Android

SDK is available as a library in AAR (recommended) and JAR. The library is available in JCenter and on GitHub repository.

Step 1. If you use Gradle for the applications build, specify the following relationship in build.gradle files in dependancy block:

dependencies {
    implementation 'com.devtodev:android:1.13.9'
    implementation 'com.google.android.gms:play-services-base:15.0.1'
}

In case you don't use Gradle, download it and add the library into the project.

Step 2. Initialize the library in the first Activity method onCreate() in the following way:

public class MyActivity extends Activity {
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          // Initialization devtodev SDK
          DevToDev.init(this, APP_ID, SECRET_KEY);
      }
}

App ID and Secret key can be found in the application settings (Open "My apps" → App Name → "Settings" → "Integration").

Additional initialization

If the application you integrate SDK in is a part of cross-platform project, then the user data initialization is required.

Since the analytics of cross-platform projects is based on an unique user (unlike the usual projects where it is based on device identifiers), you have to:

• Set the unique cross-platform user identifier (it will be used for cross-platform project data collection).

• Actualize the user data. Mostly it is about game applications where the player has a game level as a characteristic. For such projects you need to set the current player level.

We recommend you to set the user identifier before SDK initialization, otherwise the user identifier from the previous session will be used since the SDK initialization moment till the setUserID method call.

If your cross-platform application supposes to be used without cross-platform authorization, don't use the setUserID method or use the empty string ("") as the user identifier. SDK will assign the unique identifier to user. This identifier will we used until the real cross-platform identifier assigns to the user.

/**
* Method allows to initialize the user. It applies when SDK initialization or user relogin.
* @param String activeUserId - unique cross-platform user identifier (max. 64 symbols)
*/
DevToDev.setUserId(activeUserId);

/**
* Method sets the current user level. Using this method allows to actualize the SDK user data
* in game cross-platform applications.
* @param int level - number of current game level of the user
*/
DevToDev.setCurrentLevel(currentLevel);

/**
* devtodev SDK initialization
* @param String appId - devtodev App Id
* @param String secretKey - Secret key
* devtodev App Id and Secret key can be found in the devtodev application
* settings page ("My apps" → App Name → "Settings" → "Integration")
*/
DevToDev.init(getBaseContext(), appId, secretKey);

Attention! If your application allows user to relogin (changing the user during the working session of application), then the setUserID andsetCurrentLevel methods should be called just after the authorization. You don't need to call the SDK initialization one more time.

Debug mode

To enable the debug mode and make SDK notifications displayed in the console use this method:

/**
* @param logLevel
*/
DevToDev.setLogLevel(LogLevel logLevel);
