Unity Android plugin: error: resource android:attr/IStar not found

Question

我正在使用 Kotlin 为 Unity 开发 Android 蓝牙插件。我包含了我的 Kotlin 库的 .aar 文件（它在 Android Studio 中的应用程序运行中完美运行），并且由于我在运行时遇到一些依赖性错误，我开始使用 Android Dependency Resolver plugin.

我首先添加了我的库对其 .gradle 文件的依赖项：

dependencies {
    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.4.0'
    implementation 'com.google.android.material:material:1.4.0'

    // For Kotlin Coroutines
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.5.2'
    
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

我的图书馆 *Dependencies.xml，按照依赖关系解析器 here 的指示：

<dependencies>
  <androidPackages>
    <repositories>
      <repository>https://repo.maven.apache.org/maven2</repository>
    </repositories>

    <androidPackage spec="androidx.appcompat:appcompat:1.4.0">
      <androidSdkPackageIds>
        <androidSdkPackageId>extra-google-m2repository</androidSdkPackageId>
      </androidSdkPackageIds>
      <repositories>
        <repository>https://maven.google.com</repository>
      </repositories>
    </androidPackage>

    <androidPackage spec="androidx.core:core-ktx:1.7.0">
      <androidSdkPackageIds>
        <androidSdkPackageId>extra-google-m2repository</androidSdkPackageId>
      </androidSdkPackageIds>
      <repositories>
        <repository>https://maven.google.com</repository>
      </repositories>
    </androidPackage>

    <androidPackage spec="org.jetbrains.kotlinx:kotlinx-coroutines-android:1.5.2">
      <androidSdkPackageIds>
        <androidSdkPackageId>extra-google-m2repository</androidSdkPackageId>
      </androidSdkPackageIds>
      <repositories>
        <repository>https://maven.google.com</repository>
      </repositories>
    </androidPackage>

  </androidPackages>
</dependencies>

Dependency Resolver 可以正常工作，但当我尝试编译项目时出现错误：

FAILURE: Build failed with an exception.

Answer 1

lStar首先定义在android-31，所以可以把compileSdkVersion改成31+，或者把androidx改成低版本。

Answer 2

Dependency Resolver 存在错误，您可以追踪我同时发现的相关问题here, as well as a workaround。记得在 Assets -> External Dependency Manager -> Android Resolver -> Settings.

下关闭 Enable Resolution On Build
