AAPT：错误：找不到样式属性“android:attr/windowSplashScreenBackground”

Question

我使用 Android Studio Canary 时遇到了同样的错误。

它在 Gradle 4.2.1 和 Gradle 最新版本 7.1.0-alpha09 中返回相同的错误。（即错误日志如下）

此外，我还更新了：

1. SDK 平台至 Android 12(S)。
2. Plus SDK Build Tools 更新为 Android SDK Build-Tools 31

我必须在哪里/如何实现这些样式属性？我已将以下项目添加到 Styles.xml

很可能是我的重复很可能是我的问题

我猜你没有改变主题父级。

随着最新的更新，Android 12 附带了SplashScreen API确保从 Android 12 开始正确显示启动画面。

要访问它，您必须升级您的gradle文件并将主题父级更改为Theme.SplashScreen. 在你的 gradle 中添加：

android {
    //before syncing please make sure Android API 12 is installed in SDK manager
    compileSdkVersion 31 
    ...
}
dependencies {
    ...
    implementation 'androidx.core:core-splashscreen:1.0.0-alpha01'
    ...
}

style.xml为启动画面创建一个单独的

android {
    //before syncing please make sure Android API 12 is installed in SDK manager
    compileSdkVersion 31 
    ...
}
dependencies {
    ...
    implementation 'androidx.core:core-splashscreen:1.0.0-alpha01'
    ...
}

在清单中设置主题<application>

<manifest>
   <application 
   ...
   android:theme="@style/Theme.MySplashScreen">
   ...

最后在MainActivity您的启动活动中加载启动屏幕，然后在onCreate()之前设置它setContentView()

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        installSplashScreen()

        setContentView(...)
}
