    timeUnitTimeUnittime unit. Must be greater or equal to MILLISECONDS

Decision Mode

DecisionApi Mode

When the SDK is running in DecisionApi mode, the campaign assignments and targeting validation take place server-side. In this mode, each call to the fetchFlags method to refresh the flags will create an HTTP request.

Bucketing Mode

When the SDK is running in Bucketing mode, the SDK downloads all the campaigns configurations at once in a single bucketing file so that variation assignment can be computed client-side by the SDK. This bucketing file is stored in cache and will only be downloaded again when campaign configurations are modified in the Flagship interface. Learn more

SDK Status

List of the possible SDK status :

StatusDescription
NOT_INITIALIZEDFlagship SDK has not been started or initialized successfully.
STARTINGFlagship SDK is starting.
POLLINGFlagship SDK has been started successfully but is still polling campaigns. (Only when Bucketing mode is used)
PANICFlagship SDK is ready but is running in Panic mode: All visitor's features are disabled except 'fetchFlags' which refreshes this status.
READYFlagship SDK is ready to use.

It is possible to get the current status via the method getStatus() from the Flagship class.

  • public Status getStatus()

    Return the current SDK status

Status status = Flagship.getStatus()

Create a new visitor

The visitor instance is a helper object that lets you manage the context and campaigns for a user identified by a unique ID.

The user context is a property dataset that defines the current user of your app. This dataset is sent and used by the Flagship Decision API as targeting criteria for campaign assignment.

For example, if you want to enable or disable a specific feature based on VIP status, you would pass this attribute as a key-value pair in the user context so that the Decision API can enable or disable the corresponding feature flag for the user.

Visitor visitor = Flagship.newVisitor("visitor_unique_id")
                .context(new HashMap<String, Object>() {{
                    put("age", 32);
                    put("isVip", true);
                }})
                .hasConsented(true)
                .isAuthenticated(true)
                .build();

Updating the visitor context

The user context is a property dataset that defines the current user of your app. This dataset is sent and used by the Flagship Decision API as targeting criteria for campaign assignment.

The following method from the Visitor instance allows you to set new context values matching the given keys.

Visitor visitor = Flagship.newVisitor("visitor_unique_id")
                .context(new HashMap<String, Object>() {{
                    put("age", 32);
                    put("isVip", true);
                }})
                .build();

visitor.updateContext("lastPurchaseDate", 1615384464);

public <T> void updateContext(String key, T value)

                  put("isVip", true);
              }})
              .build();
HashMap<String, Object visitorContext = visitor.getContext();

Managing visitor campaigns and their flags


Fetching Flags

The fetchFlags() method of the Visitor instance automatically updates the campaign assignments according to the current user context and retrieves applicable flags.

These flags are then stored in the SDK and updated asynchronously when fetchFlags() is called.


Visitor visitor = Flagship.newVisitor("visitor_unique_id").build();
visitor.updateContext("postcode", "31200");
visitor.fetchFlags().get(); // Synchronous Blocking call
visitor.fetchFlags().whenComplete((instance, error) -> { // Asynchronous non blocking call
    // flag synchronization has been completed.
});

public CompletableFuture<Visitor> fetchFlags()

This function will call the decision api and update all the campaigns flags from the server according to the visitor context.

ReturnDescription
CompletableFuture<Visitor>Return a CompletableFuture to manage sync/async call to the decision api.

Getting flags

Once the campaign has been assigned and fetched, all the flags are stored in the SDK. You can retrieve these flags using the following functions from the Visitor instance:

Visitor visitor = Flagship.newVisitor("visitor_unique_id").build();
visitor.updateContext("isVip", true);
visitor.fetchFlags().whenComplete((instance, error) -> {
    Flag<Boolean> displayVipFeature = visitor.getFlag("displayVipFeature", false);
});

public <T> Flag<T> getFlag(String key, T defaultValue)

Retrieve a Flag object by its key. If no flag match the given key an empty flag will be returned. Call exists() to check if the flag has been found.

ParameterTypeDescription
keyStringkey associated to the flag.
defaultValueTflag default fallback value.

🚧

  • Default value must be one of the following type : String, Boolean, Number, JSONArray, 'JSONObject'.

Getting flags current values

To retrieve flag current value, simply call value() method of the Flag object.

Visitor visitor = Flagship.newVisitor("visitor_1");
visitor.updateContext("isVip", true);
visitor.fetchFlags().whenComplete((instance, error) -> {
    Boolean displayVipFeature = visitor.getFlag("displayVipFeature", false).value(false);
    // display or hide the vip feature
});

fun value(userExposed: Boolean = true): T?

Returns the value from the assigned campaign variation or the Flag default value if the Flag does not exist, or if types are different.

Parameter

Type

Description

userExposed

Boolean

Tells Flagship the user have been exposed and have seen this flag. This will increment the visits for the current variation on your campaign reporting.
If needed it is possible to set this param to false and call userExposed() afterward when the user sees it.

Getting flags campaigns metadata

You may need to send campaign IDs or variation IDs to a third party for reporting and/or analytics purposes. It is possible to retrieve campaigns metadata for a specific Flag.

val visitor = Flagship.newVisitor("visitor_id").build();
visitor.updateContext("isVip", true);
visitor.fetchFlags().get();
FlagMetadata campaignMetadata = visitor.getFlag("displayVipFeature", false).metadata();

fun metadata() : FlagMetadata

Return the flag campaign information metadata or an empty object if the Flag doesn't exist or if the default value type does not correspond to the Flag type in Flagship.

FlagMetadata

Field

Type

Description

campaignId

String

Campaign identifier the flag belongs to.

variationGroupId

String

Variation group identifier the flag belongs to.

variationId

String

Variation identifier the flag belongs to.

isReference

Boolean

Is the flag from the original variation.

campaignType

String

Type of the flag campaign.

slug

String

Campaign custom id.

Report a Flag exposition

When the method value() of the Flag instance is called, You have the possibility to tell the SDK that the user have seen the effets of this Flag, unless you pass false to value(). In this case you will have to call userExposed() when necessary.

There are two options for exposing a user to a flag:

  1. Pass an userExposed=true parameter to the value() method.
  2. Use the following userExposed() method from the Flag instance.

Visitor visitor = Flagship.newVisitor("visitor_1").build();
visitor.updateContext("isVip", true);
visitor.fetchFlags().whenComplete((instance, error) -> {

val displayVipFeature = visitor.getFlag("displayVipFeature", false).value(true);
  
// or
 
val displayVipFeature = visitor.getFlag("displayVipFeature", false).value(false); 
// ...
visitor.userExposed();
    
}

fun userExposed()

Tells Flagship the user have been exposed and have seen this flag. This will increment the visits for the current variation on your campaign reporting. No user exposition will be sent if the Flag doesn't exist or if the default value type do not correspond to the Flag type in Flagship.

ParameterTypeDescription
keyStringkey associated to the Flag to report.

Check if a Flag exists

fun exists()

This method will return true if a Flag exists in Flagship

Visitor visitor = Flagship.newVisitor("visitor_1").build();
visitor.updateContext("isVip", true);
visitor.fetchFlags().whenComplete((instance, error) -> {

  val isDisplayVipFeatureExists = visitor.getFlag("do_not_exists", false).exists();

}

Managing visitor consent

The Visitor class provides a method to let you manage visitor consent for data privacy usage. When False, campaign activation and hits will be disabled and cache cleared.

public void setConsent(Boolean hasConsented)

ParameterTypeDescription
hasConsentedBooleanSet visitor consent for private data usage. When false some features will be deactivated, cache will be deactivated and cleared.
Visitor visitor = Flagship.newVisitor("visitor_unique_id").build();
  visitor.setConsent(false);

🚧

When consent is not given: Hits, Activations will be deactivated and all the cached visitor data will be cleared until consent is given again.
Only consent tracking requests will enabled in order to clear server-side cached data.

Managing visitor cache

The cache manager helps to cache visitors data, to cache hits not sent due to internet failures or server errors, to cache campaign assignations for offline mode and to prevent reallocation in Bucketing mode. Indeed, as the assignation is made on local device in bucketing mode, changing campaign allocation in the platform without a cache, would make visitors to see different campaigns.

The Flagship Java SDK includes a ready-to-use cache implementation using a local SQLite database. It is recommended to use it on environments that only manage one visitor at a time (client) and therefore it is not implemented by default.

For environments that manage multiple visitors at the same time (server) it is possible to provide a custom cache implementation using the following abstract class and the specific interfaces:

// Use the included ready-to-use local SQlite implemenation. (Client environments only)

Flagship.start("_ENV_ID_", "_API_KEY_", new FlagshipConfig.DecisionApi()
                        .withCacheManager(new SQLiteCacheManager()));

// Use a custom implementation to connect with your own database. (Server environments)
        Flagship.start("_ENV_ID_", "_API_KEY_", new FlagshipConfig.DecisionApi()
                .withCacheManager(new CacheManager.Builder()
                        .withVisitorCacheLookupTimeout(200L)
                        .withHitCacheLookupTimeout(200L)
                        .withVisitorCacheImplementation(new IVisitorCacheImplementation() {
                            @Override
                            public void cacheVisitor(String visitorId, JSONObject data) throws InterruptedException {
                                // Upsert in your database.
                            }

                            @Override
                            public JSONObject lookupVisitor(String visitorId) {
                                // Find in your database.
                                return null;
                            }

                            @Override
                            public void flushVisitor(String visitorId) {
                                // Clear data from your database.
                            }
                        })
                        .withHitCacheImplementation(new IHitCacheImplementation() {
                            @Override
                            public void cacheHit(String visitorId, JSONObject data) {
                                // Insert hit in your database.
                            }

                            @Override
                            public JSONArray lookupHits(String visitorId) {
                                // Find and delete in your database.
                                return null;
                            }

                            @Override
                            public void flushHits(String visitorId) {
                                // Clear data from your database.
                            }
                        })
                        .build()));

interface IVisitorCacheImplementation

This interface specifies the methods to implement in order to cache visitors information.

public JSONObject lookupVisitor(String visitorId)

This method is called when the SDK needs to get visitor information from your database. This method will block the current thread so it will be called with a configurable timeout. See Cache format section.

ParameterTypeDescription
visitorIdStringVisitor unique identifier from which data need to be loaded.

Return : visitor information json respecting the expected format.

public void flushVisitor(String visitorId)

This method is called when the SDK needs to flush visitor information in your database. For example when the user hasn't given his consent this method will be called.

ParameterTypeDescription
visitorIdStringVisitor unique identifier from which hits need to be cached.
dataJSONObjectdata to cache

public JSONArray lookupHits(String visitorId)

This method is called when the SDK needs to get visitor hits from your database in order to send them again. This method will block the current thread so it will be called with a configurable timeout. See Cache format section.

ParameterTypeDescription
visitorIdStringVisitor unique identifier from which hits need to be loaded.

Return : visitor hits json array respecting the expected format.

🚧

Hits must be deleted

Cached hits must be deleted before being returned from lookupHits so it prevents hits cache duplication if they failed to be sent again.

This method is called when the SDK needs to flush visitor hits in your database. For example when the user hasn't given his consent this method will be called.

ParameterTypeDescription
visitorIdStringVisitor unique identifier from which hits need to be cleared.

Experience Continuity

In some situations, you may want experience consistency between an anonymous visitor and an authenticed visitor. Flagship provides the following two methods in order to help you to specify when a visitor is authenticated or not.

Authenticate

public void authenticate(visitorId: String)

ParameterTypeDescription
visitorIdStringid of the new authenticated visitor.

Unauthenticate

public void unauthenticate()

Code example

Visitor visitor = Flagship.newVisitor("visitor_unique_id").build(); // anonymous visitor lands on your app.

  // Once the visitor log in and is authenticated on your app.
  visitor.authenticate("visitor_id");


  // Once the visitor log out and is unauthenticed on your app.
  visitor.unauthenticate();

Hit Tracking

Appendix

Predefined user context keys : FlagshipContext

The Flagship SDK contains predefined user context keys.

The keys marked as Yes in the Auto-set by SDK column will be automatically set, while the ones marked as No need to be set by the customer.

📘

Check the values sent by the SDK by enabling the logs.

You can overwrite these keys at any time. The key-value pairs will be sent to the server in the user context and can be edited in the Persona section of the Flagship platform.
