gn_to_bp: wrap defines in ifndef create_apk.py assumes you are either run from the aosp tree, or you are being run from make_universal_apk.py, which now defers to create_apk.py for all functionality, even argument parsing. tools/skqp/generate_gn_args moved some functionity into skqp_gn_args.py, which is now used by create_apk.py create_apk now accepts android sdk license for you. create_apk and make_universal_apk.py now are better about cleaning up after exceptions happen. Old script make_apk.sh now just points at make_universal_apk.py CQ_INCLUDE_TRYBOTS=skia.primary:Build-Debian9-Clang-x86-devrel-Android_SKQP,Test-Debian9-Clang-NUC7i5BNK-CPU-Emulator-x86-devrel-All-Android_SKQP Change-Id: I2dba20ef7017987cabb2bd49f070e2b1594785d5 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/235678 Reviewed-by: Ben Wagner <bungeman@google.com> Commit-Queue: Hal Canary <halcanary@google.com>
