Basic Integration

Manual Installation

Please use the steps listed below under the section 'Android Studio.'

Maven

If you use Maven, add implementation com.tenjin:android-sdk:VERSION to your Gradle dependencies and add mavenCentral() to the source repositories if it’s not there already.

Android Studio

1. Download the latest Android SDK from here.

2. Add the Tenjin SDK into your Android Studio project. Go to the Project Navigator in Android Studio. Select the option Project in the Project Navigator. You will find the libs folder under the app module of your Android Studio project.

3. You need to add the file tenjin.jar or tenjin.aar to the libs folder.
   

4. In your Android Studio project under app module, select the build.gradle file, and add the following under the dependencies block:

   dependencies {
       implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
       implementation files('libs/tenjin.aar')
   }
   

   We have a demo project - tenjin-android-sdk-demo that demonstrates the integration of tenjin-android-sdk. You can this project as example to understand how to integrate the tenjin-android-sdk.

Google Play or Amazon store

If you distribute your apps on Google Play Store or Amazon store, implement the following initial setups.

Permission

The Tenjin SDK requires the following permissions:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- Required to get network connectivity (i.e. wifi vs. mobile) -->

Google Play Services requires all API level 32 (Android 13) apps using the advertising_id(Android Advertising ID (AAID)) to declare the Google Play Services AD_ID permission (shown below) in their manifest file. Please add this permission as soon as possible. You are also required to update the tenjin-android-sdk to version 1.12.8 in order to use the below permission.

<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

Android Advertising ID (AAID) and Install Referrer

Add Android Advertising ID (AAID) and Install Referrer libraries, add it to your build.gradle file.

dependencies {
  implementation 'com.google.android.gms:play-services-ads-identifier:{version}'
  implementation 'com.android.installreferrer:installreferrer:{version}'
}

To be able to collect Meta's Install Referrer, add these queries to your Android Manifest:

<queries>
  <package android:name="com.facebook.katana" />
</queries>

<queries>
  <package android:name="com.instagram.android" />
</queries>

If you haven't set up Facebook's SDK (Meta) yet, add the following to your AndroidManifest.xml file:

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id" />

Next, add this value to your strings.xml file:

<string name="facebook_app_id" translatable="false">YOUR_APP_ID</string>

App Store

By default, unspecified is the default App Store. Update the app store value to either googleplay or amazon, depending on your app.

1. AndroidManifest.xml:

<meta-data
    android:name="TENJIN_APP_STORE"
    android:value="googleplay" />

2. setAppStore():

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");

instance.setAppStore(TenjinSDK.AppStoreType.googleplay);

App Store Options

  TenjinSDK.AppStoreType.googleplay // Google Play App Store
  TenjinSDK.AppStoreType.amazon     // Amazon AppStore
  TenjinSDK.AppStoreType.other      // Other

App Initialization

1. Get your SDK_KEY from your app page. Note: SDK_KEY is unique for each of your app. You can create up to 3 keys for the same app.
   

2. In your Activity, import Tenjin: import com.tenjin.android.TenjinSDK;

3. In the onResume method of your main Activity class, add the following line of code:

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");

instance.connect();

NOTE: If your app has the logic to ask user's consent between onCreate and onResume, use onCreate instead of onResume for Tenjin SDK initialization because users who don't consent won't be tracked on onResume.

NOTE: Please ensure you implement this code on every onResume, not only on the first app open of the app. If we notice that you don't follow our recommendation, we can't give you proper support or your account might be suspended.

Other Android store

If you distribute your apps outside of Google Play Store or Amazon store(Other Android store), implement the following initial setups.

Permission

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- Required to get network connectivity (i.e. wifi vs. mobile) -->

Later this year, Google Play Services will require all API level 32 (Android 13) apps using the advertising_id(Android Advertising ID (AAID)) to declare the Google Play Services AD_ID permission (shown below) in their manifest file. Please add this permission as soon as possible. You are also required to update the tenjin-android-sdk to version 1.12.8 in order to use the below permission.

<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

Android Advertising ID (AAID) and Install Referrer

Add Android Advertising ID (AAID) and Install Referrer libraries, add it to your build.gradle file.

dependencies {
  implementation 'com.google.android.gms:play-services-ads-identifier:{version}'
  implementation 'com.android.installreferrer:installreferrer:{version}'
}

If you are using an Ad Network that targets the IMEI, you will need to add the following permissions enabled. (If you are distributing your apps in Google Play, please DO NOT add this permission.)

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

OAID

Tenjin supports promoting your app on other Android App Stores using the Android OAID. We have the following requirements for integrating OAID libraries.

MSA OAID

MSA OAID is an advertising ID for devices manufactured in China that the MSA (Mobile Security Alliance) provides. For integration with the MSA library, download the following oaid_sdk_1.0.25.aar and supplierconfig.json.

Add the following to your project gradle file:

implementation files('libs/oaid_sdk_1.0.25.aar')

Be sure to copy the supplierconfig.json file to the assets folder of your project.

Huawei OAID

For outside of China, you can collect OAID using the library provided by Huawei. For integration with the Huawei OAID library, add the following to your project:

In your build.gradle file, add the Maven address for the Huawei SDKs:

allprojects {
    repositories {
        google()
        maven { url 'https://developer.huawei.com/repo/' }
    }
}

dependencies {
    implementation 'com.huawei.hms:ads-identifier:{version}'
}

Huawei Install Referrer

If you are marketing your app with Huawei App Gallery, add both the Huawei OAID SDK from above and the Install Referrer library.

dependencies {

    implementation 'com.huawei.hms:ads-identifier:{version}'
    implementation 'com.huawei.hms:ads-installreferrer:{version}'

}

App Store

By default, unspecified is the default App Store. Update the app store value to other.

1. AndroidManifest.xml:

<meta-data
    android:name="TENJIN_APP_STORE"
    android:value="other" />

2. setAppStore():

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");

instance.setAppStore(TenjinSDK.AppStoreType.other);

App Initialization

1. Get your SDK_KEY from your app page. Note: SDK_KEY is unique for each of your app. You can create up to 3 keys for the same app.
   

2. In your Activity, import Tenjin: import com.tenjin.android.TenjinSDK;

3. In the onCreate method of your main Activity class, add the following line of code:

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");

instance.connect();

NOTE: Please ensure you implement this code on every onCreate, not only on the first app open of the app. If we notice that you don't follow our recommendation, we can't give you proper support or your account might be suspended.

Additional Integration

GDPR

The General Data Protection Regulation (EU) (GDPR) is a regulation in EU law on data protection and privacy in the European Union (EU) and the European Economic Area (EEA).

You need to get user consent whether they allow tracking or not in first ap open, then write the result into checkOptInValue() . After that, you can follow the inetgration as below. If you do not need to be GDPR compliant in your App, please just ignore this whole section.

As part of GDPR compliance, with Tenjin's SDK you can opt-in, opt-out devices/users, or select which specific device-related params to opt-in or opt-out. optOut() will not send any API requests to Tenjin, and we will not process any events.

To opt-in/opt-out:

import com.tenjin.android.TenjinSDK;

public class TenjinDemo extends ActionBarActivity {
    @Override
    public void onResume() {
        //standard code
        super.onResume()

        //Integrate TenjinSDK connect call
        String apiKey = "<SDK_KEY>";
        TenjinSDK instance = TenjinSDK.getInstance(this, apiKey);

        boolean userOptIn = checkOptInValue();

        if (userOptIn) {
            instance.optIn();
        }
        else {
            instance.optOut();
        }

        instance.connect();

        //Your other code...
        //...

    }

    protected boolean checkOptInValue(){
        // check opt-in value
        // return true; // if user opted-in
        return false;
    }
}

To opt-in/opt-out specific device-related parameters, you can use optInParams() or optOutParams().

• optInParams() will only send device-related parameters that are specified. optOutParams() will send all device-related parameters except ones that are specified.

• Kindly note that we require the following parameter to properly track devices in Tenjin's system. If the mandatory parameter is missing, the event will not be processed or recorded.

  • advertising_id

• If you are targeting IMEI and/or OAID Ad Networks, these params are required:

  • imei
  • oaid

• If you intend to use Google AdWords, these params are required:

  • platform
  • os_version
  • app_version
  • locale
  • device_model
  • build_id

If you want to only get specific device-related parameters, use optInParams(). In example below, we will only these device-related parameters: ip_address, advertising_id, limit_ad_tracking, and referrer.

String apiKey = "<SDK_KEY>";
TenjinSDK instance = TenjinSDK.getInstance(this, apiKey);

String[] optInParams = {"ip_address", "advertising_id", "limit_ad_tracking", "referrer"};
instance.optInParams(optInParams);

instance.connect();

If you want to send ALL parameters except specific device-related parameters, use optOutParams(). In the example below, we will send ALL device-related parameters except:

String apiKey = "<SDK_KEY>";
TenjinSDK instance = TenjinSDK.getInstance(this, apiKey);

String[] optOutParams = {"locale", "timezone", "build_id"};
instance.optOutParams(optOutParams);

instance.connect();

Opt in/out using CMP

You can automatically opt in or opt out using your CMP consents (purpose 1) which are already saved in the user's device. The method returns a boolean to let you know if it's opted in or out.

optInOutUsingCMP()

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");
optInOut = instance.optInOutUsingCMP(); 

Device-Related Parameters

Purchase Events

To understand user revenue and purchase behavior, developers can send transaction events to Tenjin. Tenjin will validate transaction receipts for you. Kindly note that we currently only support IAP transactions from Google Play.

IMPORTANT: You will need to add your app's public key in the Tenjin dashboard (under the app 'edit' page). You can retrieve your Base64-encoded RSA public key from the Google Play Developer Console > Select your app > Monetize > Monetization setup > Google Play Billing > Licensing: Base64-encoded RSA public key. Please note that for Android, we currently only support IAP transactions from Google Play.

After entering your Public Key into the Tenjin dashboard for your app, you can use the Tenjin SDK method below:

public void transaction(String productId, String currencyCode, int quantity, double unitPrice, String purchaseData, String dataSignature)

Example:

public void sendPurchaseEvent(Purchase purchase, Double price, String currencyCode) {
    String sku = purchase.getSku();
    String purchaseData = purchase.getOriginalJson();
    String dataSignature = purchase.getSignature();

    TenjinSDK instance = getTenjinInstance();
    instance.transaction(sku, currencyCode, 1, price, purchaseData, dataSignature);
}

You can verify if the IAP validation is working through our Live Test Device Data Tool. You should see a live event come in:

Disclaimer: If you are implementing purchase events on Tenjin for the first time, make sure to verify the data with other tools you’re using before you start scaling up your user acquisition campaigns using purchase data.

Amazon AppStore

Amazon AppStore receipt validation requires receiptId and userId parameters.

IMPORTANT: You will need to add your Amazon app's Shared Key in the Tenjin dashboard. The shared secret can be found on the Shared Key in your developer account with the Amazon Appstore account

Custom Events

NOTE: The initialization event connect() must come before sending any custom events.

You can use the Tenjin SDK to pass a custom event: eventWithName(String name).

The custom interactions with your app can be tied to level cost from each acquisition source that you use through Tenjin's service. Here is an example of usage:

String apiKey = <SDK_KEY>;
TenjinSDK instance = TenjinSDK.getInstance(this, apiKey);

//Integrate a custom event with a distinct name - ie. swiping right on the screen
instance.eventWithName("swipe_right");

Custom Events with values

You can use the Tenjin SDK to pass a custom event with an integer value: eventWithNameAndValue(String name, int value).

Passing an integer value with an event's name allows marketers to sum up and track averages of the values passed for that metric in the Tenjin dashboard. If you plan to use DataVault, these values can be used to derive additional metrics that can be useful.

String apiKey = <SDK_KEY>;
TenjinSDK.instance = TenjinSDK.getInstance(this, apiKey);

//Integrate a custom event with a distinct name and value - ie. paying 100 virtual coins for an item
instance.eventWithNameAndValue("item", 100);

Using the example above, the Tenjin dashboard will sum and average the values for all events with the name item.

Keep in mind that this event will not work if the value passed not an integer.

//Integrate a custom event with a distinct name and value - ie. paying 100 virtual coins for an item
instance.eventWithNameAndValue("item", "1");

Server-to-server integration

Tenjin offers server-to-server integration. This allows you to send your install and post-install events directly from your servers to Tenjin servers without needing an SDK integration. If you want to access to the documentation, please send email to support@tenjin.com.

App Subversion parameter for A/B Testing (requires DataVault)

If you are running A/B tests and want to report the differences, we can append a numeric value to your app version using the appendAppSubversion() method. For example, if your app version 1.0.1, and set appendAppSubversion(8888), it will report app version as 1.0.1.8888.

This data will appear within DataVault, where you will be able to run reports using the app subversion values.

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");
instance.appendAppSubversion(8888);
instance.connect();

LiveOps Campaigns

Tenjin supports retrieving of user attribution information, like sourcing ad network and campaign, from the SDK. This will allow developers to collect and analyze user-level attribution data in real-time. Here are the possible use cases using Tenjin LiveOps Campaigns:

• If you have your own data anlytics tool, custom callback will allow you to tie the attribution data to your in-game data per device level.
• Show different app content depending on where the user comes from. For example, if user A is attributed to organic and user B is attributed to Facebook and user B is likely to be more engaged with your app, then you want to show a special in-game offer after the user installs the app. If you want to discuss more specific use cases, please write to support@tenjin.com.

Customer User ID

You can set and get customer user id to send as a parameter on events.

.setCustomerUserId(userId: "user_id")

.getCustomerUserId()

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");
instance.setCustomerUserId(userId: "user_id");
userId = instance.getCustomerUserId(); 

Analytics Installation ID

You can get the analytics id which is generated randomly and saved in the local storage of the device.
getAnalyticsInstallationId()

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");
analyticsId = instance.getAnalyticsInstallationId; 

Retry Cache

You can enable/disable retrying and caching events and IAP when requests fail or users don't have internet connection. These events will be sent after a new event has been added to the queue and user has recovered connection.

.setCacheEventSetting(setting: true)

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");
instance.setCacheEventSetting(setting: true);

Impression Level Ad Revenue Integration

Tenjin supports the ability to integrate with the Impression Level Ad Revenue (ILRD) feature from,

• AppLovin
• Unity LevelPlay
• HyperBid
• AdMob
• TopOn
• CAS
• TradPlus

This feature allows you to receive events which correspond to your ad revenue is affected by each advertisement show to a user. To enable this feature, follow the below instructions.

Google DMA Parameters

If you already have a CMP integrated, Google DMA parameters will be automatically collected by the Tenjin SDK. There’s nothing to implement in the Tenjin SDK if you have a CMP integrated. If you want to override your CMP, or simply want to build your own consent mechanisms, you can use the following:

setGoogleDMAParameters(boolean, boolean)

TenjinSDK instance = TenjinSDK.getInstance(this, "<SDK_KEY>");
instance.setGoogleDMAParameters(adPersonalization, adUserData); 

To explicitly manage the collection of Google DMA parameters, you have the flexibility to opt in or opt out at any time. While the default setting is to opt in, you can easily adjust your preferences using the optInGoogleDMA or optOutGoogleDMA methods, ensuring full control over your data privacy settings:

instance.optInGoogleDMA(); 
instance.optOutGoogleDMA(); 

Testing

You can verify if the integration is working through our Live Test Device Data Tool. Add your advertising_id or IDFA/GAID to the list of test devices. You can find this under Support -> Test Devices. Go to the SDK Live page and send the test events from your app. You should see live events come in:
