twilio_voice not compatible with latest android gradle plugin (>= 8.x.x)

Issue Summary

1: Task failed with an exception.
-----------
* What went wrong:
A problem occurred configuring project ':twilio_voice'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
   > Namespace not specified. Specify a namespace in the module's build file: /Users/jd-bus/.pub-cache/hosted/pub.dev/twilio_voice-0.1.3/android/build.gradle. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.
     
     If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.

Steps to Reproduce

Use gradle-8.8-all.zip or any gradle above 8.x.x In android/gradle/wrapper/gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-8.8-all.zip

./gradlew build

After extensive configuration, I have successfully resolved the issue. Here are the steps taken:

1- Open the Android module in Android Studio. 2- Run the flutter clean command at the root level of your Flutter project. 3- Sync the Android project in Android Studio. 4- Modification in your project files: in-app level build.gradle

update compileSdk to 35
set targetSdkVersion to 35
set minSdkVersion to 26
set JavaVersion to 17 example: sourceCompatibility JavaVersion.VERSION_17 targetCompatibility JavaVersion.VERSION_17

You can do these modifications directly in you app level build.gradle file and in flutter.groovy file as well.

5- Go to setting.gradle set following versions for gradle and kotlin

id "dev.flutter.flutter-plugin-loader" version "1.0.0"
id "com.android.application" version '8.5.1' apply false
id("org.jetbrains.kotlin.android") version "1.9.23" apply false

6- Got to gradle-wrapper.properties and update distributionUrl with distributionUrl=https://services.gradle.org/distributions/gradle-8.7-bin.zip

7- In module level build.gradle of twilio_voice

update compileSdk to 35 and add namespace = "com.twilio.twilio_voice"
update JavaVersion to 17 Example: compileOptions { sourceCompatibility JavaVersion.VERSION_17 targetCompatibility JavaVersion.VERSION_17 }

kotlinOptions { jvmTarget = '17' }
update minSdkVersion to 26
Update kotlin version to example kotlin_version = '1.9.23'
update build tools to classpath 'com.android.tools.build:gradle:8.5.1'

8- Sync the project again. 9- Clean the project once more and run the build. Happy debugging! If you have any questions, feel free to ask.

Summary:

Add the namespace in the Gradle file of the library.
Upgrade the Gradle version and SDK level to the latest for both the library and your project.
Ensure the Gradle version, SDK levels, and Kotlin version are the same for both your project and the library.
Use Java 17 instead of Java 11 or 1.8.
