NoClassDefFoundError: android.app.PictureInPictureParams
NoClassDefFoundError: android.app.PictureInPictureParams
提问于 2017-12-11 14:15:48
我使用的是EasyPermission库，当我想接受存储权限时，我的应用程序会崩溃，StackTrace如下：

}我已经尝试过几件事了：
- 清洁/重建
- 禁用即时运行
- 在GitHub的EasyPermission页面上被问到，但是导致了一个“不是由于库的错误”(这是正确的)
- 在"multiDexKeepFile“上添加文件
- 在"multiDexKeepProguard“上添加文件
关于第4点和第5点，我是如何创建文件的(也许我做错了)：
MultiDexKeepFile
android/app/PictureInPictureParams.classMultiDexKeepProguard
-keep class android.app.PictureInPictureParams我在我的项目的根目录和'app‘目录下添加了它们(与gradle文件的级别相同)。显然，我也在gradle文件中添加了相应的multiDexKeepFile和multiDexKeepProguard行，但是它没有改变任何东西。
我检查了我的APK的dex文件，但没有找到android.app.PictureInPictureParams。
我没什么办法解决我的问题。我应该怎样做呢？

让我用其他库(EventBus)解释一下，但是使用OP要求的相同上下文。在比奥利奥更少的android操作系统版本中，我得到了崩溃日志。
参考资料：https://github.com/greenrobot/EventBus/issues/595
关于同样的补充参考资料：
GreenBot的所有者也将FAQ更新为相同的：http://greenrobot.org/eventbus/documentation/faq/
导致错误的原因：如果类有一个参数不能用于设备的API级别的方法，则抛出异常。
示例：在APILevel21中添加了类PersistableBundle。随着新类的出现，在以PersistableBundle为参数的类活动中引入了一些新的生命周期方法，例如，onCreate (Bundle savedInstanceState, *PersistableBundle* persistentState)。现在，如果您覆盖此方法，并试图在旧设备上将此活动注册到EventBus，那么我们就有了所描述的导致错误的场景。
可能的建议：
- 也许您只是偶然地用PersistableBundle重写了一个生命周期方法。在这种情况下，只需更改为没有PersistableBundle的方法，例如onCreate (Bundle savedInstanceState)。
- 将EventBus 3与订阅服务器索引一起使用。这将避免反思，从而完全避免问题。作为一个积极的副作用，注册订阅者，从而应用程序启动时间将更快。
- 从订阅服务器类中删除违规方法。将事件处理程序方法提取到新的订阅服务器类中，或者将违规方法提取到非订阅服务器类中。
- 如果违规方法是公开的，则将其非公开。这是因为某些“计划b”逻辑EventBus应用的缘故: EventBus首先调用getDeclaredMethods，这将失败。接下来，EventBus将再次尝试使用getMethods (“计划b”)。后者将成功，因为getMethods只返回公共方法。但是，请记住，这是性能方面效率最低的方法(考虑到整个类的层次结构，在getMethods中使用2个反射调用而不是1个反射调用)。
对于我的问题建议#4，我使用了一个私有修饰符。
