问题
I am trying to add deeplinking feature to my project.
My code in Androidmanifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.companyname.sample">
<uses-sdk android:minSdkVersion="15" />
<application android:label="sample.Android">
<activity android:icon="@drawable/icon" android:name="sample.Droid.MainActivity" android:label="sample">
<intent-filter>
<data android:scheme="http" android:host="www.sample.com" android:pathPrefix="/code" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
</application>
</manifest>
Mainactivity.cs
using Android.App;
using Android.Content.PM;
using Android.OS;
namespace sample.Droid
{
[Activity(Label = "sample", Icon = "@drawable/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate(Bundle bundle)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
LoadApplication(new App());
}
}
}
Here is the sample url I am using http://www.sample.com/code/hi
When I tap on this url I am getting the following Exception:
