Android-SDK - 2.0.0-beta3
## 2.0.0-beta3
June 12, 2018
This beta release of the Optimizely SDK introduces APIs for Feature Management.
### New Features * Introduces the `isFeatureEnabled` API to determine whether to show a feature to a user or not. ``` Boolean enabled = optimizelyClient.isFeatureEnabled("my_feature_key", "user_1", userAttributes); ```
* You can also get all the enabled features for the user by calling the following method which returns a list of strings representing the feature keys: ``` ArrayList enabledFeatures = optimizelyClient.getEnabledFeatures("user_1", userAttributes); ```
* Introduces Feature Variables to configure or parameterize your feature. There are four variable types: `Integer`, `String`, `Double`, `Boolean`. ``` String stringVariable = optimizelyClient.getFeatureVariableString("my_feature_key", "string_variable_key", "user_1"); Integer integerVariable = optimizelyClient.getFeatureVariableInteger("my_feature_key", "integer_variable_key", "user_1"); Double doubleVariable = optimizelyClient.getFeatureVariableDouble("my_feature_key", "double_variable_key", "user_1"); Boolean booleanVariable = optimizelyClient.getFeatureVariableBoolean("my_feature_key", "boolean_variable_key", "user_1"); ``` * Live variable accessor methods have added back in for backward compatibility.
* Support for all Full Stack project types.
### Breaking changes * The `track` API with revenue value as a stand-alone parameter has been removed. The revenue value should be passed in as an entry of the event tags map. The key for the revenue tag is `revenue` and will be treated by Optimizely as the key for analyzing revenue data in results. ``` Map eventTags = new HashMap();
// reserved "revenue" tag eventTags.put("revenue", 6432);
optimizelyClient.track("event_key", "user_id", userAttributes, eventTags); ```
* We have removed deprecated classes with the `NotificationBroadcaster` in favor of the new API with the `NotificationCenter`. We have streamlined the API so that it is easily usable with Java Lambdas in *Java 1.8+*. We have also added some convenience methods to add these listeners. Finally, some of the API names have changed slightly (e.g. `clearAllNotifications()` is now `clearAllNotificationListeners()`)
### Bug Fixes * Fix for the following issue: https://issuetracker.google.com/issues/63622293 Our github issue is [here](https://github.com/optimizely/android-sdk/issues/194). The JobWorkService was probably destroyed but we didn't cancel the processor. It causes an exception in dequeueWork in our JobWorkService. We wrapped the dequeueWork with a try/catch and are also now cancelling the background task in onDestroy.
* Fix for possible error when loading logger via dagger (fall back logger provided).
* Load UserProfileService on synchronous start. Also, cleanup UserProfileService cache in the background thread by removing experiments that are no longer in the datafile.
