The error i\'m rece

Answer 1

You are getting this error because you a have library module which has the same package name as the app module.

The solution would be to change package name of your library module. You can follow the accepted answer in this SO which describes how to change the package name in android studio.

Answer 2

I had this problem after an android x upgrade in android studio. To fix this I went to File->Open and opened the android folder within my current flutter project. I was then able to go to Build->Clean Project as suggested by @Seymour Mammadli.

Hopefully this helps someone with the same issue.

Answer 3

go to android folder and fire the below command

./gradlew clean

Answer 4

Just goto tools>Flutter>Flutter clean in android studio. It'll resolve the issue. (If you are working with flutter)

Answer 5

I solved this error enabling multiDexEnabled in the build.gradle of my app's module:

defaultConfig { 
    ...
    ...
    ...

    multiDexEnabled true
}

Answer 6

I encountered the issue building a Flutter application and I resolved it following the official guide: https://developer.android.com/studio/build/multidex

You simply have to:

0. (Android: Go to Refactor > Migrate to AndroidX
(If you are on a Flutter project, to migrate the module, you have to go to Tools > Flutter > Open for Editing in Android Studio

1. (Both) Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 28
        multiDexEnabled true
    }
    ...
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

2. (non-Flutter) 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>

2. (Flutter) 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=".App" >
        ...
    </application>
</manifest>

3.(Flutter) Create a custom class under project/android/app/src/main/[java or kotlin folder]/[your/package/appName]
kotlin version: App.kt

package your.package.appName

import io.flutter.app.FlutterApplication
import android.content.Context
import androidx.multidex.MultiDex

class App : FlutterApplication() {

    override fun attachBaseContext(base: Context) {
        super.attachBaseContext(base)
        MultiDex.install(this)
    }

}

java version: App.java

package your.package.appName;

import io.flutter.app.FlutterApplication;
import android.content.Context;
import androidx.multidex.MultiDex;

public class App extends FlutterApplication {

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }

}

4. (Both) Celebrate if you did it!! :D
