Revent files should now start with REVENT followed by the file format version. – Added support for gamepad recording. This type of recording contains only the events from a gamepad device (which is automatically identified). – A mode field has been added to the recording format to help distinguish between the normal and gamepad recording types. – Added -g option to record command to expose the gamepad recording mode. – The structure of revent code has undergone a major overhaul to improve maintainability and robust- ness. – More detailed info command output. – Updated Makefile to support debug/production builds. • Android API: Upgraded Android API level from 17 to 18. • uiautomator: The window hierarchy is now dumped to a file when WA fails on android devices. • AndroidDevice: – Added support for downgrading when installing an APK. – Added a broadcast_media_mounted method to force a re-index of the mediaserver cache for a specified directory. – Now correctly handles None output for get_pids_of() when there are no running processes with the specified name. – Renamed the capture method from capture_view_hierachy to capture_ui_hierarchy. – Changed the file extension of the capture file to .uix – Added -rf to delete_files to be consistent with LinuxDevice. • LinuxDevice: Now ensures output from both stdout and etderr is propagated in the event of a DeviceError. • APKWorkload: – Now ensure APKs are replaced properly when reinstalling. 6 Chapter 1. What’s New Workload Automation Documentation, Release 2.7.0 – Now checks APK version and ABI when installing. – Fixed error on some devices when trying to grant permissions that were already granted. – Fixed some permissions not being granted. – Now allows disabling the main activity launch in setup (required for some apps). – Added parameter to clear data on reset (default behaviour unchanged). – Ignores exception for non-fatal permission grant failure. – Fixed issue of multiple versions of the same workload failing to find their APK. – Added method to ensure a valid apk version is used within a workload. – Updated how APK resolution is performed to maximise likelihood of a workload running. – When check_apk is True will prefer host APK and if no suitable APK is found, will use target APK if the correct version is present. When False will prefer target apk if it is a valid version otherwise will fallback to host APK. • RunConfiguration: Fixed disabling of instruments in workload specs. • Devices: – Added network connectivity check for devices. – Subclasses can now set requires_network to True and network connectivity check will be performed during setup(). • Workloads: – Added network check methods. – Fixed versions to be backwards compatible. – Updated workload versions to match APK files. – Fixed issues with calling super. • Assets: Added script to retrieve external assets for workloads. • Execution: Added a clean_up global config option to delete WA files from devices. • Runner: No longer takes a screenshot or dump of UI hierarchy for some errors when unnecessary, e.g. host errors. • core: Constraints and allowed values are now checked when set instead of when validating. • FpsProcessor: – Added requirement on filtered_vsyncs_to_compose for total_vsync metric. – Removed misleading comment in class description. • BaseUiAutomation: Added new Marker API so workloads generate start and end markers with a string name. • AndroidUiAutoBenchmark: Automatically checks for known package versions that don’t work well with AndroidUiAutoBenchmark

I’m willing to go thermonuclear war on this. —Steve Jobs, Apple Inc. Android, Inc. started with a clear mission by its creators. According to Andy Rubin, one of Android’s founders, Android Inc. was to develop “smarter mobile devices that are more aware of its owner’s location and preferences.” Rubin further stated, “If people are smart, that information starts getting aggregated into consumer products.” The year was 2003 and the location was Palo Alto, California. This was the year Android was born. While Android, Inc. started operations secretly, today the entire world knows about Android. It is no secret that Android is an operating system (OS) for modern day smartphones, tablets, and soon-to-be laptops, but what exactly does that mean? What did Android used to look like? How has it gotten where it is today? All of these questions and more will be answered in this brief chapter. Origins Android first appeared on the technology radar in 2005 when Google, the multibillion- dollar technology company, purchased Android, Inc. At the time, not much was known about Android and what Google intended on doing with it. Information was sparse until 2007, when Google announced the world’s first truly open platform for mobile devices. The First Distribution of Android On November 5, 2007, a press release from the Open Handset Alliance set the stage for the future of the Android platform.

It was first released as a Android Beta Program build on March 9 , 2016 with factory images for current Nexus devices, which allows supported devices to be upgraded directly to the Android Nougat beta via over-the-air update. Nougat is introduced as notable changes to the operating system and its development platform also it includes the ability to display multiple apps on-screen at once in a split- screen view with the support for inline replies to notifications, as well as an OpenJDK-based Java environment and support for the Vulkan graphics rendering API, and "seamless" system updates on supported devices. Keywords: jellybean, kitkat, lollipop, marshmallow, naugat I. Introduction This research has been done to give you the best details toward the exciting new frontier of open source mobile development. Android is the newest mobile device operating system, and this is one of the first research to help the average programmer become a fearless Android developer.

Compute Benchmark scores are used to evaluate and optimize GPU Compute performance using workloads that include image processing, computational photography, computer vision, and machine learning.

Each workload is run for 20 iterations by default. September 2019 "5 Scores Geekbench 5 provides one overall score for the Compute Benchmark. The overall score is the geometric mean of the scores of the individual Compute workloads. Comparing Scores Each Compute workload has an implementation for each supported Compute API. While it is possible to compare scores across APIs (e.g., a OpenCL score with a Metal score) it is important to keep in mind that due to the nature of Compute APIs, the performance difference can be due to more than differences in the underlying hardware (e.g., the GPU driver can have a huge impact on performance).!
