New APIs and capabilities

• Added new quality prediction API. If using default fidelity parameters, this API can be enabled through Window > Android Performance Tuner > Prediction Settings. If using custom fidelity parameters, Prediction Settings tab instead details how the predictability API can be used.
• Added a new option to disable advanced telemetry collection to improve performance on low end devices. This option can be accessed from Window > Android Performance Tuner > Settings > Disable Async Telemetry.

Other changes

• Migrated Protobuf library to Protobuf lite.

Bug fixes

• Fixed getpid returning 0 while trying to get memory telemetry.
• Stopped StopLoadingGroup from executing without an active loading group.
• Fixed a bug where the library crashes if max instrumentation keys are more than histogram count.

Other changes

• The Utilities folder has been moved to the Samples~ folder. If you're importing Android Performance Tuner from .tgz you'll be able to import the sample scripts from the Package Manager. If you're using the .unitypackage, also import the android-performance-tuner-{version}-samples.unitypackage.

Bug fixes

• Fixed #27: removed scripting define symbols from Initializer
• Fixed #28: LoadingSceneTracker has now been moved to the Samples~ folder

New APIs and capabilities

• Introduced support for Addressables scenes in Unity 2019.3 or newer.
• Introduced LoadingSceneTracker to automatically track loading times in loading scenes.
• Introduced option in APT window to disable verbose logging in Unity Console (disabled by default).
• Introduced option in APT window to hide some sensitive information from logging in the C/C++ libraries (hidden by default).

Breaking changes

• Importing the APT package in Unity 2017 now requires extra steps as detailed here.
• Importing the APT package after removing it from the project now requires deleting the ANDROID_PERFORMANCE_TUNER_UTILITIES symbol under Project Settings > Player > Other Settings > Scripting Define Symbols (details here).

Other changes

• Fixed #22: Proto compilation won't open a new window.

Bug fixes

• Fixed #24: SetupConfig not using Unity separator on Windows.

We're changing the version numbering of APT Plugin to match that of native
Android Performance Tuner. Hence, this release will be 1.5.0 instead of 1.2.1.

New APIs and capabilities

• Added support for x86-64 platforms.

Bug fixes

• Fixed a bug for which Annotations and FidelityParams were reset when importing a project.
• Fixed a bug that reset instrumentation settings to default when closing Unity.

New APIs and capabilities

• Updated the native library to version 1.5.0.
• Aggregation strategy and frequency can now be set programmatically.

Bug fixes

• Fixed a bug that prevented successful authentication with a correct API key.

New APIs and capabilities

• Editor page with Integration Steps.

Deprecations

• LoadingState is obsolete, you should stop using loading annotation and use new loading API instead.

New APIs and capabilities

• Updated the native library to version 1.3.11.

Bug fixes

• Fixed loading time and duration recording on devices with inconsistent CLOCK_BOOTTIME.

New APIs and capabilities

• Updated the native library to version 1.3.8.
• Lifecycle events are now automatically recorded to detect crashes.
• More memory metrics are now recorded when EnableMemoryRecording(true) is called.
• Added void SetMetricLimits(MetricLimits metricLimits). This function updates the memory model so that the maximum number of metrics of each type is now specified at startup, rather than allocating space for all possible annotation combinations.
• Updated loading times capabilities with the new functions Result<ulong> StartRecordingLoadingTime(LoadingTimeMetadata eventMetadata, TAnnotation annotation) and ErrorCode StopRecordingLoadingTime(ulong handle), which you can call to record annotated loading time events. Using these functions automatically record the time from app startup to Start() and the first tick.
• Loading events must now be grouped with calls to StartLoadingGroup and StopLoadingGroup.
• When a player backgrounds a game during loading, an event is sent for later analysis of loading abandonment.

Breaking changes

• Google.Android.PerformanceTuner_gen.asmref is automatically created inside the AndroidPerformanceTuner/Runtime folder.
• Upload callback is not enabled by default. Use the new function EnableUploadCallback() to receive callbacks.

Bug fixes

• Fixed #1: The UI now provides an additional message if the protoc file couldn't be opened.
• Fixed #2: Changed the menu path to be consistent with other Google products.
• Fixed #3: The assembly definition file (.asmdef) is now automatically created for a generated folder.
• No upload on metered connections.
• Calling Flush will immediately upload data rather than queuing it for later upload.
• Fixed intermittent upload failure due to JSON formatting of times.
• Fixed a problem with uploads on release builds.
