Android Build Failed

[Hadjimamas]

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':webview_cookie_manager'.

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: C:\Users\Name\AppData\Local\Pub\Cache\hosted\pub.dev\webview_cookie_manager-2.0.6\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.

I'm having this issue when attempting to build an APK:

Execution failed for task ':webview_cookie_manager:verifyReleaseResources'. A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action Android resource linking failed ERROR:/home/user123/code/ce/flutter/build/webview_cookie_manager/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found.

Is there a solution?

This is already resolved by me in August 2023. My fix in on master via #66 in March 2024. However there is no release with this fix!

In the past I suggested to use my fork, but after some discussions with some other devs, that was a bad idea (since I linked the main branch which I could update in the future).

To use my patch with the official (this) repository you need to change the dependency to this:

  webview_cookie_manager:
    git:
      url: https://github.com/fryette/webview_cookie_manager.git
      ref: 4bb434b4a47fe806e95ffc1be28fe4366e5bbd64

The reference is the merge commit of my fix. See #66 to verify it.

I was also facing similar issues what worked for me is manually updating following files:

1. IN AndroidManifest:

...\Pub\Cache\hosted\pub.dev\webview_cookie_manager-2.0.6\android\src\main\AndroidManifest.xml

FROM:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="io.flutter.plugins.webview_cookie_manager">
</manifest>

TO:

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
</manifest>

2. IN BUILD.GRADLE:

"...\Pub\Cache\hosted\pub.dev\webview_cookie_manager-2.0.6\android\build.gradle"

FROM

group 'io.flutter.plugins.webview_cookie_manager'
version '1.0'

buildscript {
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
    }
}

rootProject.allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url "https://storage.googleapis.com/download.flutter.io" }
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28

    defaultConfig {
        minSdkVersion 16
    }
    lintOptions {
        disable 'InvalidPackage'
    }
}

dependencies {
    testImplementation 'junit:junit:4.13.1'
}

TO:

group 'io.flutter.plugins.webview_cookie_manager'

buildscript {
    repositories {
        google()
        mavenCentral()
    }
