Android NDEF intent-filter with data for http scheme and host
I am trying to define an Intent filter that will only trigger when I receive NDEF messages that contain the URI of a particular web site.
I have it defined like this:
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:host="ta.bcntouch.com" />
</intent-filter>
But it won't trigger like that. I have also tried:
<data android:scheme="http"android:host="ta.bcntouch.com" />
With no luck. Also with just DEFAULT. Removing the element will cause it to 开发者_C百科trigger.
Can this be done? The Android documentation only shows examples using MIME type in the element.....
Any help appreciated.
Here is the filters I finally used, to capture a number of specific known URL combinations.
The '*' at the start of the host field allows me to use the same filter when testing with test servers that are in a sub-domain, or follow the same format for name.
The second (View) one captures the same URL formats from web-pages, emails, etc...:
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/p/.*" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/l/.*" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/a.*" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/t.*" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/p/.*" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/l/.*" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/a.*" />
<data android:scheme="http"
android:host="*ta.bcntouch.com"
android:pathPattern="/t/.*" />
</intent-filter>
This format works for me
<data android:scheme="http" android:host="www.domain.com" android:pathPattern=".*" />
I have done something similar, but I think you cannot use the uri. You need to write a MIME ndef message and assign the custom mime type like x-myapp/mydemo to your activity using the intent filter. you can then read any content, like a URL for example, and trigger a web browser for example.
