Quick Start Guide

Before you can take advantage of our SDK, you need to install the module(s) you want to use, initialize the SDK, and understand the order of operations.

Prerequisites

Before you start, you’ll need two keys. See Authentication you don’t have them, or don’t know where to find them.

• Your sourceAn integration that feeds data into Customer.io—a source of data. API Key (sometimes referenced as a CDP_API_KEY).
• Your Site IDEquivalent to the user name you’ll use to interface with the Journeys Track API; also used with our JavaScript snippets. You can find your Site ID under Settings > Workspace Settings > API Credentials to initialize the MessagingInApp package.

1. Create an Android Source

Before you can integrate your app, you need to tell Customer.io that you have an Android app. This is what we call a sourceAn integration that feeds data into Customer.io—a source of data..

Your source provides the API key you’ll use to initialize the SDK.

1. Go to Data & Integrations > Integrations and click Add Integration.
2. Select Android.

   

   
3. Enter a Name for your integration, like “My Android App”.
4. We’ll present you with a code sample containing a cdpApiKey that you’ll use to initialize the SDK. Copy this key and keep it handy.
5. Click Complete Setup to finish setting up your integration.

   

   

Now the Integrations page shows that your Android integration is connected to your workspace. You can also connect your Android integration to other services if you want to send your mobile data to other places outside of Customer.io—like your analytics provider, data warehouse, or CRM.

2. Install and Initialize the SDK

Use the instructions below to install and initialize the SDK. We’ve based the code samples for these steps on sample apps in our Android SDK repository. Check out the samples directory to see complete working examples for both Kotlin and Java.

1. Before you add Customer.io dependencies, update your repositories in your build.gradle or settings.gradle file.

   android {
     repositories {
       google()
       mavenCentral()
     }
     ...
   }

2. Add Customer.io packages as dependencies in your build.gradle file.

   dependencies {
     implementation "io.customer.android:datapipelines:4.5.3"
     implementation "io.customer.android:messaging-push-fcm:4.5.3"
     implementation "io.customer.android:messaging-in-app:4.5.3"
   }

3. 3. Initialize the CustomerIOBuilder in your Application class, so you can access it from any part of your application using the instance() method. Within the builder, you can add and configure modules.

      If you’re in our EU region, make sure that you set Region.EU.

   4. (Optional) Add and configure the MessagingInApp module. You’ll need your Site ID. This tells the SDK which Customer.io workspace your messages come from.
   5. (Optional) Add the MessagingPushFCM module to send push notifications.

   class MainApplication : Application() {
   
       @Inject
       lateinit var preferences: PreferenceRepository
   
       override fun onCreate() {
           super.onCreate()
   
           // Step 3
           CustomerIOBuilder(
               applicationContext = this,
               cdpApiKey = "your_cdp_api_key"
           ).apply {
               // If you're in the EU, set Region.EU
               region(Region.US)
   
               // Step 4: optional, support in-app messages
               // Again, if you're in the EU, set Region.EU
               addCustomerIOModule(
                   ModuleMessagingInApp(
                       config = MessagingInAppModuleConfig.Builder(
                           siteId = "your_site_id",
                           region = Region.US
                       ).setEventListener(InAppMessageEventListener()).build()
                   )
               )
   
               // Step 5: optional, support push notifications
               addCustomerIOModule(ModuleMessagingPushFCM())
               build()
           }
       }
   }

6. Add a way to identify people. While we support anonymous events, most of Customer.io’s features rely on identified people.

   We’ve provided an example from our sample apps. You’ll find our sample apps in the SDK’s /samples directory. They can help you better understand how to implement our SDK.

     private fun login(
         email: String,
         name: String,
         isGuest: Boolean = false,
         onLoginSuccess: () -> Unit
     ) {
         viewModelScope.launch(Dispatchers.IO) {
             userRepository.login(email = email, name = name, isGuest = isGuest)
             CustomerIO.instance().identify(
                 userId = email,
                 traits = mapOf("name" to name, "is_guest" to isGuest)
             )
             CustomerIO.instance().track(
                 name = "login",
                 properties = mapOf("name" to name, "email" to email)
             )
             withContext(Dispatchers.Main) {
                 onLoginSuccess.invoke()
             }
         }
     }
