GoogleAnalyticsBridge

Google Analytics Bridge is built to provide an easy interface to the native Google Analytics libraries on both iOS and Android.

Important: This library requires React Native v0.19+.

Why a native bridge? Why not use just JavaScript?

The key difference with the native bridge is that you get a lot of the metadata handled automatically by the Google Analytics native library. This will include the device UUID, device model, viewport size, OS version etc.

You will only have to send in a few parameteres when tracking, e.g:

import GoogleAnalytics from 'react-native-google-analytics-bridge';
GoogleAnalytics.setTrackerId('UA-12345-1');

GoogleAnalytics.trackScreenView('Home');
GoogleAnalytics.trackEvent('testcategory', 'testaction');

Installation with rnpm

1. npm install --save react-native-google-analytics-bridge
2. rnpm link react-native-google-analytics-bridge

With this, rnpm will do most of the heavy lifting for linking, but for iOS you will still need to do step 5 from the manual installation guide below.

Manual installation iOS

1. npm install --save react-native-google-analytics-bridge
2. In XCode, right-click the Libraries folder under your project ➜ Add Files to <your project>.
3. Go to node_modules ➜ react-native-google-analytics-bridge ➜ ios ➜ RCTGoogleAnalyticsBridge and add the RCTGoogleAnalyticsBridge.xcodeproj file.
4. Add libRCTGoogleAnalyticsBridge.a from the linked project to your project properties ➜ "Build Phases" ➜ "Link Binary With Libraries"
5. Next you will have to link a few more SDK framework/libraries which are required by GA (if you do not already have them linked.) Under the same "Link Binary With Libraries", click the + and add the following:
6. CoreData.framework
7. SystemConfiguration.framework
8. libz.tbd
9. libsqlite3.0.tbd
10. Optional step: If you plan on using the advertising identifier (IDFA), then you need to do two things:
11. Add AdSupport.framework under "Link Binary With Libraries". (As with the other frameworks in step 5).
12. Go to Xcode ➜ Libraries ➜ RCTGoogleAnalyticsBridge.xcodeproj ➜ right-click google-analytics-lib. Here you need to Add files to .., and add libAdIdAccess.a from the google-analytics-lib directory. This directory is located in the same node_modules path as in step 3.

Prerequisites for Android

Make sure you have the following SDK packages installed in the Android SDK Manager:

• Google Repository
• Google Play services
• Google APIs (Atom) system image

Consult this guide if you are unsure how to do this. Specifically step 3 for the mentioned packages.

Manual installation Android

1. npm install --save react-native-google-analytics-bridge
2. Add the following in android/setting.gradle

...
include ':react-native-google-analytics-bridge', ':app'
project(':react-native-google-analytics-bridge').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-google-analytics-bridge/android')

3. And the following in android/app/build.gradle

...
dependencies {
    ...
    compile project(':react-native-google-analytics-bridge')
}

4. Register package in MainActivity.java

// Step 1; import package:
import com.idehub.GoogleAnalyticsBridge.GoogleAnalyticsBridgePackage;

public class MainActivity extends ReactActivity {
  ...

    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            // Step 2; register package:
            new GoogleAnalyticsBridgePackage()
        );
    }
}

Android build problem

Some people have had problems being hit with Unknown source file : com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzmu; after installing this (or similar modules).

This might be because you are using another module which also uses play-services, but targets a different version of play-services. In the build.gradle-file of this module, we target com.google.android.gms:play-services-analytics:8.+. In other words, we try to use the latest (8.x.x) version of play-services.

If some other module is targetting a previous version, say 8.3.0, then adding the following to your (React Native-project) build.gradle may be helpful:

compile("com.google.android.gms:play-services-analytics:8.3.0"){
    force = true
}

That should force the app to compile the 8.3.0 version of the dependency my module uses. Obviously, this might not be a solution if several modules are depending on conflicting versions.

I would recommend other module authors which also depend on play-services to target 8.+ instead of a specific minor version.

Google Analytics Javascript API

setTrackerId(trackerId)

• trackerId (required): String, your tracker id, something like: UA-12345-1

Important: Call once on app startup to set the tracker id for all subsequent static calls.

import GoogleAnalytics from 'react-native-google-analytics-bridge';
GoogleAnalytics.setTrackerId('UA-12345-1')

trackScreenView(screenName)

• screenName (required): String, name of current screen

Important: Calling this will also set the "current view" for other calls. So events tracked will be tagged as having occured on the current view, Home in this example. This means it is important to track navigation, especially if events can fire on different views.

See the Google Analytics docs for more info

GoogleAnalytics.trackScreenView('Home')

trackEvent(category, action, optionalValues)

• category (required): String, category of event
• action (required): String, name of action

// or
GoogleAnalytics.trackEvent('testcategory', 'testaction', {label: 'v1.0.3', value: 22});

trackTiming(category, value, optionalValues)

• category (required): String, category of the timed event

setUser(userId)

• userId (required): String, an anonymous identifier that complies with Google Analytic's user ID policy

See the Google Analytics for more info.

GoogleAnalytics.setUser('12345678');

allowIDFA(enabled)

• enabled (required): Boolean, true to allow IDFA collection, defaults to true.

Also called advertising identifier collection, and is used for advertising features.

Important: For iOS you can only use this method if you have done the optional step 6 from the installation guide. Only enable this (and link the appropriate libraries) if you plan to use advertising features in your app, or else your app may get rejected from the AppStore.

See the Google Analytics for more info.

GoogleAnalytics.allowIDFA(true);

setDryRun(enabled)

• enabled (required): Boolean, indicating if the dryRun flag should be enabled or not.

When enabled the native library prevents any data from being sent to Google Analytics. This allows you to test or debug the implementation, without your test data appearing in your Google Analytics reports.

GoogleAnalytics.setDryRun(true);

setDispatchInterval(intervalInSeconds)

• intervalInSeconds (required): Number, indicating how often dispatches should be sent

Events, screen views, etc, are sent in batches to your tracker. This function allows you to configure how often (in seconds) the batches are sent to your tracker. Recommended to keep this around 20-120 seconds to preserve battery and network traffic. This is set to 20 seconds by default.

GoogleAnalytics.setDispatchInterval(30);

setTrackUncaughtExceptions(enabled)

• enabled (required): Boolean

Sets if uncaught exceptions should be tracked. This is enabled by default.

GoogleAnalytics.setTrackUncaughtExceptions(true);

setAnonymizeIp(enabled)

Sets if AnonymizeIp is enabled. This is disabled by default. If enabled the last octet of the IP address will be removed.

GoogleAnalytics.setAnonymizeIp(true);

setOptOut(enabled)

• enabled (required): Boolean

Sets if OptOut is active and disables Google Analytics. This is disabled by default. Note: This has to be set each time the App starts.

GoogleAnalytics.setOptOut(true);

Google Tag Manager Javascript API

The GoogleTagManager type is available at GoogleAnalytics.GoogleTagManager. If you want to use it alongside GoogleAnalytics:

import GoogleAnalytics, { GoogleTagManager } from 'react-native-google-analytics-bridge';
GoogleTagManager.openContainerWithId('GT-NZT48')
.then(() => GoogleTagManager.stringForKey('pack'))
.then((str) => console.log('Pack: ', str));

All methods returns a Promise.

openContainerWithId(containerId)

• containerId (required): String, your container id.

Important: Call once to open the container for all subsequent static calls.

GoogleTagManager.openContainerWithId('GT-NZT48')
.then((..) => ..)

stringForKey(key)

Parameter(s)

• key (required): String

Returns:

• value: String

Retrieves a string with the given key from the opened container.

GoogleTagManager.stringForKey('key').then((val) => console.log(val));

boolForKey(key)

Parameter(s)

• key (required): String

Returns:

• value: Boolean

Retrieves a boolean value with the given key from the opened container.

GoogleTagManager.boolForKey('key').then((val) => console.log(val));

doubleForKey(key)

Parameter(s)

• key (required): String

Returns:

• value: Number

Retrieves a number with the given key from the opened container.

GoogleTagManager.doubleForKey('key').then((val) => console.log(val));

Simple A/B-testing

Setting up A/B-testing requires setup of containers in Google Tag Manager, and connecting this with Goals/Experiments in Google Analytics.

This blog post details how to do this. This guide from Google will also prove helpful (and is referenced in the aforementioned blog post).

Then you can use our Google Tag Manager implementation to pull values out of the container, and track events in Google Analytics in order to complete "goals".

In this way, the different containers (A/B) the user is given, will be linked to whether or not they accomplish the given goal.

Google Analytics Logging

There is a divergence in how the iOS and Android versions of the native library handles logging.

For Android you can check the GA logs with your favorite terminal by using adb logcat.

For iOS there is a logger in the internal library that writes events to the XCode output window. In order to control the logLevel you can add an item in your Info.plist with the key GAILogLevel. The value you use is a number which corresponds to your desired log-level:

• 0: None
• 1: Errors
• 2: Warnings
• 3: Info
• 4: Verbose
