Firestore脱机写入/添加不起作用-FirestoreOfflineWrite/AddNotWorking

-2  

You can't simply write data offline because Firestore can get the data and upload it whenb you have an Internet connection (which requires a task going in the background). Firestore has improved its offline capabilities but you can always choose to create your own service to upload it when the device connects.

您不能简单地离线写入数据，因为Firestore可以获取数据并在您拥有Internet连接时上传数据（这需要在后台执行任务）。 Firestore已经改进了其离线功能，但您始终可以选择创建自己的服务，以便在设备连接时上传它。

Android lets you create Services. From developer.android.com:

Android允许您创建服务。来自developer.android.com：

A service is a component that runs in the background to perform long-running operations or to perform work for remote processes. A service does not provide a user interface. For example, a service might play music in the background while the user is in a different application, or it might fetch data over the network without blocking user interaction with an activity. Another component, such as an activity, can start the service and let it run or bind to it in order to interact with it. A service is implemented as a subclass of Service.

服务是在后台运行以执行长时间运行操作或执行远程进程工作的组件。服务不提供用户界面。例如，当用户在不同的应用程序中时，服务可能在后台播放音乐，或者它可能通过网络获取数据而不阻止用户与活动的交互。另一个组件（如活动）可以启动服务并让它运行或绑定到它以与之交互。服务是作为服务的子类实现的。

So you could create a Service which keeps waiting for an Internet connection and just calls the FirebaseFirestore object to upload all the data you want.

因此，您可以创建一个等待Internet连接的服务，只需调用FirebaseFirestore对象即可上传所需的所有数据。
