Usage
|
|
host_bcp <image> [--use-first-dir] | xargs <art-host-tool> ...
|
|
Extracts boot class path locations from <image> and outputs the appropriate
|
|
--runtime-arg -Xbootclasspath:...
|
|
--runtime-arg -Xbootclasspath-locations:...
|
|
arguments for many ART host tools based on the \$ANDROID_PRODUCT_OUT variable
|
|
and existing \$ANDROID_PRODUCT_OUT/apex/com.android.art* paths.
|
|
If --use-first-dir is specified, the script will use the first apex dir instead
|
|
of resulting in an error.
