I have an app that was building fine before I formated my PC. I installed everything flutter needs and what I had in my previous install and tried to build my app after cloning from github. It results in failure.

This problem seems bizzare. I have tried flutter clean, gradle clean, deleting the .gradle dir from my user dir. Still nothing.
My app used to run perfectly fine a few days ago, I did NOT do any updates and today it is not building.

Solution to the error is;
1 - Open your android/build.gradle & add the following code under your last subprojects
subprojects {
afterEvaluate {project ->
if (project.hasProperty("android")) {
android {
compileSdkVersion 28 --> This is the version in my android/app/build.gradle
buildToolsVersion "28.0.3"
}
}
}
}
2 - Right click to the android[flutter_app_name] folder & go to Flutter -> Open Android module in Android Studio
3 - Under your Project folder open android -> android [appcenter] -> build.gradle & make sure the following Versions are same with the one's in your android/app/build.gradle
compileSdkVersion
buildToolsVersion
minSdkVersion
targetSdkVersion
group 'com.aloisdeniel.flutter.appcenter'
version '1.0-SNAPSHOT'
buildscript {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
}
}
rootProject.allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
apply plugin: 'com.android.library'
android {
compileSdkVersion 28 --> Make sure this version is same with the one in your android/app/build.gradle
buildToolsVersion '28.0.3' --> Make sure this version is same with the one in your android/app/build.gradle
defaultConfig {
minSdkVersion 21 --> Make sure this version is same with the one in your android/app/build.gradle
targetSdkVersion 28 --> Make sure this version is same with the one in your android/app/build.gradle
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
lintOptions {
disable 'InvalidPackage'
}
dependencies {
def appCenterSdkVersion = '1.10.0'
implementation "com.microsoft.appcenter:appcenter:${appCenterSdkVersion}"
}
}
4 - Do the same process for the android [appcenter_analytics] & android [appcenter_crashes].
5 - In terminal type flutter clean and after it finishes type flutter build apk.
Got this err when compiling android, the used to be compiling ok but I have no idea what went wrong.
Ios compiles and works fine tho. I tried a few things including check gradle file has google() and the correct version etc but nothing helps.

I am banging my head on a seemingly simple task.
I want to add firebase authentication to my app. It worked on iOS but as I tried to implement it for android, I systematically get the error :

I am obviously new to Android development, and would prefer not to have to become expert to get the tutorial working. Every solution I found required tinkering with the .gradle files and only apply to react-native.
Thank you for your help !
I also had the same issue and I read that you had to include multiDexEnabled true in the app\build.gradle defaultConfig section. This worked for me.
This error means that some of your dependencies use a different version of the google play services.
You'd have to downgrade/upgrade plugins to unify the version used
Change minSdkVersion in android/app/build.gradle from 16 to 21
Final Versions
pubspec.yaml
cloud_firestore: ^0.8.2+3
android/build.gradle
classpath 'com.google.gms:google-services:3.2.1' // Google Services plugin
android/app/build.gradle
targetSdkVersion 27
minSdkVersion 21
Solved : incompatible versions used between plugin and framework.
Google SignIn plugin 0.4.0 and above should be used with new projects created with flutter create in its latest version.
The codelab is no longer valid and should be updated.
This link solved the same issue for me.
First I set dependencies in my pubspec.yaml to
dependencies:
flutter:
sdk: flutter
cloud_firestore: ^0.8.2
and ran flutter packages get in my IDE's terminal.
Also I had to change the minimum target SDK version:
Open android/app/build.gradle, then find the line that says
minSdkVersion 16.
Change that line to minSdkVersion 21.
Save the file.
This alone may fix your problem; however I had to also do the following because some of my dependency versions were mismatched.
I had to open android/app/build.gradle, then add the following line as the last line in the file:
apply plugin: 'com.google.gms.google-services'
Next, I had to open android/build.gradle, then inside the buildscript tag, add a new dependency:
buildscript {
repositories {
// ...
}
dependencies {
// ...
classpath 'com.google.gms:google-services:3.2.1' // new
}
}
After this my app finally ran on the android emulator.
The link has a more complete walkthrough if you get stuck.
Also, to note, I did not have to set multiDexEnabled to true.
The problem here may be that the plugins you are depending on have conflicting gradle dependencies.
This SO answer here https://stackoverflow.com/a/49901209/90918 provides a description of how to solve this problem by finding the conflicting dependencies and overriding them.
Quoting the original answer:
Your two packages seem to disagree on their transitive dependencies.
One wants 11.6.+, the other wants 11.+ of some play-services
dependencies. Since both 11.6.2 and 11.8.0 are out there, this is
going to end up with a conflict.
If you run ./gradlew androidDependencies in your android/ folder,
you get a listing of the result of dependency resolution, containing,
among others, the following:
+--- :flutter_google_place_picker (variant: release)
+--- com.google.android.gms:play-services-location:11.8.0#aar
+--- com.google.android.gms:play-services-places:11.6.2#aar
+--- com.google.android.gms:play-services-maps:11.6.2#aar
+--- com.google.android.gms:play-services-base:11.8.0#aar
+--- com.google.android.gms:play-services-tasks:11.8.0#aar
+--- com.google.android.gms:play-services-basement:11.8.0#aar
These 11.6.2 and 11.8.0 packages are not going to work together. To
resolve this, you need to patch your dependencies to be consistent
with each other, or add a dependency override to the top level of your
android/app/build.gradle file and hope for the best:
configurations.all {
resolutionStrategy {
force 'com.google.android.gms:play-services-places:11.8.0'
force 'com.google.android.gms:play-services-location:11.8.0'
}
}
I had the same problem
I ve added on my App/build.gradle on android/defaultConfig the line :
multiDexEnabled true
and on dependencies
implementation 'androidx.multidex:multidex:2.0.1'
App/build.gradle look like this:
def localProperties = new Properties()
...
android {
compileSdkVersion 28
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
....
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
flutter {
source '../..'
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
.....
implementation 'androidx.multidex:multidex:2.0.1'
}
it works for me
The reason is you are using the different version of dependencies. To fix this go to your project/App/src/ and open Build.gradle. Then Add multiDexEnabled true Line inside the default config section.
Ex:Like this
defaultConfig {
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
I had added admob_flutter: ^0.3.4 in my flutter app but didn't used anywhere. Removing from pubspec.yaml file works for me.
