|
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.
