Issue
I am using Xamarin to develop an Android application. I want to be able to open the app when the user opens the link example://gizmos, so I add this to my manifest file:
<activity android:name="mynamespace.MyActivity"
android:label="@string/application_name" >
<intent-filter android:label="@string/application_name">
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<!-- Accepts URIs that begin with "http://www.example.com/gizmos” -->
<data android:scheme="http"
android:host="www.example.com"
android:pathPrefix="/gizmos" />
<!-- note that the leading "/" is required for pathPrefix-->
<!-- Accepts URIs that begin with "example://gizmos” -->
<data android:scheme="example"
android:host="gizmos" />
</intent-filter>
</activity>
This is taken directly from the Android documentation. I try to click on the link example://gizmos from the mail application on my physical Android device, but I get the message: Unable to find application to perform this action
EDIT
It is not the same as the suggested duplicate, they are not using Xamarin.
Solution
In Xamarin android the activity configuration is set in attribute of the activity class
For example:
namespace XamarinAndroidDeepLink
{
[Activity(Label = "XamarinAndroidDeepLink", MainLauncher = true, Icon = "@drawable/icon")]
[IntentFilter(new[] { Android.Content.Intent.ActionView },
DataScheme = "wori",
DataHost = "example.com",
DataPathPrefix ="/",
Categories = new[] { Android.Content.Intent.CategoryDefault,Android.Content.Intent.CategoryBrowsable })]
public class MainActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
}
}
}
And you do not need to set the intent filter in the Manifest the c# will help you to build the configuration in the manifest.
Test the deeplink by adb :
adb shell am start -W -a android.intent.action.VIEW -d "wori://example.com/?id=1234" XamarinAndroidDeepLink.XamarinAndroidDeepLink
You will find your app start :
Some Browser can not distinguish the url. They will add http:// before your customer url and when you input the url in the address bar it will using the search engine.
I suggest you to design you own html page and download google chrome to open the html page:
Note: Do not open the html page by html viewer
<html>
<head>
<title>Product 12345</title>
</head>
<body>
<a href="wori://example.com/?id=1234">lalala</a>
</body>
</html>
Download Google Chrome and open your link :
