NoClassDefFoundError Landroid/arch/lifecycle/LifecycleDispat

Question

我想尝试谷歌(https://developer.android.com/arch(的新生命周期内容，但在打开应用程序时崩溃。我所做的只是添加依赖项。还有其他人有这个问题吗？

Answer 1

你使用Proguard吗？如果是这样，请尝试将其关闭：

debug {
    minifyEnabled false
    useProguard false
}

或者，您可以将自定义规则添加到Proguard配置中：

-keep class android.arch.** { *; }

Answer 2

在我的场景中，在应用程序的build.gradle中添加依赖项使用的是需要这些依赖项的库

对于安卓 X

    implementation "androidx.lifecycle:lifecycle-extensions:2.0.0"
    

确保 android X 已启用 gradle.properties 和 Jetfier

     android.useAndroidX=true
     android.enableJetifier=true

对于支持版本

   implementation "android.arch.lifecycle:extensions:1.1.1"

Answer 3

即使

没有Proguard，也会发生这种情况。 今天，我可以通过在Android Studio中创建示例Flutter应用程序，然后运行"Flutter pub upgrade"来创建问题。

对我有用的解决方案是添加到"依赖项"下的app build.gradle文件中

依赖关系 { ... 实现 'com.android.support：appcompat-v7：28.0.0' }

如果您的应用使用 androidx，请添加到 gradle.properties 文件中：

android.useAndroidX=true android.enableJetifier=true

Answer 4

我正在使用一些 gradle 配置

android.enableR8.desugaring=false
android.enableJetifier=true
android.useAndroidX=true

为了再次工作，我删除了 gradle.properties 文件的android.enableR8.desugaring=false
