Android embedding v2

[Theunodb]

Getting this when i'm trying to run my app:

This app is using a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to migrate this app to the V2 embedding.
Take a look at the docs for migrating an app: https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects
The plugin `appsflyer_sdk` requires your app to be migrated to the Android embedding v2. Follow the steps on https://flutter.dev/go/android-project-migration and re-run this command.

Hi @Theunodb, Thank you for reaching out to us.

I believe that your app was created before Flutter v1.12, and your MainActivity is still extending FlutterActivity imported from io.flutter.app.FlutterActivity. This class is now deprecated in Flutter, and you have to migrate your project following this guide. If this message still exists after migrating your project, please check your 3'rd party dependencies and make sure they aren't using the deprecated Android embedding.

hi @Theunodb , thanks for reaching to us.

To remove this problem just follow my steps: Step1: Open Main Activity of Android (JAVA/Kotlin) Replace the main activity with this line of code .......................................................................................................... import io.flutter.embedding.android.FlutterActivity;

class MainActivity: FlutterActivity() { } ............................................................................................................ Step 2: Open AndroidManifest.xml Make these changes ............................................................................. replace this:- android:name="${applicationName}" ............................................................................................................................................................. replace meta data with this one ....................................................................................................................................................................... and after that you might need to upgrade your compileSdkVersion 31,

then flutter clean, flutter pub Get, flutter Pub upgrade RUN THE PROGRAM

@Blacktaler can you mention which version of flutter are you using to create flutter application? I tried creating in version 3.0.2 on stable branch and this error is not present.

That time I was using 2.10.3 - version of flutter and I was having errors like that

Hi I have same error when using open file PDF

he plugin open_file uses a deprecated version of the Android embedding. To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs. If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugi

Only the developers of the plugin can upgrade it to next level or until you how how the plugin is coded

I have followed the following steps but it is still showing the error. This app is using a deprecated version of the Android embedding. To avoid unexpected runtime failures, or future build failures, try to migrate this app to the V2 embedding. Take a look at the docs for migrating an app: https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects The plugin firebase_analytics requires your app to be migrated to the Android embedding v2. Follow the steps on the migration doc above and re-run this command.
