Android Credential Manager项目构建失败求助：编译版本不兼容

我开发一个简易Android项目学习Google Credential Manager，在UpsideDownCake或Vanilla模拟器中无法启动应用，构建阶段出现5个AAR元数据校验问题：

• 依赖androidx.credentials:credentials-play-services-auth:1.5.0-alpha04等5个库要求项目编译SDK版本至少为35，但当前项目compileSdk为34；
• 所用Android Gradle Plugin（AGP）8.5.2最高推荐compileSdk版本为34；

已尝试更新依赖版本、切换模拟器系统版本，问题仍未解决。以下是项目配置文件：

解决方法 #

有两种可行方案，按需选择：

方案1：降级Credential Manager依赖版本

选择兼容compileSdk 34的Credentials稳定版，比如1.2.2，修改libs.version.toml中的credentials版本：

credentials = "1.2.2"

该版本无需compileSdk 35，与AGP 8.5.2的推荐compileSdk 34完全兼容，能正常使用Credential Manager核心功能。

方案2：升级AGP版本以支持compileSdk 35

AGP 8.6及以上版本开始支持compileSdk 35，操作步骤如下：

1. 修改libs.version.toml中的AGP版本：

agp = "8.6.0"

2. 在App级build.gradle中更新compileSdk和targetSdk：

android {
    compileSdk = 35
    defaultConfig {
        targetSdk = 35
        // 保留其他原有配置
    }
}

3. 同步项目后，AGP 8.6.0会适配compileSdk 35，满足Credentials库的版本要求。

注：当前Kotlin版本2.0.10与AGP 8.6.0兼容，无需额外修改Kotlin版本。
