问题描述

我有一个始终在后台运行的服务，有没有办法可以在我的服务中捕获NDEF_DISCOVERED意向过滤器?这样，当我的两个设备准备就绪时，就可以在服务中捕获该代码并根据需要进行操作吗?

I have a service which is always running in the background, is there a way that I can catch an NDEF_DISCOVERED intent filter in my service? So that once my two devices are ready to beam I can catch that code in a service and manipulate it as I need too?

推荐答案

NFC意图，即

• android.nfc.action.NDEF_DISCOVERED，
• android.nfc.action.TECH_DISCOVERED和
• android.nfc.action.TAG_DISCOVERED，

仅发送给活动.因此，您不能直接从服务中捕获它们.但是，您可以让该意图启动一个活动，然后该活动将调用该服务.

are only sent to activities. Thus, you cannot catch them from a service directly. However, you could let the intent launch an activity, which then invokes the service.
