使用NFC将android设备连接到wifi，无需任何第三方软件

Question

Is there a way to use nfc to connect an android device to a wifi.network without the use of a 3rd party application. Ie using the built in functionality of android and how it reads nfc tags.

I need a nfc tag to connect the phone / device to a specific WiFi.network and then download my application from that WiFi.network. How can I go about doing this?

I can achieve this with an app such as nfc launcher, but then a user would have to go install that app then go and swipe the nfc tag to download my app.

So for a use case:

I want to have a nfc tag at a sales counter or restaurants table. Then all a user has to do to get and install the app is scan the qr code.

I totally understand what you are trying to do here, and I am wanting to do the same thing myself. The best info I have got so far comes from this post

Share Wifi credentials via NFC tag without special apps

However, whilst this tells us there is a specification for NFC>WiFi handover, it appears it is not supported by Android.

I will keep searching and let you know if I come up with anything further.

I'm also looking for NFC>Bluetooth handover, but coming across similar barriers :-(

Why not just put a download link for your app on the NFC tag? If the device has an internet connection, tapping the tag will launch the browser (or the Google Play app) and follow the download link. It's not really up to you to demand that the device connects to a wifi network first.

I understand this question. Please take a look at the new NFC programmer provided by Google for devices >= Lollipop. I haven't delved into the details of this program myself but if there is a built-in support there, P2P tapping or tag read in order to program Wi-Fi details should get the slave peer device to obtain the required internet connection (simple WPA/WEP based SSID).

That way, when an internet connection is established, the slave could be instructed to download enabler apk from a remote source, such as PlayStore or internal private host server. However, PlayStore access would require that device be already equipped with a Google account (not possible on a factory reset device).

I think you want to achieve what these guys here provide: https://www.tenonedesign.com/porter

You hold your NFC-capable andoid mobile to it and it connects to your wifi. newer Iphones are shown a qr-code, SSID und password
