How to fix flutter AndroidX incompatibility?

Question

I just import webview_flutter plugin and found that the plugin has incompatible with my flutter environment. Then using Android Studio I migrate my AndroidX environment with "Migrate to AndroidX" option.

I want to use webview_flutter plugin for viewing the page. Help appreciated.

Here is the error message

Answer 2

I have tried the best ever possible ways to break it down. I have been trying to use youtube videos from URL using the youtube video flutter plugin and getting androidx incompatibilities plugin error. Finally, I found the result. Just update

1. the build.Gradle file in android - classpath 'com.android.tools.build:gradle:4.1.0'
2. gradle-wrapper.properties

distributionUrl=https://services.Gradle.org/distributions/gradle-6.7-all.zip update the value as above it will work perfect, as for me.

Answer 3

Just Enable multidex in app/build.gradle file.

defaultConfig {   
     ....
     multiDexEnabled true             
 }

dependencies {
    .....
    implementation 'com.android.support:multidex:2.0.1'
}

Answer 4

I found this solution on Github by @tiklupxgit, solved this issue quickly.

Update this line in [Project Directory]/android/build.gradle

classpath 'com.android.tools.build:gradle:3.5.4'

Now run these commands in your terminal under [Project Directory]

flutter clean && flutter pub get

Finally, build your project again.

Answer 5

Ok I finally solved the problem thanks to @Navpreet Singh

In order to fix the problem of the default grey icon of Firebase FCM (on Xiaomi devices) I added in the Manifest:

From then on, I got this error when building the application:

Running Gradle task 'assembleDebug'...
Running Gradle task 'assembleDebug'... Completed 20,2s The build failed probably because of AndroidX incompatibilities in a plugin. The tool is about to try to use Jetifier to resolve the incompatibility. Building the cloud_firestore plugin... Exception: The cloud_firestore plugin could not be built because of the above problem. Running the Gradle task 'assembleAarRelease'...

When I commented out the metadata in the Manifest, the program started to compile again.

Answer 6

For me, I copied settings.gradle file to the new file settings_aar.gradle

Then Removed the following code from settings_aar.gradle:

 def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()
 def plugins = new Properties()

You need to open your project in the android studio.
select Refactor->Migrate to Androidx(You need to migrate Android Project not 
flutter one)
Android Studio finish some process you have to wait for it .
Than rebuild your project and it will work fine.

Create a new flutter project and move existing code to it: flutter migration

flutter create --androidx -t <project-type> <new-project-path>

eg: flutter create --androidx -t app .

Answer 9

Thanks for your suggestion,

I've fixed it by doing these steps : 1. Try adding this line In your Project folder > android > app > build.gradle, add the following Line in

multiDexEnabled true

inside defaultConfig

2. Then upgrade gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (previously on version 3.2.1)

3. Run flutter clean and rebuild your project

Answer 11

First make sure that all your packages in the pubspec.yaml are of the latest version. Then open the android project of your flutter app with android studio, select Refactor->Migrate to Androidx(make sure that you are doing that that from the android project and not from the flutter one). Wait until android studio finishes migrating your project, rebuild your project. Hope it helps!
