RuntimeException:ClassNotFoundException android.arch.lifecycle.ProcessLifecycleOwnerInitializer

Question

我只在 Android SDK < 5.0 上收到此错误。所以 4.0、4.2、4.3 等等。任何运行 Android 5.0+ 都可以完美运行。有任何想法吗？启动时崩溃。

按照本指南进行设置 -> https://developer.android.com/topic/libraries/architecture/adding-components.html

App.java

public void onCreate() {
    super.onCreate();

    ProcessLifecycleOwner.get().getLifecycle().addObserver(new AppLifecycleListener(this));
    registerActivityLifecycleCallbacks(this);
}

AppLifecycleListener.java

public class AppLifecycleListener implements LifecycleObserver {
private App app;

public AppLifecycleListener(App app)
{
    this.app = app;
}

@OnLifecycleEvent(Lifecycle.Event.ON_START)
public void onMoveToForeground() {
    if (app.getCurrentActivity() instanceof BaseActivity)
    {
        BaseActivity baseActivity = (BaseActivity) app.getCurrentActivity();
        baseActivity.runIsAPIVersionCheck();
        baseActivity.fetchObjectsWithHUD(false);
    }
}

@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
public void onMoveToBackground() {}

}

Gradle

    javaMaxHeapSize "4g"

Answer 1

这最终成为一个 multdex 问题。我按照此处的文档 -> https://developer.android.com/studio/build/multidex.html#mdex-gradle 进行操作，现在效果很好！

Gradle:

implementation 'com.android.support:multidex:1.0.3'

App.java:

public class App extends Application implements Application.ActivityLifecycleCallbacks {

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

Answer 2

将以下内容添加到您的 ProGuard 文件中。自 Android Architecture Components 1.0.0 (source) 以来，这应该不是必需的，但显然它仍然是。

-keep class * implements android.arch.lifecycle.GeneratedAdapter {<init>(...);}

Answer 3

我所要做的就是将以下内容添加到我的 proguard-rules.pro 文件中：

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

Answer 4

在我的例子中，android 架构生命周期文件以某种方式被 Android 捆绑在 Pie(Android9) 上。所以我所做的是在 proguard-rules.pro

中添加相同的 keep 语句

对于 AndroidX :

-keep class androidx.lifecycle.** {*;}

支持：

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