0.1'
}
...
// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'
But after making these changes (albeit updated for current versions, ie: services is now 4.2.0 and core is now 16.0.9) I get the following error when trying to run the application:
* Error running Gradle:
ProcessException: Process "X:\Projects\Apps\Flutter\ultimate_mtg\android\gradlew.bat" exited abnormally:

It appears at this stage to be inside the flutter SDK. Here is my flutter.gradle file (extract):

Anyone have any ideas with this one? I have read many similar threads on this and none of the suggestions there are working for me.

Try moving 'com.android.application' to the top of the order in the plugin configs. This seems needed to go first similarly to what have been mentioned on this answer.
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
Though nowadays, you can user flutterfire_cli to configure your app to use Firebase.

Newly created Flutter / Android project fails to build

I am trying to build a newly created Android project (created using flutter create), but the gradle build because of missing dependencies.
I have tried to install a newer version of gradle (using brew install gradle) and tried to change it to that (5.4.1) version without luck. I also read in multiple places that the problem might be a conflict of different httpclient versions being in the class path, but is not the case. I have also tried adding the httpclient dependency directly to the root build.gradle file, but the error remains.

How do install this missing dependency? Shouldn't it be fetched from jcenter for instance?

change the buildscript to:
buildscript {
repositories {
maven {url "https://maven.google.com"}
// google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:3.4.0"
}
}
