我正在开发的应用程序在生产中崩溃，用户正在报告以下堆栈跟踪。问题是我自己无法重现它。

Caused by: toothpick.registries.NoFactoryFoundException:

  at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:3206)

对于不同的用户，它在不同的时间在不同的活动中崩溃。如下所示，缺失的工厂存在（至少对我而言）。

public final class MainActivity$$MemberInjector implements MemberInjector<MainActivity> {
  @Override
  public void inject(MainActivity target, Scope scope) {
    target.myLogger = scope.getInstance(MyLogger.class);
    ...
  }
}

失踪的工厂：

public final class MyLoggerImpl$$Factory implements Factory<MyLoggerImpl> {
  @Override
  public MyLoggerImpl createInstance(Scope scope) {
    scope = getTargetScope(scope);
    RestApi param1 = scope.getInstance(RestApi.class);
    Scope param2 = scope.getInstance(Scope.class);
    MyLoggerImpl myLoggerImpl = new MyLoggerImpl(param1, param2);
    return myLoggerImpl;
  }

  @Override
  public Scope getTargetScope(Scope scope) {
    return scope;
  }

  @Override
  public boolean hasScopeAnnotation() {
    return false;
  }

  @Override
  public boolean hasProvidesSingletonInScopeAnnotation() {
    return false;
  }
}

模块：

bind(MyLogger.class).to(MyLoggerImpl.class).singletonInScope();

当使用Toothpick反射或无反射配置时会发生这种情况。关于为什么我得到这个例外的任何想法？

我想出了这个。我以错误的方式使用牙签，当应用程序在后台运行一段时间并且用户重新进入应用程序时，我的范围没有重新创建。

自我注意：当应用程序在后台时，Android 应用程序和活动可以被 Android 杀死。确保应用程序和牙签可以从中安全恢复。保持依赖注入模型简单。
