Build Failure: :unique_identifier:verifyReleaseResources Task Failed

Issue Title

Build Failure: :unique_identifier:verifyReleaseResources Task Failed

Description

The build process failed for the :unique_identifier module during the release build with the following exception:

Execution failed for task ':unique_identifier:verifyReleaseResources'.
> A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action
   > Android resource linking failed
     ERROR: D:\Programming\flutter_projects\Freelance\Rasid Apps\rasid-dashboard\build\unique_identifier\intermediates\merged_res\release\values\values.xml:194: AAPT: error: resource android:attr/lStar not found.

Steps to Reproduce

1. Attempt to build the release version of the application.
2. Observe the failure during the verifyReleaseResources task of the :unique_identifier module.

Expected Behavior

The release build should succeed without any resource linking errors.

Actual Behavior

The build fails due to a missing android:attr/lStar resource during the verifyReleaseResources task.

Possible Solutions

• Verify the Android Gradle Plugin version. Update to a version that supports the android:attr/lStar attribute.
• Update the compile SDK version in the build.gradle file to a level that includes this attribute (e.g., SDK 31 or above).

Logs and Output

Relevant Log Snippet:

> Android resource linking failed
     ERROR: D:\Programming\flutter_projects\Freelance\Rasid Apps\rasid-dashboard\build\unique_identifier\intermediates\merged_res\release\values\values.xml:194: AAPT: error: resource android:attr/lStar not found.

Additional Context

This issue often arises when there is a mismatch between the Android Gradle Plugin version and the compile SDK version. Ensure the dependencies and plugins are compatible with the project's target SDK version.

@MazenxELGayar can you please post both your gradle files.

[MazenxELGayar]

Sure, here are the two Gradle files you requested:

First build.gradle (Module: app):

plugins {
    id "com.android.application"
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
}

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    namespace "com.example.<app_name>" // Redacted application ID
    compileSdkVersion 34
    ndkVersion flutter.ndkVersion

    compileOptions {
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        applicationId "com.example.<app_name>" // Redacted application ID
        minSdkVersion 23
        targetSdkVersion 33
        versionCode 18
        versionName flutterVersionName
        multiDexEnabled true
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias'] // Keystore alias kept generic
            keyPassword keystoreProperties['keyPassword'] // Keystore password kept generic
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword'] // Keystore store password kept generic
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation 'androidx.window:window:1.0.0'
    implementation 'androidx.window:window-java:1.0.0'
    coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.2.2'
}

Second build.gradle (Project-level):

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

Let me know if you need further adjustments!

I created a new flutter app and used your gradle files. I am able to run the app and create the app bundle by using flutter build appbundle.
I think this issue could be coming because of gralde version.
the new app has this: gradle > wrapper > gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-all.zip

can you provide this value?
and can you try to update this if you are using an older value

check this: resource android:attr/lStar not found:
After updating flutter to 3.24, this problem arose again. It is related to the fact that now flutter checks the versions of compileSdkVersion and buildToolsVersion. Some packages either specify outdated versions or do not specify them at all.

android/settings.gradle:
changed distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip to ``distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-all.zip

android/gradle/wrapper/gradle-wrapper.properties:
and id "org.jetbrains.kotlin.android" version "1.8.22" apply false to id "org.jetbrains.kotlin.android" version "2.0.0" apply false
but still facing the same problem:

@MazenxELGayar can you try and use my branch 0.4.1 ?
I have tried a few things... let me know if this works.
ou can use this like this

unique_identifier: git: url: https://github.com/karantanwar/unique_identifier.git ref: 0.4.1
