Questions:
I’m attempting to have my Activity handle urls taking the form of mydomain.com or www.mydomain.com with both http and https schemes. Currently the IntentFilter attribute for my activity looks like this:
[IntentFilter(
new[] { Intent.ActionView },
Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
DataHost = "mydomain.com",
DataScheme = "http"
)]
Which generates this in the manifest, and doesn’t appear to be working for any of the required url configurations:
<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:host="mydomain.com" android:scheme="http" />
</intent-filter>
How can I change this attribute so that my activity will handle all urls of the form http(s)://(www.)mydomain.com ?
How to&Answers:
Compressed single IntentFilter:
[
IntentFilter
(
new[] { Intent.ActionView },
Categories = new[]
{
Intent.CategoryDefault,
Intent.CategoryBrowsable
},
DataSchemes = new[] { "http", "https" },
DataHosts = new[] { "*.xamarin.com", "xamarin.com" },
DataMimeType = "text/plain"
)
]
will generate following AndroidManifest.xml node:
<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:mimeType="text/plain" />
<data android:host="*.xamarin.com" />
<data android:host="xamarin.com" />
<data android:scheme="http" />
<data android:scheme="https" />
</intent-filter>
Answer：
You can add multiple intent filter attributes
[IntentFilter(
new[] { Intent.ActionView },
Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
DataHost = "mydomain.com",
DataScheme = "http"
)]
[IntentFilter(
new[] { Intent.ActionView },
Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
DataHost = "mydomain.com",
DataScheme = "https"
)]
[IntentFilter(
new[] { Intent.ActionView },
Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
DataHost = "*.mydomain.com",
DataScheme = "http"
)]
[IntentFilter(
new[] { Intent.ActionView },
Categories = new[] { Intent.CategoryDefault, Intent.CategoryBrowsable },
DataHost = "*.mydomain.com",
DataScheme = "https"
)]
public class MyActivity : Activity {}
the resulting xml will be
<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:host="mydomain.com" android:scheme="http" />
</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:host="mydomain.com" android:scheme="https" />
</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:host="*.mydomain.com" android:scheme="http" />
</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:host="*.mydomain.com" android:scheme="https" />
</intent-filter>
