SyncAdapter 与 JobScheduler
SyncAdapter vs JobScheduler
排除 JobScheduler 仅支持 API > 21 的事实 - JobSchedulers 是否旨在完全取代 SyncAdapters？或者 SyncAdapter 是否包含 JobScheduler 缺少的任何功能？
我的用例是每隔几个小时同步一次 RSS 提要。这可以通过 JobScheduler 实现 - 对吗？
我会说 JobScheduler 不是 SyncAdapter 的直接替代品，后者具有更专业的用途（在设备和服务器之间传输数据）。另一方面，JobScheduler 用于安排在未来某个时间点执行的任务 - 就像 AlarmManager - 但具有更广泛的潜力。
顺便说一句，有人试图 backport JobScheduler。
SyncAdapter
The framework continues to provide the SyncAdapter class for managing tasks that sync data between the device and a server. Sync adapters are designed specifically for syncing data between a device and the cloud; you should only use them for this type of task. Sync adapters are more complex to implement than the libraries and APIs mentioned above, because they require at least a fake authenticator and content provider implementation. For these reasons, you typically should not create a sync adapter just to sync data to the cloud in the background. Wherever possible, you should instead use JobScheduler, Firebase JobDispatcher, or GCM Network Manager .
In Android N (API level 24), the SyncManager sits on top of the JobScheduler. You should only use the SyncAdapter class if you require the additional functionality that it provides.
