Dumps a summary of the compressed and uncompressed sizes of various |
|
types of files in each package. Emits one line per package. |
|
Packages must be zipfiles, readable using "unzip". |
|
|

Example output line: |
|
|
|
filesize=642684 all=603288/919304 dex=119529/353815 name="out/App.apk" |
|
|
|
filesize: the size of the package on disk |
|
name: the name of the package as passed to $PROGNAME |
|
|
|
These fields are presented as <uncompressed bytes>/<compressed bytes>: |
|
|
|
all: the sum of all entries in the package |
|
dex: the sum of all "*.dex" entries in the package |
