Subject: android: Use NDK structure for third party modules
X-Git-Tag: upstream/1.1.92~721
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0dc620ef57978644037c6c593a71f6cb6c43757e;p=platform%2Fupstream%2FVulkan-Tools.git

android: Use NDK structure for third party modules

Locate glslang and spirv directories under shaderc directory.
This allows the layers build to optionally use the NDK sources.
For glslang and spirv and shaderc-
 Use LOCAL_STATIC_LIBRARIES instead of LOCAL_C_INCLUDES to find headers.
 Use import-module instead of PREBUILT_STATIC_LIBRARY.

 ### Build steps for Android
+
+There are two options for building the Android layers. One using the SPIRV tools
+provided as part of the Android NDK or build using upstream sources.
+To build with SPIRV tools from the NDK, remove the build-android/third_party directory created
+by running update_external_sources_android.sh, (or never run update_external_sources_android.sh).
 Use the following script to build everything in the repo for Android, including validation layers, tests, demos, and APK packaging:
+This script does retrieve and use the upstream SPRIV tools.
