| 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 create_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. |
| |
| We also assume that the 'resources' directory has been copied to |
| 'platform_tools/android/apps/skqp/src/main/assets', and the |
| 'tools/skqp/download_model' script has been run. |
| |
| 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. |
