SingletonComponent缺少父声明

Question

我刚刚将我的android Hilt依赖项更新为1.0.0-字母03。

我认为ApplicationComponent是废弃的

代之以SingletonComponent

但是，一旦我在代码中替换了它，它就会显示出这个错误，除了替换它之外，我还需要做什么吗？

全误差

提前谢谢。

Answer 1

尝试将hilt android编译器更新为

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

您可以导入SingleComponent类，但是kapt未能正确地处理它。

重要的是，两者的刀柄版本和kapt版本相匹配。这是我目前的设置。

// 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hilt从2.28升级到2.31时，我就遇到了这种情况。但这并不意味着凯普特。确保两者都是2.31。

Answer 3

在我的例子中，将值添加到@mikeBlack和@ answer 2343647答案。确保这三个版本都更新为相同的版本号。模块级build.gradle

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

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

和项目级build.gradle

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

用最新版本取代2.36。
