我将
DaggergiSubapplicationComponent
类的错误输入到应用程序类中，如下所示：

component = DaggerGithubApplicationComponent.builder()
        .contextModule(new ContextModule(this))
        .networkServiceModule(new NetworkServiceModule("https://api.github.com/"))
        .build();
总结以下方面的讨论：

2个问题：

  • @tux world出现了一条警告消息：
    • 警告：使用不兼容插件进行注释处理：android-apt。这可能会导致意外行为。 2.
    组件
    类的名称应不正确

    解决方案：

  • 修复项目中的
    apt
    ，将生成缺少的代码：
    • a） Gradle插件
    2.2.3
    ，
    android apt:1.7
    ，
    apt
    在您的模块构建中。Gradle

    b） Gradle插件
    2.3.1
    ，在您的模块
    build.Gradle

  • 修复生成的
    组件
    类的错误名称
    • 只需清理、构建并导入ir.pishguy.testdagger.Dagger.Components.DaggerGithubApplicationComponent；。您需要dagger为您生成代码。只是运行应用程序来检查是否有任何错误。作品fine@Raghunandan我没有在项目中得到任何其他错误，
    import ir.pishguy.testdagger.Dagger.Components.DaggerGithubApplicat‌​离子组分不解决我的问题和
    Daggergithubapplicate‌​ionComponent
    在我的项目中是未知的，您能看到git存储库吗？提前谢谢，我克隆了你的回购协议，只是做了清理和构建，我看不出有任何问题。事实上，我在手机上运行了这个应用程序。它的fine@tux-你有没有试过拉古南丹说的话？让我换一种说法：1。临时注释所有
    DaggerGithubApplicationComment
    内容。2.暂时删除
    DaggerGithubApplicationComment
    import。3.构建一个干净的项目。4.反向执行步骤1。和2.@Bartklipinski我想知道会发生什么！！！我清理、重建项目，然后构建项目，现在我希望创建
    daggergithubapplicate‌​‌​ionComponent
    并且可以导入，我没有任何关于该组件的
    导入
