7This script can be run with no arguments, in which case it will produce an
8APK with native libraries for all four architectures: arm, arm64, x86, and
9x64.  You can instead list the architectures you want as arguments to this
10script.  For example:
11
12    python make_universal_apk.py arm x86
13
14The environment variables ANDROID_NDK and ANDROID_HOME must be set to the
15locations of the Android NDK and SDK.
16
17Additionally, `ninja` should be in your path.
18
19It assumes that the source tree is in the desired state, e.g. by having
20run 'python tools/git-sync-deps' in the root of the skia checkout.
21
22Also:
23  * If the environment variable SKQP_BUILD_DIR is set, many of the
24    intermediate build objects will be placed here.
25  * If the environment variable SKQP_OUTPUT_DIR is set, the final APK
26    will be placed in this directory.
27  * If the environment variable SKQP_DEBUG is set, Skia will be compiled
28    in debug mode.
