android - 什么是后台推送通知？安卓、 Urban Airship

Question

在扩展Urban Airship类BaseIntentReceiver时有一个方法叫做onBackgroundPushReceived，什么时候触发？

当应用程序在后台并且推送到达时，方法 onPushReceived 被调用。所以应用程序需要处于哪个状态才能触发 onBackgroundPushReceived ？还是后台推送和普通推送有什么不同？

Answer 1

来自他们的 documentation : onBackgroundPushReceived 在收到未导致发布通知的推送时调用。

protected abstract void onBackgroundPushReceived (Context context, PushMessage message)

Called when a push is received that did not result in a notification being posted.
