Android

The SDK is available as an AAR (recommended) and JAR library. The library is available in the MavenCentral and GitHub repository.

Google implementation

Attention!

From the SDK version com.devtodev:android-analytics:'2.2.3' and above you need to add com.devtodev:android-google:'1.0.1'.

This framework encapsulates work with Google ads ID. When developing and publishing apps for kids COPPA, you don’t need com.devtodev:android-google. You can find more information about working with COPPA at the end of this guide.

Step 1. Declare repositories

In the Project build.gradle file, declare the mavenCentral repository:

repositories {
   //.. other repositories 
   mavenCentral()
}

Step 2. Add Gradle Build Dependencies

If you use Gradle for building apps specify the following dependencies in the application build.gradle file.

Kotlin

dependencies {
    // Requirement
    implementation ("com.google.code.gson:gson:*.*.*")
    implementation ("com.google.android.gms:play-services-ads-identifier:*.*.*")
    // Starting from version 2.2.3 and above, it is required
    implementation ("com.devtodev:android-google:*.*.*")

    // if you use AAR (recommended) or JAR downloaded from GitHub, please add:
    implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("*.aar"))))

    // or just add the dependency, get the latest version from
    // https://mvnrepository.com/artifact/com.devtodev/android-analytics
    implementation ("com.devtodev:android-analytics:*.*.*")

    // Optional (recommended)
    implementation ("com.android.installreferrer:installreferrer:*.*.*")
}

Peculiarities of working with dependencies

Working with Advertising ID with Android API level less than 26

If you plan to use com.google.android.gms:play-services-ads-identifier:18.2.0 and above, you need to add com.android.tools:desugar_jdk_libs to maintain backward compatibility with devices with API level less than 26, see Use Java 8 language features and APIs | Android Studio | Android Developers

Kotlin

android {
    defaultConfig {
        // Required when setting minSdkVersion to 20 or lower
        multiDexEnabled = true
    }
    compileOptions {
        // Flag to enable support for the new language APIs
        coreLibraryDesugaringEnabled = true
        // Sets Java compatibility to Java 8
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}
dependencies {
    // For AGP 7.4+
    coreLibraryDesugaring ("com.android.tools:desugar_jdk_libs:2.0.3")
    // For AGP 7.3
    // coreLibraryDesugaring ("com.android.tools:desugar_jdk_libs:1.2.3")
    // For AGP 4.0 to 7.2
    // coreLibraryDesugaring ("com.android.tools:desugar_jdk_libs:1.1.9")
}

Groovy

We also recommend AGP 8.0+ as it makes it easier to configure com.android.tools:desugar_jdk_libs

Huawei implementation

Step 1. Declare repositories

If you use Gradle for compiling apps, declare the following dependencies in the build.gradle file in the dependency block:

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

allprojects {
    repositories {
        //.. other repositories
        mavenCentral()
        // Configure the Maven repository address for the HMS Core SDK.
        maven {url 'https://developer.huawei.com/repo/'}
    }
}

Step 2. Add Gradle Build Dependencies

In the Project build.gradle file declare the agconnect plugin

dependencies {
    classpath 'com.huawei.agconnect:agcp:*.*.*'
}

In the application build.gradle file declare the following dependencies:

Kotlin

dependencies {
    // Requirement
    implementation ("com.google.code.gson:gson:*.*.*")
    implementation ("com.huawei.agconnect:agconnect-core:*.*.*")
    implementation ("com.huawei.hms:opendevice:*.*.*")
    // Starting from version 2.2.3 and above, it is required
    implementation ("com.devtodev.android-huawei:*.*.*")
    implementation ("com.huawei.hms:ads-identifier:*.*.*")
    
    // if you use AAR (recommended) or JAR downloaded from GitHub, please add:
    implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("*.aar"))))
    
    // or just add the dependency, get the latest version from
    // https://mvnrepository.com/artifact/com.devtodev/android-analytics
    implementation ("com.devtodev:android-analytics:*.*.*")
}

Groovy

And add a plugin:

plugins {
    //.. other plugins
    id 'com.huawei.agconnect'
}

For more information see huawei official documents.

Step 3. AppGallery

The com.devtodev.android-huawei framework works with OAID and ODID IDs. In case the OAID is undefined, we use the ODID. For both IDs to work correctly, take the following steps:

1. Create a project and an app in AppGallery. Open AppGalleryConnect → Project Settings.

2. Sign your app using a certificate (see here).

3. Enter SHA-256 certificate in the App information section. Read more about certificate creation here.

After taking all the steps described above, open the ‘App information’ section and download agconnect-services.json. You need to place this file in the app folder (read more).

If during testing the app you see that OAID is unavailable and OAID throws errors, you need to first of all check that the tested build is signed with a certificate.

SDK Initialization

Use the following way to initialize the library in the first Activity onCreate() method:

Kotlin

class MainActivity : Activity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
      
        val analyticsConfiguration = DTDAnalyticsConfiguration()
        analyticsConfiguration.logLevel = DTDLogLevel.Error
        DTDAnalytics.initialize("App ID", analyticsConfiguration, context = this)
    }
}

Java

You can find the App ID in the settings of the respective app in devtodev (Settings → SDK → Integration → Credentials).

For Cross-platform type projects use App ID + Platform ID .

• config - is a DTDAnalyticsConfiguration object instance that is used for specifying additional properties during initialization.

DTDAnalyticsConfiguration

Parameter	Type	Description
currentLevel	Integer	The player level at the moment of devtodev SDK initialization. It’s optional but we recommend using it for improving data accuracy.
userId	String	A custom user ID assigned by the developer. In the case of default calculation by device IDs, the identifier can be used for searching users in devtodev. In case the project uses calculation by user IDs, the parameter is mandatory because it becomes the principal calculation ID in devtodev.
trackingAvailability	DTDTrackingStatus (enum)	The property allows or disallows devtodev tracking of the user. By default, it is set to DTDTrackingStatus.enable. SDK stores the previously assigned value. Pass DTDTrackingStatus.disable if the user opted out of tracking in line with GDPR.
logLevel	DTDLogLevel (enum)	The level of logging the SDK activity. The DTDLogLevel.no value is used by default. For troubleshooting during integration it is recommended to set it to DTDLogLevel.debug, and either switch it off DTDLogLevel.no. Use DTDLogLevel.no in the release version.

Example:

Kotlin

val config = DTDAnalyticsConfiguration()
config.currentLevel = 1
config.userId = "CustomUserID"
config.trackingAvailability = DTDTrackingStatus.Enable
config.logLevel = DTDLogLevel.No
DTDAnalytics.initialize("App ID", config, context = this)

Java

SDK obfuscation rules

Add the following strings to the proguard-rules.pro file of your app

-keep class com.devtodev.** { *; }
-dontwarn com.devtodev.**
// For Google Mobile Services 
-keep class com.google.android.gms.** { *; }
// For Huawei Mobile Services 
-keep class com.huawei.hms.**{*;}

Apps targeted at children

When developing and publishing apps targeted at children under 13 years old, you need to ensure special conditions for data processing. Any mobile app aimed at children or intended for users in a region with strict regulations on child online protection, must comply with current laws.

Please study the following requirements:

• USA: Children’s Online Privacy Protection Act (COPPA)

• EU: General Data Protection Regulation (GDPR) Article 8

If your app has to comply with the legal requirements (COPPA), use the following recommendations:

1. Implement the coppaControlEnable method. The method disables collection of ad IDs and vendor IDs.

2. If your app is using Google services, remove the following dependencies from gradle:

   'com.google.android.gms:play-services-ads-identifier'  
   'com.devtodev:android-google'

3. If your app is using Huawei services, remove the following dependencies from gradle:

   'com.huawei.hms:ads-identifier' 
   'com.huawei.hms:opendevice' 
   'com.devtodev.android-huawei'

Call the coppaControlEnable method before SDK initialization. If the method was not called, the SDK will work as before.

Kotlin

DTDAnalytics.coppaControlEnable()
DTDAnalytics.initialize("App ID", config, context = this)
