Question

我正在使用Android 7.0中的新DirectBoot功能，我正在尝试确定手机在重启和直接启动模式后何时仍处于锁定状态。为此，我实现了一个我在Manifest中定义的BroadcastReceiver。

我的理解是，当手机重新启动时，它会在完成启动时但在用户输入其PIN之前发出ACTION_LOCKED_BOOT_COMPLETED广播。当输入PIN并且电话解锁时，发送ACTION_BOOT_COMPLETED广播。如果我将其intent-filter定义为ACTION_BOOT_COMPLETED，我的Receiver工作正常，但是一旦我添加LOCKED_BOOT_COMPLETED，我就会在重新启动手机时收到这样的致命错误消息，说它无法实例化我的接收器：

let valueDictionary:[String:String] = ["type":"work", "value":"updatetest@test.info"]
let fieldDictionary:[String:Any] = ["email":valueDictionary, "title":"r5-d5"]

let updateItemRequest = PKTItemsAPI.requestToUpdateItem(withID: 383626238, fields: fieldDictionary, files: nil, tags: nil)

PKTClient.current().perform(updateItemRequest).onComplete { response, error in
  if error == nil {
    print("Completed update!")
  } else {
    print("Error updating item.")
  }
}

我不确定为什么只有将我的Receiver的intent-filter从BOOT_COMPLETED更改为LOCKED_BOOT_COMPLETED时才会出现此问题。下面是我的Manifest不起作用（但是，如果我将intent-filter更改为BOOT_COMPLETED，应用程序不会崩溃，接收器工作完全正常！）：
