Fixed

Catch SecurityException when thrown on call to getNetworkCapabilities used to detect current network availability. (#129)
Explicitely flag PendingIntents as FLAG_IMMUTABLE on Android SDK versions that support doing so. Explicitly specifying mutability is required when targeting Android S+. (#133)

## [2.14.2] - 2021-06-02 ### Fixed - Added check to prevent `NullPointerException` in `DiagnosticEventProcessor.stopScheduler` when `LDClient.close` is called before the application is foregrounded when the SDK was initialized in the background. ([#127](#127)) - Log message warning that JSON flag was requested as a String has been updated to include the key of the flag requested to assist in discovering which flag is being requested with an unexpected type.

… Android S+ (#213)

* Add support for TLS 1.2 on API 16+ * Add back final keyword * Bumping the minSdkVersion from 15 to 16 * Circle CI 2.0 * Created new branch for multi-environment sdk feature * Stub out new LDConfig and LDConfig.Builder code for multi-environment. * Added overloaded init method in LDClient for creating secondary instances * Added getForMobileKey methods * Added LDClient init test for secondary environment, added exception to getForMobileKeys, added multi-environment support to setOffline and setOnlineStatus (seems naive, needs testing), and added exceptions to LDConfig setSecondaryMobileKeys * Move primary instance into general instances map. Begin on methods effecting all instances. * Removed incorrect LDClient test * Fixed 1 failing test in LDClient, added multi-environment test file, fixed some linter issues * Removed unnecessary ListenableFuture in LDClient init, changed identify method for multi-environment, not sure about SettableFuture null vs null for return type of Future<Void>, both type check and pass tests * Added setOnlineStatus multi-environment changes * Moved primaryEnvironmentName to LDConfig, simplifying by removing primaryKey separation everywhere but the builder. Add getRequestBuilderFor a specific environment. Add static method to LDClient to get all environment names so that environments can be iterated over.

Reformatted interfaces. Removed unused imports. * Handle null case in allFlags, actually commit changes to UserManager. * Hopefully fix edge cases in summary event reporting to pass testing. * Hopefully fix edge cases in summary event reporting to pass testing. * Simplify getFeaturesJsonObject as no longer using -1 as placeholder for null for variations. * Make Flag non-mutable.

This caused a race condition in repeated stream restarts that could put the SDK in a bad state. * Change LDAwaitFuture to not treat zero timeout as unlimited timeout Treating a timeout of zero as unlimited caused a change in behavior when initializing the SDK. This update restores the behavior init had when zero was passed as the timeout argument from pre-2.8.0.

This caused a race condition in repeated stream restarts that could put the SDK in a bad state. * Change LDAwaitFuture to not treat zero timeout as unlimited timeout Treating a timeout of zero as unlimited caused a change in behavior when initializing the SDK. This update restores the behavior init had when zero was passed as the timeout argument from pre-2.8.0.

This caused a race condition in repeated stream restarts that could put the SDK in a bad state. * Change LDAwaitFuture to not treat zero timeout as unlimited timeout Treating a timeout of zero as unlimited caused a change in behavior when initializing the SDK. This update restores the behavior init had when zero was passed as the timeout argument from pre-2.8.0. Also improves handling of spurious wakeups, and includes test cases for LDAwaitFuture. * Revert "Merge remote-tracking branch 'remotes/origin/experiment' into next-release" This reverts commit 3ac167f, reversing changes made to d26e006. * CircleCI fixes (#131) * Better ci fix (#132) * Speedup tests by building on macOS (#137) * Background identify fixes (#133) Add new testing controllers for network and foreground states.

Reformatted interfaces. Removed unused imports. * Handle null case in allFlags, actually commit changes to UserManager. * Hopefully fix edge cases in summary event reporting to pass testing. * Hopefully fix edge cases in summary event reporting to pass testing. * Simplify getFeaturesJsonObject as no longer using -1 as placeholder for null for variations. * Make Flag non-mutable.

Reformatted interfaces. Removed unused imports. * Handle null case in allFlags, actually commit changes to UserManager. * Hopefully fix edge cases in summary event reporting to pass testing. * Hopefully fix edge cases in summary event reporting to pass testing. * Simplify getFeaturesJsonObject as no longer using -1 as placeholder for null for variations. * Make Flag non-mutable.
