Tracking Uninstalls

Note: Uninstall tracking is only available to Enterprise customers.

Android Uninstall Tracking

To enable uninstall tracking for your Android app, first configure the app in the Singular platform as detailed in Setting Up Uninstall Tracking. Then follow the instructions below.

Note: Google deprecated the GCM APIs on April 2018. Use FCM for uninstall tracking.

Enabling Uninstall Tracking Using Firebase Cloud Messaging (FCM)

1. Integrate with FCM:

To track uninstalls, you can use the services of the Firebase Cloud Messaging (FCM) platform. If you are not already using FCM follow Google's instructions on how to Set up a Firebase Cloud Messaging client app on Android.

FCM Requirements (source)

FCM clients require devices running Android 4.1 or higher that also have the Google Play Store app installed, or an emulator running Android 4.1 with Google APIs. Note that you are not limited to deploying your Android apps through Google Play Store.

Users/devices who are not running on supported versions of Android will not be available for Singular uninstall tracking.

2. Update the AndroidManifest.xml File:

Update your AndroidManifest.xml file to add the necessary intent filter for your app (replace MyFirebaseMessagingService with your class that implements the Firebase Service):

<service android:name=".java.MyFirebaseMessagingService"
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter> </service> <service android:name=".java.MyFirebaseMessagingService" android:exported="false"> intent-filter> action android:name="com.google.firebase.MESSAGING_EVENT" /> </intent-filter> </service>

3. Register and Send the FCM Device Token:

Finally, set the FCM device token after your SingularConfig is initialized in OnCreate(), as follows:

Singular.setFCMDeviceToken(String fcmDeviceToken);

iOS Uninstall Tracking

Uninstall tracking on iOS is based on Apple push-notification technology. If your app doesn't currently support push notifications, see Apple's guide. If your app already supports push notifications, all you need to do is pass the device token returned from APNS using the RegisterDeviceTokenForUninstall method, after the SDK is initialized. 

SingularSDK.RegisterDeviceTokenForUninstall Method
Description Pass the device token returned from APNS. Note that the APNS token is usually binary data in the native form, but you need to pass it as a string.
public static void RegisterDeviceTokenForUninstall
(string APNSToken)
Usage Example
// pass the APNS token as a hex-string 

Adding Global Properties

The Singular SDK lets you define custom additional properties that you want to send to the Singular servers with every session and event sent from the app. These properties can represent any information you want about the user, the app mode or status, or anything else. Once you set these properties, they are available as dimensions in your reports and you can use them to break down your data.

For example, if you have a gaming app, you can define a property called "Level" and set it initially to "0". Any session and event sent from the app will be sent with "Level": "0". Once the user levels up you reset the property to "1" and so on. You can then get your reports, including sessions, event counts, and revenue data, broken down by user level.

  • You can define up to 5 global properties.
  • They persist between app runs (with the latest value you gave them) until you unset them or the user uninstalls the app.
  • Each property name and value can be up to 200 characters long. If you pass a longer property name or value, it will be truncated to 200 characters.

Setting Global Properties before Initialization

You can use the SetGlobalProperty method to set global properties through SingularSDK before initializing the SDK. Make sure to turn off the `Initialize On awake` flag if you want your global properties to be included in the session. 

Note that since global properties and their values persist between app runs, the property that you are setting may already be set to a different value. Use the overrideExisting parameter to tell the SDK whether to override an existing property with the new value or not.

Setting Global Properties After Initialization

Use the following methods to set, unset, and retrieve global properties at any time in the app's run.

SingularSDK.SetGlobalProperty Method

Set a global property to a given value.


  • If the property does not exist yet, and there are already 5 other global properties, the property will not be added.
  • If the property has already been set, the overrideExisting parameter determines whether the existing value will be overridden.
  • The method returns true if the property was set successfully or false otherwise.
Signature public static bool SetGlobalProperty(string key, string value, bool overrideExisting)
Usage Example
bool result = SingularSDK.SetGlobalProperty("key", "value", false);
SingularSDK.GetGlobalProperties Method
Description Retrieve all the global properties and their current values as a Map.
Signature public static Dictionary<string, string> GetGlobalProperties()
Usage Example
Dictionary<string, string> props = SingularSDK.GetGlobalProperties();
SingularSDK.UnsetGlobalProperty Method
Description Remove a global property.
Signature public static void UnsetGlobalProperty(string key)
Usage Example
SingularSDK.ClearGlobalProperties Method
Description Remove all global properties.
Signature public static void ClearGlobalProperties()
Usage Example

GDPR Compliance

The Singular SDK provides several methods to help you comply with GDPR policies and let Singular know about user consent or non-consent for tracking.

SingularSDK.TrackingOptIn Method
Description Notify Singular of user consent (opt-in) for tracking.
Usage Example
SingularSDK.TrackingUnder13 Method
Description Notify Singular that a user is a minor (under 13).
Usage Example
SingularSDK.StopAllTracking Method
Description Stop all tracking activities for this user on this app.
Note: Calling this method effectively disables the SDK, even after the app restarts (the state is persistent)! The only way to re-enable tracking is by calling resumeAllTracking().
Usage Example
SingularSDK.ResumeAllTracking Method
Description Resume tracking for this user on this app.
Usage Example
SingularSDK.IsAllTrackingStopped Method
Description Check the tracking status for this user on this app. Returns true if tracking has been stopped using StopAllTracking() and not resumed.
Usage Example
