SingletonComponent 缺少父声明

Question

我刚刚将我的 android Hilt-Dagger 依赖项更新为 1.0.0-alpha03
我认为 ApplicationComponent 是 deprecated
并替换为 SingletonComponent
但是一旦我用我的代码替换它，它就会显示这个错误除了更换它，我还需要做任何其他事情吗？

完全错误

Answer 1

尝试将您的刀柄-android-编译器更新为

kapt "com.google.dagger:hilt-android-compiler:2.37"

您可以导入 SingleComponent class，但 kapt 无法正确处理它。

刀柄版本和 kapt 版本匹配很重要。这是我当前的设置。

// HILT
def hilt_version = "2.37"
implementation "com.google.dagger:hilt-android:$hilt_version"
kapt "com.google.dagger:hilt-android-compiler:$hilt_version"

Answer 2

当 Android 工作室建议将刀柄从 2.28 升级到 2.31 时，我就遇到了这种情况。但它没有建议使用 kapt。确保两者都是 2.31.

Answer 3

就我而言，为@mikeBlack 和@user2343647 的答案增加价值。确保所有三个都更新为相同的版本号。模块级别 build.gradle

implementation "com.google.dagger:hilt-android:2.36"

kapt "com.google.dagger:hilt-android-compiler:2.36"

和项目级别 build.gradle

classpath "com.google.dagger:hilt-android-gradle-plugin:2.36"

将 2.36 替换为最新版本。
