Hybrid solutions and the FollowAnalytics SDK

Note that if you are working on a hybrid non-native solution, you will have to do some of the procedures on the native side of your app. This will be the case for OS specific as well as more advanced features. When this is necessary, we will provide the information for each platform. Each FollowAnalytics SDK for PhoneGap/Cordova are based on a native version of the SDK.


The FollowAnalytics PhoneGap/Cordova SDK was tested on :

  • Cordova CLI v7.0.1
  • Cordova platform android v7.0.0
  • Cordova platform iOS v4.5.0


This document will cover app setup and the component installation process, as well as basic integration steps for iOS and Android.

If you want an example, check out our PhoneGap sample integration code on Github.

Prerequisites and minimal setup

In this section, we explain how to get started with FollowAnalytics SDK for iOS. Before you start, be sure to have all the necessary prerequisites. These include:

  • Registering the application on the Platform
  • Generating the API Key

Here are the minimal steps for integrating the SDK in your app:

Once the integration is finished, we highly recommend you test the setup. You will find out how to test your setup in this section. Then, you can start tagging events and saving attributes in your app.


  1. Download the FollowAnalytics SDK from the developer portal.

  2. Add the FollowAnalytics SDK plugin to your cordova project:

    cordova plugin add "/path/to/fa-sdk-phonegap-plugin/"


  1. Remove the old version of the plugin from your project:

    cordova plugin rm cordova.plugin.followanalytics
  2. Download the new version of the plugin and add it to your project:

    cordova plugin add "/path/to/fa-sdk-phonegap-plugin/"
  3. Run cordova prepare ios and cordova prepare android to apply the new plugin changes.

Initialize the SDK

Be sure to have your API key

Be sure to have your API key for this step of the configuration. You can retrieve you app's API key from the administration section of the FollowAnalytics platform (see here)

Add FollowAnalytics Phonegap SDK plugin

Be sure to add FollowAnalytics Phonegap SDK plugin in your cordova project by following the Installation tutorial. This action will create some default configuration in your cordova project that affects the initialization of FollowAnalytics Phonegap SDK.

FollowAnalytics Phonegap SDK plugin will generate, if not available yet, a followanalytics_configuration.json file at your root directory of your cordova project:

  |--- config.xml
  |--- followanalytics_configuration.json // <-
  |--- hooks/
  |--- node_modules/
  |--- package-lock.json
  |--- package.json
  |--- platforms/
  |--- plugins/
  |--- www/

This file holds information for initializing FollowAnalytics Phonegap SDK.

You will need to change the content of this file for customising the initialization of FollowAnalytics Phonegap SDK.

For instance :

  "android" :
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : true,
      "maxBackgroundTimeWithinSession" : 120 
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : false,
      "maxBackgroundTimeWithinSession" : 120 
  "ios" :
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : true,
      "maxBackgroundTimeWithinSession" : 120 
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : false,
      "maxBackgroundTimeWithinSession" : 120 

You can also add custom build variants in both platforms like this:

      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : true,
      "maxBackgroundTimeWithinSession" : 120 
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : false,
      "maxBackgroundTimeWithinSession" : 120 
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : true,
      "maxBackgroundTimeWithinSession" : 120 

Use cordova prepare <platform>

Apply the changes on followanalytics_configuration.json running cordova prepare android for Android or cordova prepare ios for IOS.

Below, a description table that FollowAnalytics Phonegap SDK accepts as properties to add for customizing the initialization :

Properties Availability Type Default Value Description
apiKey Required string null Your app api key to use our SDK
isVerbose Optional boolean false To see internal logs made by the SDK
maxBackgroundTimeWithinSession Optional number 120 To determine the lifetime of a session when in background (between 15 and 3600)
apiMode Optional string PROD To set your API Mode to prodution or develop (PROD or DEV)
archiveInAppMessages Optional boolean false true to archive InApp campaigns messages
archivePushMessages Optional boolean false true to archive Push campaigns messages
appGroup Optional string undefined An app group identifier to link the extension target the app

Properties in android platform

Be sure to add any properties inside of "android" json object. Otherwise the properties won't be affected to the initialization of FollowAnalytics Phonegap SDK.

Change build variant

The built variant will be the same as the configuration of the app.iml. If the file as not found, the build variant will be set to debug.

If you got an error like Program type already present: android.support.v4... at build

To fix that, use AndroidX in your project. To do so, go to gradle.properties and add this:


Properties in ios platform

Be sure to add any properties inside of "ios" json object. Otherwise the properties won't be affected to the initialization of FollowAnalytics Phonegap SDK.

Change build variant

To choose what build variant you want to use in IOS you need to create a new environment variable called FA_CONFIGURATION with value NameOfYourBuild. If FA_CONFIGURATION was not found, the plugin will try to use the properties on the release variant else will use the first value on the JSON.

Register for notifications


Push notifications on debug mode don't work. If you wish to test your notifications, which is highly recommended, switch to release mode.

Android and Firebase Cloud Messaging

Get started with Firebase

Sending push notifications for Android requires Firebase Cloud Messaging, Google's standard messaging service. If you don't already use Firebase, you will need to do the following:

  • Create Firebase project to Firebase console

Before you start adding Firebase to your project, we recommend you take the time to familiarize yourself with firebase and its console. You will find this information (and much more) by referring to the Google documentation.

FollowAnalytics SDK supports push notifications based on Firebase Cloud Messaging.

In this section we will explain to you how to use Firebase Cloud Messaging (or FCM) with FollowAnalytics SDK.

Register your application

Copy the FCM Server key token (available through Firebase Console in your project settings).

and paste it to our platform in the application's administration.

Install Firebase Cloud Messaging

Download your Firebase Cloud Messaging config file in your Firebase console and add it into your cordova project at your root directory:

  |--- config.xml
  |--- followanalytics_configuration.json
  |--- google-services.json // <-
  |--- hooks/
  |--- node_modules/
  |--- package-lock.json
  |--- package.json
  |--- platforms/
  |--- plugins/
  |--- www/

That's it, FollowAnalytics SDK will now manage to install it into your application.

Verify your Google Services configuration

Be sure to check the configuration of Google Services as they have to be the following if you want FollowAnalytics SDK and Firebase to work.

  • The JSON for Google Services has the correct bundle id.
  • google-services.json file is in the root directory of your cordova project.

Call the register for push method (iOS only)


While on Android, the devices are registered for push notifications automatically after Firebase is integrated, this is not the case for iOS devices. You must first call a method that will let your device authorize the notifications

Add a call to registerForPush, either from your HTML code whenever you think the moment has come to ask the user for it. If, however your app code is already registered to send push notifications, then the you have nothing to do here and skip to the next section.


<a href="#" onclick="FollowAnalytics.registerForPush()">register for push</a>

Build in release mode for Android

The app must be built in release mode in order to receive push notifications


Events vs Attributes

The FollowAnalytics SDK allows you to tag both events and attributes. In this section, we explain how to utilize both of them in your app and benefit from analytics capabilities. If you are unsure about the difference, you may refer to the corresponding FAQ entry.

Data sent in debug mode will not appear on dashboards

When your app runs in DEBUG mode or in a simulator, the data is automatically sent as development logs, and is therefore not processed to be shown on the main UI page. DEBUG logs can be checked using the method given in the FAQ section.

App tags

The SDK allows you to log events happening in your code. These are the methods that you can call on the SDK:

// Log an event/error
<a href="#" onclick="FollowAnalytics.logEvent('My event')">Log an event</a>
<a href="#" onclick="FollowAnalytics.logError('My error')">Log an error</a>

You can also add details to the events and errors

// Log an event/error with details
<a href="#" onclick="FollowAnalytics.logEvent('My event', 'My event details')">Log an event</a>
<a href="#" onclick="FollowAnalytics.logError('My error', 'My error details')">Log an error</a>

Use the name as the unique identifier of your log. Use the details to be more specific and add some context. The details allow you to associate multiple key-values for additional context.

For logging geolocations, you can use the following methods:

// Log a location coordinates
<a href="#" onclick="FollowAnalytics.logLocationCoordinates(latitude, longitude)">Log Location</a>
<a href="#" onclick="FollowAnalytics.logLocationPosition(position)">Log Location</a> // Takes a Position object provided by the Geolocation API

The logLocationPosition(position) method can be used to pass to FollowAnalytics SDK a position object provided by the Geolocation API.

Events can be renamed on the FollowAnalytics platform

The name that you give to your event here can be overridden in the FollowAnalytics platform. For more information, reach out to your Customer Success Manager or message support.

Use the name as the unique identifier of your log. Use the details section to add specific details or context. The details field can either be a String or a Hash, so that you can associate multiple key-values for additional context.

For example, you can log the display of a view by writing the following:

FollowAnalytics.logEvent('Product view', Product reference);

FollowAnalytics.logEvent('Add product to cart', {'product_id': 'ABCD123','product_category': 'Jeans'});

Logging best practices

To ensure your tags are relevant and will end up empowering your team through FollowAnalytics, please read the Logging best practices entry in the FAQ section.

User ID and attributes

This section covers the integration of a user ID and customer attributes. The SDK allows you to set values for attributes FollowAnalytics has predefined as well as custom attributes which you can make yourself.

You don't need a user ID to set attributes

Attributes are tied to the device when no user ID is provided. If a user ID is set, a profile is created and can be shared across apps.

In both cases, attributes can be used in segments and campaigns to target users.

User ID

What is a user ID?

If users can sign in somewhere in your app, you can specify their identifier to the SDK. Unique to each user, this identifier can be an e-mail address, internal client identifier, phone number, or anything else that ties your customers to you. This is what we call the user ID.

A user ID enables you to relate any event to a specific user across several devices. It is also an essential component for transactional campaigns. A common user ID enables you connect to a CRM or other external systems.

To register the user identifier, use:


If you want to remove the user identifier (in case of a sign out for instance) use the following method:


Predefined attributes

The SDK allows to set values for both custom and predefined attributes.

For predefined attributes, the SDK has the following properties:

FollowAnalytics.UserAttributes.setCity("San Francisco");

They are "predefined" in the sense that they will be attached to default fields on your user profiles.

Custom attributes

Double check your custom attribute types

When a value for an unknown attribute is received by the server, the attribute is declared with the type of that first value.

If you change the type of an attribute in the SDK, values might be refused server-side. Please ensure the types match by visiting the profile data section of the product.

Set a custom attribute

To set your custom attributes, you can use methods that are adapted for each type:

FollowAnalytics.UserAttributes.setNumber('key', "1");
FollowAnalytics.UserAttributes.setString('key', "A custom string attribute");
FollowAnalytics.UserAttributes.setBoolean('key', "true");
FollowAnalytics.UserAttributes.setDate('key', "2016-10-26");
FollowAnalytics.UserAttributes.setDateTime('key', "2020-06-30T12:56:01.928+0100"); // Example using a string
FollowAnalytics.UserAttributes.setDateTime('key', new Date().toISOString()); // Example with a JavaScript Date object converted to an ISO String

For example, to set the user's job:

FollowAnalytics.setString("job", "Taxi driver");
Delete a custom attribute value

You can clear the value of an attribute using its key. For example, to delete the user's job:

Set of Attributes

You can add or remove an item to or from a set of attributes.

To add an item:

FollowAnalytics.addToSet("fruits", "apple");
FollowAnalytics.addToSet("fruits", "banana");

To remove an item:

FollowAnalytics.removeFromSet("fruits", "apple");

And to clear a set:


Opt-Out Analytics

What is Opt-out analytics?

The SDK can be configured to no longer track user information. This is what we call to opt out of analytics.

Once opted-out, no new data is collected, nor is it stored in the app. New session are not generated at launch and nothing is sent back to the server. This data includes the following:

  • tagged elements such as events, errors
  • new user identification and attributes
  • crash reports

When a user is opted-out of analytics, campaigns will continue to work with the following limitations:

  • No Contextual campaigns - as they depend on log tracking
  • No Transactional campaigns - as they depend on the user ID
  • No Dynamic campaigns - as they depend on users entering a segment
  • Campaigns filters will depend on old data (before the user opted-out)

All data collected before the user has opted-out is preserved within FollowAnalytics servers. This means that a user having opted-out will still receive campaigns based on data acquired before opting out (previous campaigns, existing segments, etc). The opt-in state is persisted between app starts (unless storage of the app is emptied).

To inspect and set the opt-out state, call the following methods:

FollowAnalytics.getOptInAnalytics(function(error, result) {
    if (!error) {
        // do something with the result
        // console.log(result);
    } else {
        // do something with the error
        // console.log(error);
    FollowAnalytics.setOptInAnalytics(true); // accepts true/false as input


You can record when the user expresses his demand to access or delete his personal data by calling one of the following methods:


The SDK will record all requests and send them to FollowAnalytics servers as soon as network conditions allow it. The SDK remembers pending requests between app restarts.


Campaign basics

What we mean by campaigns are the messages that you with to send to your user from the FollowAnalytics platform. Currently, FollowAnalytics enables you to send two types of campaigns: push notifications and in-app messages. Push notifications allow you to send messages to your user's home screen, whereas an in-app a message that is displayed in the app while the user is actively using it.

Before you start, be sure that the SDK is properly initialized. This includes registration for push notifications, which is covered in the integration section.

Rich push notifications (iOS Specific)

Rich push notifications on iOS

Rich push notifications are notifications with embedded rich media (images, GIFs, videos). They are only available on iOS 10 and above. Should a user have a version under iOS 10, they will receive rich push notifications but not be able to see the rich media included.

Notification Service Extension Framework


To make your app able to receive rich notifications & badge incrementation, follow these steps:

  1. In your Xcode project, add a new target.

  2. Select Notification Service Extension, give it a name and confirm. Then when prompted, activate the scheme.

Add the FANotificationExtension framework
  1. In your project settings, select your target and select the Build Phases tab:

    1. Press the + button, and select New Copy File Phase.

    2. On the newly added Copy File phase, change Destination to Frameworks.

    3. Press the + button.

    4. In the Choose item to add dialog, select the FANotificationExtension.framework inside the Frameworks folder.
    5. Click on Open button.
    6. Uncheck Copy items if needed box.
    7. Click on Finish button.
    8. In the Framework Search Paths fields of the Build Settings tab, add the path to the FANotificationExtension.framework.

    Make sure if your Framework Search Paths are equal to the Framework Search Paths of your main target.

Create an app group between your app and the extension

Before all, an App Group must be created.

Configuring the SDK to work with the extension

First, make sure you have set the proper App Group for the app target:

The appGroup parameter should be specified in the followanalytics_configuration.json file:

      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : true,
      "maxBackgroundTimeWithinSession" : 120,
      "apiKey" : "YOUR_API_KEY",
      "isVerbose" : false,
      "maxBackgroundTimeWithinSession" : 120,


Don't forget to run cordova prepare ios after add any configuration on followanalytics_configuration.json

Implement the Notification Service Extension

First, make sure you have set the proper App Group for the extension target:

Copy and paste the following implementation in the NotificationService file of the extension target you created and change the the name of the appGroup with the one you defined:

#import “NotificationService.h”
#import <FANotificationExtension/FANotificationExtension.h>

@interface NotificationService ()

@property(nonatomic, strong) void (^contentHandler)(UNNotificationContent* contentToDeliver);
@property(nonatomic, strong) UNMutableNotificationContent* bestAttemptContent;


@implementation NotificationService

- (void)didReceiveNotificationRequest:(UNNotificationRequest*)request
   withContentHandler:(void (^)(UNNotificationContent* _Nonnull))contentHandler {
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
                            completion:^(UNMutableNotificationContent* _Nullable newContent) {
                            NSLog(@"NotificationService: %@", request);
                            // Modify the notification content here...


- (void)serviceExtensionTimeWillExpire {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content,
    //otherwise the original push payload will be used.
import UserNotifications
import FANotificationExtension

class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest,
                                withContentHandler contentHandler:
                                @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

        if let bestAttemptContent = bestAttemptContent,
        let contentHandler = self.contentHandler {
        // Modify the notification content here...

            FANotificationService.getFAContentIfNeeded(with: request,
                                                        bestContent: bestAttemptContent,
                                                        appGroup: "group.your.identifier") {
                                                        (newContent) in
                                                        if let newC = newContent {

    override func serviceExtensionTimeWillExpire() {
        if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {

Badge Management


For using this feature, there are 3 prerequisites:

Badges are the numbers displayed on the icon of the app, indicating to user that the app has new information. The FollowAnalytics SDK handles the badge number automatically, but if you need to update it and you want to take in consideration the current value number from our SDK you can use the FABadge class which lets you set and get the SDK badge value thought the following methods:

[FABadge setBadge:INTEGER]; // Set the value of the icon badge number
[FABadge updateBadgeBy:INTEGER]; // Update the value of the icon badge number
[FABadge badge]; // Get the value of the icon badge number
FABadge.setBadge(Int) // Set the value of the icon badge number
FABadge.updateBadgeBy(Int) // Update the value of the icon badge number
FABadge.badge // Get the value of the icon badge number

Custom handling of rich campaigns

Rich campaigns can be handled directly by the application code, instead of being showed automatically by the SDK. The behavior is defined when creating the campaign, using the "automatically display content" switch.


For campaigns where the content is not handled by FollowAnalytics, implement the following FAFollowAppsDelegate method in your AppDelegate:

- (void)followAppsShouldHandleWebViewUrl:(NSURL *)url withTitle:(NSString *)webviewTitle;

For campaigns where the content is not handled by FollowAnalytics, you will need to extend com.followapps.android.CustomRichCampaignBaseReceiver and declare it in your AndroidManifest.xml. You'll need to use an intent-filter on BROADCAST_RICH_CAMPAIGNS_ACTION. For instance:

<receiver android:name=".RichCampaignDataReceiver" >

Where %YOUR_APP_PACKAGE_NAME% is your application package name.

The method onRichCampaignDataReceived must be overridden. Rich campaign parameters are provided as method arguments:

Customize the Icon Notification (Android specific)

For applications that targets at least Lollipop version, the push notification icon at the status bar needs to be updated according to this section and this section (tutorial for creating icons with android studio).

Make sure to rename all the icon images to ic_fa_notification.png for each density created.

Then, place them to your project under platforms/android/res folder and make sure that all your notifications looks right with the new color scheme. For example : yourproject/platforms/android/res/drawable-mdpi/ic_fa_notification.png

Icon colors

Update or remove assets that involve color. The system ignores all non-alpha channels in action icons and in the main notification icon. You should assume that these icons will be alpha-only. The system draws notification icons in white and action icons in dark gray.

Deep-linking: URL, Parameters

Campaigns created through FollowAnalytics allow to deep link to content in your app. You can either use an App Link, or use key-value parameters that are forwarded to your code.

Version 4.1.0 of the SDK introduced the possibility to use direct App Links like twitter://messages, which will send you to the corresponding screen inside the Twitter application.

To use App Links you need to enable Deep Linking switch in our UI, when creating a campaign. Use the App Link field to set the type of URLs schemas.

It can either be an URL Schema to an external application or for your own application.

Deep-linking parameters (Android Only)

On the platform, you can specify deep-linking parameters for your Push campaign. These parameters are passed to the app by the SDK. It is then up to the developer to implement the deep-linking in the app (specific path of screens, format of the arguments, etc.).

To handle the deeplinking from your javascript code, set a callback for the onPushMessageClicked event as soon as the device is ready:

onDeviceReady: function() {
    FollowAnalytics.on("onPushMessageClicked", function(data){

App Link

If an App Link is set on the Push campaign, it is passed to the callback, through the data argument, as an extra key-value pair. You can retrieve it from the key url as following : appLink = data.url

Pausing in-app campaigns

What is pausing and resuming an in-app campaign?

Pausing campaigns are used to prevent in-app from being displayed on certain screens and views of your app. You may pause a screen of the app when it is too important, or is part of a process that is too important to be interrupted by an in-app (i.e a payment screen in the process of the user making a purchase).

When the screen is safe to display an in-app, you resume in-app campaigns. Any campaign supposed to be displayed when the mechanism is paused, is stacked and shown as soon as the mechanism is resumed. This way you can send send in-app campaigns without impacting the user experience.

To pause and resume campaigns, add the following methods in you code at the location you wish the pause and resume to take effect:


Create safe spaces for you in-app messages

Rather than pause everywhere you have an important screen or process, you can pause right at the initialization of the SDK and resume in the areas you think it is safe for in-app campaigns to be displayed.

Archiving messages

FollowAnalytics SDK allows you to store campaigns's messages received by your app. This makes them available for custom usage, like building an inbox feature. All campaigns displayed by a device can be archived locally and accessed from the developer's code. In order to configure your campaign storage, you have to set the following FollowAnalyticsConfiguration properties on the followanalytics_configuration.json:

    "archiveInAppMessages": true,
    "archivePushMessages": true

Get all campaigns

FollowAnalytics.InApp.getAll(function(error, result) {
    if (!error) {
        // do something with the result
        // console.log(JSON.stringify(result));
    } else {
        // do something with the error
        // console.log(error);
FollowAnalytics.Push.getAll(function(error, result) {
    if (!error) {
        // do something with the result
        // console.log(JSON.stringify(result));
    } else {
        // do something with the error
        // console.log(error);

Get campaign by identifier

FollowAnalytics.InApp.get(identifier, function(error, result) {
    if (!error) {
        // do something with the result
        // console.log(JSON.stringify(result));
    } else {
        // do something with the error
        // console.log(error);
FollowAnalytics.Push.get(identifier, function(error, result) {
    if (!error) {
        // do something with the result
        // console.log(JSON.stringify(result));
    } else {
        // do something with the error
        // console.log(error);

Mark campaigns as read

FollowAnalytics.InApp.markAsRead([identifier1, identifier2, ...]);
FollowAnalytics.Push.markAsRead([identifier1, identifier2, ...]);

Mark campaigns as unread

FollowAnalytics.InApp.markAsUnread([identifier1, identifier2, ...]);
FollowAnalytics.Push.markAsUnread([identifier1, identifier2, ...]);

Delete campaigns

FollowAnalytics.InApp.delete([identifier1, identifier2, ...]);
FollowAnalytics.Push.delete([identifier1, identifier2, ...]);

Opening an external webview

The plugin allows you to launch a native web view with a given url and be able to performs logs from that external resource. In order to do so, if you want to open url https://s3-eu-west-1.amazonaws.com/fa-sdk-files/index.html in a native web view launched from your html code, call the following method from your PhoneGap HTML:

FollowAnalytics.openWebView(URL, TITLE, CLOSE_BUTTON_TEXT);

Something like:

<a href="#" onclick="FollowAnalytics.openWebView('https://s3-eu-west-1.amazonaws.com/fa-sdk-files/index.html', 'Test Log', 'Close'); return false;">Open WebView with title</a>

The URL argument will contain the url of the page to display (required), the TITLE argument will be shown as the title for the NavigationBar (optional), and the CLOSE_BUTTON_TEXT will contain the text for the close button (optional, defaults to “close”).

Please check the html at https://s3-eu-west-1.amazonaws.com/fa-sdk-files/index.html to see how to tag your external pages.

Current available methods are:

NOTE: if you're tagging from a link and the link has a real href set, the SDK will handle that for you, performing the onclick action and redirecting you right after.

Migration and Troubleshooting

Updating from 6.3.0 to 6.3.1

Updating from 6.2 to 6.3

Migration from 4.x

Although previous versions of the FollowAnalytics plugin respected Cordova guidelines of integration they still required developers to perform modifications to the native code for each supported platform.

This new version changes things as it can be used without having to modify nothing but the config.xml and the html/js code. If you plan to update from older versions, the shortest path would be to:

If you plan to keep the current code you'll need to remove all the code needed to integrate previous plugin versions (please check older plugin documentation to know exactly what to remove).


Inline JavaScript not executed

If you eventually run into an error like:

Refused to execute inline event handler because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.

Be sure to replace the line

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">

on your index.html by

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'" >

This will enable the logging of events.

Cannot find module 'xcode'

Execute the following command : npm install --save xcode and reinstall FollowAnalytics SDK plugin.

Cannot find module 'q'

Execute the following command : npm install --save q and reinstall FollowAnalytics SDK plugin.
