[Tool][Win] GOptimize v1.44 (BASH script for CYGWIN)

Great tool thanks! I've found many apk's with thumbs.db file hidden in it. If you use jpegtran on the jpg files, you may also reduce a lot of size.

Well, it's jpegtran -optimize feature looks promising for reducing few more kBs
Thanks =)
Will try on an apk and see if android has problem with optimized jpgs...

Do you know any APP with JPG's?

You can... but you can't remove debug info from odexed jar because there is no dex file in it...

Thank you

In case of a user app should I use -b with the number of my phone API level or with the highest API level number for which the app is written?

I use API Level of my Rom, 15 for ICS...
I made removing debugging info Fail-Safe, if there are any errors in the process script will inform you that removing debug info is failed and revert to original classes.dex...
Didn't test lower API Levels...

Found even better tool for optimizing jpegs https://github.com/tjko/jpegoptim XD

Coming soon in v1.23 =)

Code:

I get this error

Is it Java config error? i did configure it properly

also tried removing '-b'(remove debugging) option but some error with testkey

Try removing new line character from bin/.JavaPATH if you have it, if you still get error then Java version is to low or Java is incorrectly installed.
Try installing latest Java 1.7, you will also have to put new Java bin path in bin/.JavaPATH if you had 1.6 or lower before...

gu5t3r · Sep 25, 2013 at 6:35 PM

Just checked if there is new line after Java bin path it does not recognize Java at all
Edited script to read only first line if there are multiple lines in bin/.JavaPATH

Will be fixed in v1.23, for now if you have new line in .JavaPATH remove it

But, I still think your problem is bad Java installation or old Java version

You should always edit GOptimize files with Notepad2 or Notepad++ because windows notepad does not recognize unix files correctly...

i dont have a newline in .Java PATH and i do use Notepad++

this' what my java folder looks like

I Gave path as

Code:

C:\Program Files\Java\jre7\bin

and also tried

Code:

C:\Program Files\Java\jre6\bin

manualGo.cmd detects 'which java' and gives the right path though!

BUt have the Same Problem!

Changelog: 2013-09-25 v1.23

Added -j option to optimize jpg images in apk using jpegoptim
-j0 is lossless optimization and is recommended; it only strips unnecessary info from jpg (like which app is used to create it) and optimizes huffman coding
If you want to lower jpg's size even more, use -j95 which will recompress jpg's (and optimize) that are unnecessary big and only perform lossless optimization on others.
Every JPG compression guide agrees that compression level above 95 is pointless and creates unnecessary big jpg's.
I also left you choice to choose compression level between [75-100]
Reworked code for APK recompressing for easier adding of file extensions/formats that should always be uncompressed
Also added zip and lzma to that list
Improved reading Java bin path from bin/.JavaPATH
Removed "Packing PNG's" info line after optimizing pngs; don't worry, optimized png's are still packed in apk

Code:

$ goptimize -j0 *.apk

Hi,

Have you try to put the root of E:\ ? (just e:\goptimize)
I saw it's a long way and a "!" in the way.
Running here perfectly on win7 but 32bit java version.

I found solution, it's to turn history expand off...
v1.24 will work in your path...

:victory:

Changelog: 2013-09-26 v1.24

Added jpe and jfif extensions to search list when optimizing jpg's which now is: jpg, jpeg, jpe, jfif.
Found and FIXED bug where files with no extension were not recompressed on -r option
ReWorked some compression code for easier reading and editing
Paths containing '!' (exclamation mark) will no longer be problem for script.
Minor code improvements...
You can now write -zo instead -zb if you like, it's easier for me =)
Updated smali v2 to 2.0b6 which can now remove debug info from some bitchy classes.dex which smali 1.4.2 and 2.0b5 couldn't.
