The purpose of this is to be able to use the native graphics code from the Android platform directly in Android Studio (running on desktop) to do layout rendering. This creates a host library that is a subset of libandroid_runtime including only the JNI files relevant to Android graphics. It also includes LayoutlibLoader.cpp which is used to load the JNI when using it as part of layoutlib (the graphics library for Android Studio). This also creates libhwui-host, a host library that is a subset of libhwui. Bug: 117921091 Test: lunch sdk && m libandroid_runtime Change-Id: I3850020d2d4c13c85e377476bc463d3eb6a01c6d
