Options:
--bs Compare methods body size
-c, --comment=VALUE Comment to be saved inside description file
--descrease-is-regression
Report also size descrease as regression
-e, --entry=PATTERN Process only entries matching regex PATTERN
-f, --flat Display flat comparison of entries, without
showing comparison of their content
-h, --help, -? Show this message and exit
--keep-uncompressed-assemblies
Save LZ4 uncompressed assemblies to temporary files
--md Compare metadata sizes
--test-apk-size-regression=BYTES
Check whether apk size increased more than BYTES
--test-assembly-size-regression=BYTES
Check whether any assembly size increased more
than BYTES
--test-apk-percentage-regression=PERCENT
Check whether the apk size increased by more than
PERCENT
--test-content-percentage-regression=PERCENT
Check whether any individual file size increased
by more than PERCENT
-s, --save-descriptions Save .[apk|aab]desc description files next to the
package(s) or to the specified path
--save-description-1=PATH
Save .[apk|aab]desc description for first package
to PATH
--save-description-2=PATH
Save .[apk|aab]desc description for second package
to PATH
--summary-only Output only summary information
-v, --verbose Output information about progress during the run
of the tool
It can be use to compare Android packages (apk's) and/or apk descriptions files (apkdesc)
