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_HOME 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 placed 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.
