gistfile1.txt

Android:

In your MainActivity:
Call run on InstallEventTask

public static class InstallEventTask extends AsyncTask<Void, Void, Void> {

    private static final String SHARED_PREFERENCE_FILE = "com.urbanairship.first_run";
    private static final String FIRST_RUN = "first_run";
    private final SharedPreferences sharedPreferences;
    private final Context context;

    public InstallEventTask(Context context) {
        this.context = context.getApplicationContext();
        this.sharedPreferences = context.getSharedPreferences(SHARED_PREFERENCE_FILE, Context.MODE_PRIVATE);
    }

    @Override
    protected Void doInBackground(Void... voids) {
        if (!sharedPreferences.getBoolean(FIRST_RUN, true)) {
            return null;
        }

        String advertisingId = null;
        boolean limitedAdTrackingEnabled = false;

        switch (UAirship.shared().getPlatformType()) {
            case UAirship.AMAZON_PLATFORM:
                advertisingId = Settings.Secure.getString(context.getContentResolver(), "advertising_id");
                limitedAdTrackingEnabled = Settings.Secure.getInt(context.getContentResolver(), "limit_ad_tracking", -1) == 0;
                break;

            case UAirship.ANDROID_PLATFORM:
            default:
                if (!PlayServicesUtils.isGoogleAdsDependencyAvailable()) {
                    break;
                }

                try {
                    AdvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(context);
                    if (adInfo == null) {
                        break;
                    }

                    advertisingId = adInfo.getId();
                    limitedAdTrackingEnabled = adInfo.isLimitAdTrackingEnabled();
                } catch (IOException | GooglePlayServicesNotAvailableException | GooglePlayServicesRepairableException e) {
                    Logger.error("Failed to generate first run event.");
                    break;
                }

                break;
        }

        CustomEvent.Builder eventBuilder = new CustomEvent.Builder("install");

        if (advertisingId != null) {
            eventBuilder.addProperty("idfa", advertisingId)
                        .addProperty("limited_ad_tracking_enabled", limitedAdTrackingEnabled);

        }

        eventBuilder.create().track();

        sharedPreferences.edit()
                         .putBoolean(FIRST_RUN, false)
                         .apply();
        return null;
    }

    public static void run(Context context) {
        new InstallEventTask(context).executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
    }
}

iOS:

Add the following to your Appdelegate's didLaunchWithOptions:

Obj-C:
@import AdSupport;

if ([[NSUserDefaults standardUserDefaults] valueForKey:@"com.urbanairship.install"] == false) {
    [[NSUserDefaults standardUserDefaults] setValue:@"install event has been added" forKey:@"com.urbanairship.install"];
    UACustomEvent *event = [UACustomEvent eventWithName:@"install"];
    [event setStringProperty:[[ASIdentifierManager sharedManager].advertisingIdentifier UUIDString] forKey:@"idfa"];
    [event setBoolProperty:[ASIdentifierManager sharedManager].isAdvertisingTrackingEnabled forKey:@"limited_ad_tracking_enabled"];
    [[UAirship shared].analytics addEvent:event];
}

Swift:
import AdSupport

if (UserDefaults.standard.value(forKey: "com.urbanairship.install") != nil) {
    UserDefaults.standard.setValue("install event has been added", forKey: "com.urbanairship.install")
    let event = UACustomEvent(name: "install")
    event.setStringProperty(ASIdentifierManager.shared().advertisingIdentifier.uuidString, forKey: "idfa")
    event.setBoolProperty(ASIdentifierManager.shared().isAdvertisingTrackingEnabled, forKey: "limited_ad_tracking_enabled")
    UAirship.shared().analytics.add(event)
}
