Xamarin Configuration
Integrate the Branch SDK into the iOS and Android components of your Xamarin app.
iOS
iOS 14 Implementation
In order to give you full control over the user experience, the Branch SDK will not trigger the IDFA permission modal.
However, we will still collect and use IDFAs when available if you do choose to trigger the modal.
Inconsistent Universal links behavior on iOS 11.2
After updating a device to iOS 11.2, we found that the app's AASA file is no longer downloaded reliably onto your user’s device after an app install. As a result, clicking on Universal links will no longer open the app consistently. You can set forced uri redirect mode on your Branch links to open the app with URI schemes. View details of the issue on the Apple Bug report.
1. Configure Branch Dashboard
Start by configuring the iOS settings of your Xamarin application in the Branch Dashboard:
- On the Link Settings page, check the I have an iOS App checkbox.
- Enter the app's URI Scheme in the iOS URI Scheme field. For an app with the URI Scheme
testiosapp
, the entry would be:testiosapp://
. - Enter the app's Apple Store name in the Apple Store Search field. If the app is not yet available on the App Store, select Custom URL and enter as a placeholder the URL of an appropriate web site (the exact site does not matter).
- Check the Enable Universal Links checkbox.
- Enter the app's case-sensitive Bundle Identifier, as well as Apple App Prefix as shown on the Apple Developer Portal.
2. Install Branch NuGet Package
IMPORTANT: Xamarin applications should use versions 8.1.2 or lower of the Branch-Xamarin-Linking-SDK
NuGet package - versions 9.0.0+ are for MAUI applications.
The package must be added to each of the Xamarin projects that will use Branch methods.
To add the Branch NuGet package to a project:
- Right-click on each project and select Add → Add NuGet Packages.
- Find the
Branch-Xamarin-Linking-SDK
package and add it to the project. Make sure you are using version 8.1.2 or lower for a Xamarin application.
3. Configure App
Create an Apple Device Provisioning Profile for the App
- Open Xcode and create a new project with the same name as your Xamarin iOS project.
- On the Xcode project's General tab, verify the app's case-sensitive Bundle Identifier is correct and select the appropriate Team. Be sure to resolve any errors here.
- Select the Capabilities tab and enable the Associated Domains entitlement.
- Create
applinks:
entries for the Branch link domain and the alternate link domain (the link domain can be found at the bottom of the Branch Dashboard's Link Settings page). For example, the entries for an app with the default link domaintestiosapp.app.link
would be:
applinks:testiosapp.app.link
applinks:testiosapp-alternate.app.link
- Use Xcode to run this newly-created app on an iOS device. This will create and install a Provisioning Profile with the proper entitlements on that device.
Configure the Xamarin Project's Info.plist File
- Open the
Info.plist
file. - Enter the app's Bundle Identifier from the Apple Developer Portal in the Bundle Identifier field. IMPORTANT: This field will automatically be populated with an all-lowercase value by Xamarin. The value is in fact case-sensitive and must match the value in the Apple Developer Portal precisely.
- Click on the Advanced tab.
- In the URL Types section, click the Add URL Type button:
Identifier: Branch Scheme
URL Schemes: The app's URI Scheme, for exampletestiosapp
Role: Editor
Configure the Xamarin Project's Associated Domains Entitlement
- Open the
Entitlements.plist
file and browse to the Associated Domains section. - Create entries for both the app's link domain and its alternate link domain. The entries for the
TestBed-Xamarin
app would be:
applinks:testiosapp.app.link
applinks:testiosapp-alternate.app.link
Update the Project's Signing Identity and Provisioning Profile
- Right-click on the iOS project and select Options.
- Select iOS Bundle Signing.
- Set the Signing Identity and Provisioning Profile values to the values used when deploying the Provisioning Profile to the device.
4. Initialize Branch
Branch initialization occurs within the FinishedLaunching
method of the AppDelegate.cs
file. Branch calls are also required in the OpenUrl
, ContinueUserActivity
, and ReceiveRemoteNotification
methods to ensure that Branch link information is handled properly whenever the app becomes active.
Whenever the app becomes active, the Branch SDK will reach out to the Branch backend to retrieve any available link parameters. If the app becomes active due to a click on a Branch link, the link data will be returned in the InitSessionComplete
method. This is where any Branch Deep Link routing logic should reside. Any error in retrieving Branch link data from the backend will be returned in the SessionRequestError
method.
// AppDelegate.cs
using Foundation;
using UIKit;
using BranchXamarinSDK;
using BranchXamarinSDK.iOS;
using System;
namespace TestiOSApp.iOS
{
[Register("AppDelegate")]
public class AppDelegate : UIApplicationDelegate, IBranchBUOSessionInterface
{
public override UIWindow Window
{
get;
set;
}
public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
// Debug mode - set to 'false' before releasing to production
BranchIOS.Debug = true;
BranchIOS.Init("key_live_<YOUR-GUID-HERE>", launchOptions, this);
return true;
}
// Called when the app is opened via URI scheme
public override bool OpenUrl(UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
{
return BranchIOS.getInstance().OpenUrl(url);
}
// Called when the app is opened from a Universal Link
public override bool ContinueUserActivity(UIApplication application, NSUserActivity userActivity,
UIApplicationRestorationHandler completionHandler)
{
return BranchIOS.getInstance().ContinueUserActivity(userActivity);
}
// Called when the app receives a push notification
public override void ReceivedRemoteNotification(UIApplication application, NSDictionary userInfo)
{
BranchIOS.getInstance().HandlePushNotification(userInfo);
}
// Called when the Branch initialization is completed
// Put Branch Deep Link logic in this method
public void InitSessionComplete(BranchUniversalObject buo, BranchLinkProperties blp)
{
NSObject[] keys = {
NSObject.FromObject("+is_first_session")
};
NSObject[] values = { NSObject.FromObject(0) };
if (buo.metadata.ContainsKey("+is_first_session"))
{
values[0] = NSObject.FromObject(buo.metadata["+is_first_session"]);
}
NSDictionary nsData = NSDictionary.FromObjectsAndKeys(values, keys);
}
// Called when there is an error initializing Branch
public void SessionRequestError(BranchError error)
{
Console.WriteLine("Branch error: " + error.ErrorCode);
Console.WriteLine(error.ErrorMessage);
}
}
}
Create a Class for Branch Session Handling
Branch initializes asynchronously, with Branch link parameters being returned following a network call to Branch. If initialization is successful, the InitSessionComplete
method will be invoked. If initialization is unsuccessful, the SessionRequestError
method will be invoked. Branch Deep Link routing logic should be located in the InitSessionComplete
method.
- Right-click on the C# project and select Add → New File.
- Select General, then Empty Class.
- Rename the file to
TestXamarinFormsApp.cs
. - Add the following code:
using BranchXamarinSDK;
using System.Collections.Generic;
using System.ComponentModel;
using Xamarin.Forms;
// Replace `TextXamarinFormsApp` with actual name of your app
namespace TestXamarinFormsApp
{
public class TestXamarinFormsApp : Application, IBranchSessionInterface
{
public TestXamarinFormsApp()
{
}
#region IBranchSessionInterface implementation
public void InitSessionComplete(Dictionary<string, object> data)
{
}
public void CloseSessionComplete()
{
}
public void SessionRequestError(BranchError error)
{
}
#endregion
}
}
Create a Class for Handling Link Data
Branch stores link data in an object referred to as the Branch Universal Object, or BUO.
- Right-click on the C# project and select Add → New File.
- Select General → Empty Class.
- Rename the file to
TestXamarinFormsAppBUO.cs
. - Add the following code:
using BranchXamarinSDK;
using System.Collections.Generic;
using System.ComponentModel;
using Xamarin.Forms;
// Replace `TextXamarinFormsApp` with actual name of your app
namespace TestXamarinFormsApp
{
public class TestXamarinFormsAppBUO : Application, IBranchBUOSessionInterface
{
public TestXamarinFormsAppBUO()
{
}
#region IBranchBUOSessionInterface implementation
public void InitSessionComplete(BranchUniversalObject buo, BranchLinkProperties blp)
{
}
public void SessionRequestError(BranchError error)
{
}
#endregion
}
}
Add Branch Calls to the AppDelegate
To ensure that the Branch SDK initializes when the app starts and can retrieve link parameters whenever the app becomes active, Branch initialization occurs within the FinishedLaunching
method of the AppDelegate.cs
file. Branch calls are also required in the OpenUrl
, ContinueUserActivity
, and ReceiveRemoteNotification
methods to ensure that Branch link information is handled properly whenever the app becomes active. The AppDelegate.cs
file should look like this:
using System;
using System.Collections.Generic;
using System.Linq;
using Foundation;
using UIKit;
using BranchXamarinSDK;
using TestXamarinFormsApp;
// Replace `TextXamarinFormsApp` with actual name of your app
namespace TestXamarinFormsApp.iOS
{
[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
// Debug mode - set to 'false' before releasing to production
BranchIOS.Debug = true;
TestXamarinFormsAppBUO appBUO = new TestXamarinFormsAppBUO();
// Find your key_live value on the Account Settings page of the Branch Dashboard
BranchIOS.Init("key_live_<YOUR-GUID-HERE>", options, appBUO);
LoadApplication(appBUO);
return base.FinishedLaunching(app, options);
}
// Called when the app is opened via URI scheme
public override bool OpenUrl(UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
{
return BranchIOS.getInstance().OpenUrl(url);
}
// Called when the app is opened from a Universal Link
public override bool ContinueUserActivity(UIApplication application, NSUserActivity userActivity, UIApplicationRestorationHandler completionHandler)
{
return BranchIOS.getInstance().ContinueUserActivity(userActivity);
}
// Called when the app receives a push notification
public override void ReceivedRemoteNotification(UIApplication application, NSDictionary userInfo)
{
BranchIOS.getInstance().HandlePushNotification(userInfo);
}
}
}
Android
Google Play Services version 17+
If you reference Google Play Services version 17 or higher, you MUST complete Google's update instructions here.
Due to a major Google Play Services change made in June 2019, not completing the update steps will cause Branch's Android SDK (and various other cross-platform SDKs, e.g. Unity) to stop collecting Android AID which we use to ensure accurate deep linking and attribution.
If you are running Google Play Services versions below 17, no update is necessary.
1. Configure Branch Dashboard
Start by configuring the Android settings of your Xamarin application in the Branch Dashboard.
2. Install Branch NuGet Package
Google Advertising Identifier (GAID)
Branch Xamarin SDK 8.0.0+ requires the
Xamarin.GooglePlayServices.AdsIdentifier
NuGet package to obtain the advertising id.Note that version 117.0.1.5 does not work properly on Visual Studio for Mac 2019, use 117.0.1.3 instead.
IMPORTANT: Xamarin applications should use versions 8.1.2 or lower of the Branch-Xamarin-Linking-SDK
NuGet package - higher versions are for MAUI applications.
The package must be added to each of the Xamarin projects that will use Branch methods.
To add the Branch NuGet package to a project:
- Right-click on each project and select Add → Add NuGet Packages.
- Find the
Branch-Xamarin-Linking-SDK
package and add it to the project. Make sure you are using version 8.1.2 or lower for a Xamarin application.
3. Configure App
Ensure Android Project Is Not Using Shared Mono Runtime
- Right-click on the Android project and select Options.
- Select Android Build.
- On the General tab, un-check Use Shared Mono Runtime.
Add App Capabilities in Manifest File
In the Required permissions
section of AndroidManifest.xml
, configure the following permissions:
AccessNetworkState
Internet
Additional reading on the Android manifest:
Add App's Branch Key
Add the app's Branch key to the Android project's Strings.xml
file which lives in Resources/values/
. This file contains values that can be accessed by the app's Application class.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">TestXamarinFormsApp</string>
<string name="branch_key">key_live_liAnF8k7gZUEZv76Rt9a4bffAzlC5zVW</string>
</resources>
4a. Initialize Branch Without Xamarin.Forms
You can initialize Branch with or without the Xamarin.Forms framework.
To initialize without the framework:
- Right-click on the .Droid project and select Add → New File.
- Select General → Empty File.
- Name the file
Application.cs
. - Add the following code:
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using BranchXamarinSDK;
// Replace `TestAndroidApp` with actual name of your app
namespace TestAndroidApp.Droid
{
[Application(AllowBackup = true, Icon = "@mipmap/icon", Label = "@string/app_name")]
[MetaData("io.branch.sdk.auto_link_disable", Value = "false")]
[MetaData("io.branch.sdk.TestMode", Value = "true")]
[MetaData("io.branch.sdk.BranchKey", Value = "@string/branch_key")]
public class TestAndroidApp : Application
{
public TestAndroidApp(IntPtr javaReference, JniHandleOwnership transfer) : base(javaReference, transfer)
{
}
public override void OnCreate()
{
base.OnCreate();
BranchAndroid.GetAutoInstance(this.ApplicationContext);
}
}
}
Key | Value |
---|---|
io.branch.sdk.TestMode | Setting this parameter to true enables Debug Mode, which causes simple uninstall/reinstalls of the app to trigger Install events. Be sure to disable this before deploying to production. Note that enabling Debug Mode on iOS also forces the app to use the Branch test key if this key has been added to the project. Apps running with a test key will be unable to receive data from Branch Deep Links created with the live key. |
io.branch.sdk.BranchKey | The app's Branch key. Both a live key and a test key can be added to the Strings.xml file. When test mode is enabled, the app will automatically use the test key if one has been specified. |
Create an Activity to Handle Branch Events
- Right-click on the .Droid project and select Add → New File.
- Select Android →Activity.
- Rename the file
BranchActivity.cs
. - Add the following code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Newtonsoft.Json;
using BranchXamarinSDK;
using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
// Replace `TestAndroidApp` with actual name of your app
namespace TestAndroidApp.Droid
{
[Activity(Label = "BranchActivity")]
public class BranchActivity : Activity
{
private string logString = "";
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
LogMessage("Branch initialization completed: ");
Dictionary<string, object> data = JsonConvert.DeserializeObject<Dictionary<string, object>>(Intent.GetStringExtra("BranchData"));
foreach (var key in data.Keys)
{
LogMessage(key + " : " + data[key].ToString());
}
}
#region Utils
void LogMessage(string message)
{
Console.WriteLine(message);
logString += DateTime.Now.ToLongTimeString() + "> " + message + "\n";
}
#endregion
}
}
Create an Activity to Handle Branch Errors
- Right-click on the .Droid project and select Add → New File.
- Select Android → Activity.
- Rename the file
BranchErrorActivity.cs
. - Add the following code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
// Replace `TestAndroidApp` with actual name of your app
namespace TestAndroidApp.Droid
{
[Activity(Label = "BranchErrorActivity")]
public class BranchErrorActivity : Activity
{
private string logString = "";
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
LogMessage("Branch initialization failed");
LogMessage("Error code: " + Intent.Extras.GetInt("ErrorCode").ToString());
LogMessage(Intent.Extras.GetString("ErrorMessage"));
}
#region Utils
void LogMessage(string message)
{
Console.WriteLine(message);
logString += DateTime.Now.ToLongTimeString() + "> " + message + "\n";
}
#endregion
}
}
Initialize Branch and Configure Branch Session Management
Branch must be initialized in the OnCreate
method of either the Application
class or the first Activity launched by the app. The OnNewIntent
method must be added to retrieve the latest link identifier when the app becomes active due to a Branch Deep Link click.
If initialization is successful, the InitSessionComplete
method will be invoked. If initialization is unsuccessful, the SessionRequestError
method will be invoked. Branch Deep Link routing logic should be located in the InitSessionComplete
method.
In the code example below the following Branch initialization and session management steps have been added to MainActivity.cs
:
- An Activity to respond to the app's URI Scheme is created and launched in
singleTask
mode. - The
OnCreate
method is overwritten and initializes the Branch SDK. - The
OnNewIntent
method is overwritten. - An
InitSessionComplete
method is added for processing Branch Deep Link information. This is where Deep Link routing logic should live. - A
SessionRequestError
method is added to handle situations where Branch fails to initialize.

public void InitSessionComplete(Dictionary<string, object> data)
{
//Handle custom logic based on deep link data in InitSessionComplete
//View all the link data in the console
Console.WriteLine("My Link Data: " + JsonConvert.SerializeObject(data));
//Preferred method: use BranchActivity created previously to handle the link data
//Will need to update BranchActivity with desired custom logic, to open the correct page in the app
var intent = new Intent(this, typeof(BranchActivity));
intent.PutExtra("BranchData", JsonConvert.SerializeObject(data));
StartActivity(intent);var intent = new Intent
}
public void SessionRequestError(BranchError error)

Troubleshoot
iOS
Deep Link Testing
To test whether your app is properly configured to support Branch Deep Links:
- Create a Branch Deep Link on the Branch Marketing Dashboard.
- Delete your app from your test device.
- Compile your app with Xcode.
- Paste the Branch Deep Link in the device's Apple Notes app.
- Long press on the Branch Deep Link (not 3D Touch).
- Click Open in to open your app.
NuGet Package Failures
Adding required NuGet packages to the C# project may fail if the project has not been configured to use PCL 4.5 - Profile78. To solve this:
- Right-click on the project name and select Options.
- Browse the menu to Build → General.
- Change the Current Profile to PCL 4.5 - Profile78 and try again.
Provisioning Profile Failures
Xamarin automatically populates the Bundle Identifier field in the Info.plist
file with an all-lowercase value derived from the app's name. This value is in fact case-sensitive and must match the value in the Apple Developer Portal precisely. The default Xamarin configuration may work when there are no entitlements configured, and then suddenly begin failing after entitlements have been added.
This issue can be resolved by ensuring that the Bundle Identifier in the Info.plist
matches the Bundle Identifier shown on the Apple Developer Portal. To make this change:
- Open the
Info.plist
file. - Enter the app's Bundle Identifier from the Apple Developer Portal in the Bundle Identifier field.
Android
Deep Link Testing
To test whether your app is properly configured to support Branch Deep Links:
- Create a Branch Deep Link on the Branch Marketing Dashboard.
- Delete your app from your test device.
- Compile your app with Android Studio.
- Paste the Branch Deep Link in the device's Google Hangouts app.
- Click on the Branch Deep Link.
Linking Errors During Build
The Newtonsoft.Json
NuGet package is automatically added to a project when the Branch-Xamarin-Linking-SDK
package is added. There is a known issue with this package that results in linking errors when building a project:
error XA0009: Error while loading assembly: /Users/david/Projects/TestXamarinFormsApp/Droid/obj/Debug/android/assets/mscorlib.dll
To resolve this issue:
- Right-click on the project and select Options.
- Go to Android Build and select the Linker tab.
- Select Release.
- Go to the Ignore Assemblies box.
- Add System.Core to the assemblies.
- Rebuild the app.
