- Code additions to download data from Google Play Store if not on device
- Changes deploy to write new meta-data
- Changes to Android deploy to cache ini files once and re-read instead of the constant open/read we had
- Added template/code generation system so we can now generate Java files based on a template for project dependent names etc

Original Notes (adapted)
Implementation and Integration of Oculus Audio SDK for VR Audio Spatialization
- Adding new audio extension which wraps the oculus audio sdk and the new XAPO plugin
- Adding new XAPO (Xaudio2 Audio Processing Object) effect for processing mono audio source streams inside the new module
- Added new enumeration which allows users to select which spatialization algorithm to use for spatialized mono sources
- Refactored the regular sound source spatialization/effect in XAudio2 device code to support the new HRTF mono-to-stereo effect
- Designed feature so that if the sound spatialization module isn't used, the spatialization will default to normal spatialization algorithm
Notes on implementation:
- Because the audio engine doesn't bifurcate spatialized vs. non-spatialized sound sources into separate source pools, I had to create up-front the effects for the full number of supported sounds 32). This is because the oculus sdk requires at initialization the total number of sound sources that will be used in the SDK.
- Because the oculus SDK refers to sound source instances by index (into the pre-allocated array of sources set at init), I had to save each sound source's index so that it can be used on the HRTF XAPO effect, and then piped to the oculus SDK inside the UE audio extension.
- The audio engine assumes that mono-sources will be treated a certain way (during send-routing and spatialization). Because this new HRTF effect is effectively turning mono-sources into stereo-sources, some code had to be changed to send/route these audio sources as if they were stereo.
- This implementation is slightly different than the original GDC implementation to better work with multiple audio devices. Each audio device creates an IAudioSpatializationAlgorithm object which contains the oculus HRTF processing contexts.

Rob asked me to back out GENERATED_*_BODY -> GENERATED_BODY change for now until the "_Validate and _Implementation auto-generation" discussion is over.

- Created audio device manager which manages weak ref handles to audio devices
- Audio device handles are created with WorldContexts and accessed through UWorld objects
- All access to audio devices are now through audio device handles
- There is a main/default audio device for GEngine for use with the Editor and single worldcontext games

- Removed all the OBBInAPK hackery in UBT
- Updated the apk install scripts with some more information as to what it's doing [UE-8258]
[CL 2420664 by Josh Adams in Main branch]
- Moved some Android settings to ProjectSettings, re-enabled SDK settings
- Removed SigningConfig.xml, and moved those settings into project settings
- Added concept of NotForLicensees and NoRedist engine and project config settings
- Removed BaseInternalGame.ini, replaced with NotForLicensees/BaseGame.ini
- Moved User*.ini to end of .ini hierarchy
- Added support for CLASS_GlobalUserConfig, so their settings will be saved to <AppData>/.../User*.ini (useful for SDK paths, etc)
- Enabled AndroidPlatformEditor module on Mac
- Changed Mac Build.sh to allow for Android on the commandline (just pass through if it's not an Xcode platform name)
- Iterative Android packaging now looks at just the important .ini sections, NOT entire .ini files

- Enabled ES31 for GitHub/P4 users (currently only works on a Tegra K1 with recent system software)
- Always use separate APKs - this means that all APKs will have -armv7-es2 (or whatever) in their name. This may affect scripts, etc people have written
- Fixed a bug when using multiple java libraries (for users who add their own libs)
- Properly collapse Android devices into a single device with multiple variants. LaunchOn will now choose the best format based on the connected device. If you want to override the format, you will need to use the ProjectLauncher
- Added Android serial number to the device type, in case you have multiple devices of the same type (also fixes [UE-3770])

Android fixes for workflow and threading issues.
Receipt is now returned as part of the IAP product information in blueprints
IAP workflow in blueprints now use an IAP request object as opposed to just a string.
Changes to the IOS workflow to accommodate receipts in product responses.
Android game activity has been updated to receive onActivityChanged messages. Needed for routing activity changes to android IAP.
A lot of threading fixes
Fixes for certain google events not calling the appropriate delegates.
Play store license key property added to runtime settings.

Removed GVolumeMultiplier and added an equivalent to FApp to contain the code to load the unfocused volume multiplier from config.
UE-4449 - Allow users to choose whether audio can be heard when focus is lost

- Fixes looping issue with ADPCM samples
- Fixes Android not looping sound cues correctly
- Fixes one shot sound ADPCM problems where sound would get cut early
- Removed Android Audio Device update function - was never called and did nothing anyway so this will improve clarity
Changed ADPCM decompressor so that it uses the same code to decompress a full file as it does when streaming - old code was correct it was just silly have it duplicated.
