''' This script can be run with no arguments, in which case it will produce an APK with native libraries for all four architectures: arm, arm64, x86, and x64. You can instead list the architectures you want as arguments to this script. For example: python make_universal_apk.py arm x86 The environment variables ANDROID_NDK and ANDROID_HOME must be set to the locations of the Android NDK and SDK. Additionally, `ninja` should be in your path. It assumes that the source tree is in the desired state, e.g. by having run 'python tools/git-sync-deps' in the root of the skia checkout. Also: * If the environment variable SKQP_BUILD_DIR is set, many of the intermediate build objects will be places here. * If the environment variable SKQP_OUTPUT_DIR is set, the final APK will be placed in this directory. * If the environment variable SKQP_DEBUG is set, Skia will be compiled in debug mode.
