Question

java.lang.RuntimeException: Unable to start activity 
ComponentInfo{com.package.application/com.package.application.MainActivity}: 

java.lang.ClassCastException: com.package.application.DaggerAppApplication_HiltComponents_ApplicationC$ActivityRetainedCImpl$ActivityCImpl 
cannot be cast to com.package.application.MainActivity_GeneratedInjector

Answer 1

Solved it by adding missing dependency for androidx hilt.

kapt  androidx.hilt:hilt-compiler:1.0.0-alpha01

在我的梯度档案中,我有其他受扶养人。

implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha02"
implementation  com.google.dagger:hilt-android:2.28-alpha 
kapt  com.google.dagger:hilt-android-compiler:2.28-alpha 
implementation "androidx.fragment:fragment-ktx:1.2.5"

Plus fragment and its activity who are injecting viewmodel using hilt both are annotated as @AndroidEntryPoint

Answer 2

What worked for me:

Removed the @AndroidEntryPoint annotation from the activity.
Ran the code and of course, it failed.
Had a fragment inside the activity. So, I deleted the fragment code as well.
Ran the code, it failed.
Added the @AndroidEntryPoint annotation to the activity again.
Ran the code. It ran and the error disappeared.

Answer 3

作为对我来说,作为我在<处>的扶养声明,build.gradle,即必须使用<>api而不是><>>:

api Project (:features:feed Module >

Update: Dagger team released classpath aggregation feature which can resolve this issue. You can learn more here: https://dagger.dev/hilt/gradle-setup#classpath-aggregation

基本上,在你的评价模块build.gradle上,你需要补充:

hilt {
    enableExperimentalClasspathAggregation = true
}

如果在项目中使用的 Android平金字本少于7.0,确保也能够增加。格勒布档案:

android {
    ...
    lintOptions {
        checkReleaseBuilds false
    }

Answer 4

在我的案件中,我收到了类似的<编码>。由于我<代码>的模块 HiltAndroid App 对应班子可以进入我的@AndroidEntryPoint活动所在的模块。将我的应用类别移至配套模块(能够进入所有其他格拉门模块)解决了这一问题。

https://developer.android.com/training/dependency-injection/hilt-android#hilt-modules” rel=“noreferer”

由于Hilt公司的代码生成需要进入使用Hilt的所有格拉斯模块,因此汇编你的应用等级的格拉斯模块也需要有你的所有功能。在其过境附属地的Hilt模块和构造班。

Answer 5

我花了几个小时的时间来确定这一准确问题,但通过对所有单元进行无效的切身/重塑和重新建设来解决。

This is related to this issue from Hilt: Hilt: More meaningful error messages

Answer 6

即使该法典正确,但有时大错不行。

一种可能的解决办法是,将这一类重新命名为“Class2”类,重新开具,并检查它是否奏效。如果工作,则将班级重新命名为原班。

Answer 7

这是通过无效的海滩和重新启动解决的。

Answer 8

我也存在同样的问题,这里我采取了以下步骤:

appModule starts with internal

在您的级别上建设。甲型六氯环己烷

   enableExperimentalClasspathAggregation = true
}

我的依托是:


classpath "com.google.dagger:hilt-android-gradle-plugin:2.40.5"

    app-level build.gradle: 
     top plugin section

 plugin{
  ...........
  id  kotlin-kapt 
  id  dagger.hilt.android.plugin 
 }

     dependencies section
     //dagger-hilt
 implementation  com.google.dagger:hilt-android:2.40.5 
 kapt  com.google.dagger:hilt-android-compiler:2.40.5 ```

Answer 9

这是一种真正的sil性解决办法,但只是对注射通知和投放场发表评论,然后管理 app,并再次运行。

Answer 10

It s also happened to me when I m importing an .aar with "implementation". (an .aar which includes hilt)

同一样,你不使用“api”增加汇编时间,而是可以在你的建筑中添加以下内容。梯度(申请)

hilt {
    enableAggregatingTask = true
}

enableExperimentalClasspathAggregation 现在已经做了解释,

见。

Answer 11

I was having the same java.lang.ClassCastException after adding Hilt. Steps to fix the problem:

1. Build -> Clean Project
2. Build -> Rebuild Project

另外,卡普切特也没有工作。仅添加一个图形:

id  dagger.hilt.android.plugin

然后,增加Hilt Dependcies:

implementation "com.google.dagger:hilt-android:2.38.1"
annotationProcessor "com.google.dagger:hilt-compiler:2.38.1"

Answer 12

www.un.org/Depts/DGACM/index_spanish.htm 需要采取的步骤:

Remove .gradle file in app s directory
Invalidate cache and restart android studio

希望它将解决你的问题。

Answer 13

对我来说,我原想把@AndroidEntryPoint<>/code>添加到一个叫作第二个活动的母体活动上,另一个叫作碎块。显然,他们每个人都需要@AndroidEntryPoint。

Answer 14

你可以删除你身上的fold,并删除你系统中的梯度。

rm -rf app/build

rm -rf ~/.gradle/caches/build-cache-1

仅仅拆除建筑的海滩比拆除所有的陈列室。

Answer 15

在我的案件档案中,这套材料没有包含,因此无法绘制档案,无法在制作的夹中生成。因此,<代码>hilt无法解决档案。

I added the package in the fragment, and it resolve my issue

Answer 16

在我的案件中,我是两度 setting子,造成了错误:

(a) 在安乐施会档案中:

    <activity
        android:name=".MainActivity"
        android:exported="true"
        android:launchMode="singleTask"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustNothing"
        tools:ignore="LockedOrientationActivity">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

        <nav-graph android:value="@navigation/navigation_app_graph" />
    </activity>

活动一度——主轴:

    <androidx.fragment.app.FragmentContainerView
        android:id="@+id/nav_host_fragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:defaultNavHost="true"
        app:layout_constraintBottom_toTopOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:navGraph="@navigation/navigation_app_graph"
        tools:ignore="UnusedIds"
        tools:layout="@layout/fragment_mosaic" />

活动标的内线的导航图为主要活动确定导航图。这正是你为这一活动配置导航图的地方。

您可以删除其他定义,该定义是内部的;androidx.fragment.app.FragmentContainerView>

app:navGraph="@navigation/navigation_app_graph"

After all, the navigation graph has already been defined for the main activity, and you don t need to define it again inside the FragmentContainerView.
