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.运行Android 5.0+的任何东西都能完美运行.有任何想法吗？发射时崩溃.

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() {}

}

Answer 1

这最终成为一个多指数问题.我按照这里的文档 - > https://developer.android.com/studio/build/multidex.html#mdex-gradle,现在效果很好!

摇篮:

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

我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.** {*;}
