I had been messing about with a script to pull apks off my phone, zipalign them and then push them back, but then I saw wesgarner's CM build with a binary and script for use on your phone. I don't really want to mess round with flashing a ROM just for that though, so I've ripped them out and uploaded them below. Another reason is I want to run this manually (with GScript) rather than on boot (as it does in wesgarner's ROM).
I take no credit for this, the binary and script were both taken from wesgarner's CM buiild.
To "install" this, just adb push the two files in the zip below onto your phone with:
Code:
adb shell mount -o remount,rw /system
adb push zipalign /system/bin
adb push zipalign_apks /system/sd/zipalign_apks.sh
adb shell chmod 755 /system/bin/zipalign /system/sd/zipalign_apks.sh
adb shell mount -o remount,ro /system
Then anytime you want to run the script just do:
Code:
adb shell sh /system/sd/zipalign_apks.sh
Or in terminal:
Code:
su
sh /system/sd/zipalign_apks.sh
Has been tested on CM 4.2.7.1

i do not even know what zipalign does .. but i did add this to my script
# lucid -z
so .. what does it do exactly?

Sweet... Thanks...
I was surprised that more than half of the Apps I have were already ZipAligned...

APKs (as you probably already know) are just zip files. zipalign simply aligns the APK on 4-byte boundaries which Android is more efficient wrt memory access.

Since the 1.6 SDK was released, the ADT does this automatically on APK export. Therefore any app which has been updated since ~September (and was developed using the ADT Eclipse plugin) will be zipalign'd. I was more surprised that 12 out of the 43 apps on my phone weren't aligned!

that's awesome .. thanks for the link .. i hadn't read about that

Thanks much for this!
Here is a simple gscript to install zipalign after a wipe or new build flash.
You must first create directory /sdcard/zipalign and place zipalign from the zip in the OP there. Path to the file should now be /sdcard/zipalign/zipalign.
Place this script in your gscript folder (after removing .txt from the name) and load it in gscript with su permissions.
I also find it easier to run the script in the zip from the OP in Gscript as well. Instead of placing it in /system/sd run this (assumes zipalign_apks.sh is at root of C:\)
Code:
adb remount
adb push C:\zipalign_apks.sh /sdcard/gscript/zipalign_apks.sh
Then just load it into Gsrcipt with su permissions as with the other script.
Easiest of all may just be to use the commands within Lucid's script. But, I'm comfortable with Gscript, and I can make it 2 clicks away.
EDIT: First execution, you may want to run the original way, because guess what? Gscript isn't zipaligned. But it worked fine just the same.

worked great thanks.

Thanks. I didn't want to flash whole ROM to zipalign apps, so script was very handy.
Actually I've zipaligned only 2 apps, one of them was everybody loved Linda

so anyone wanna bless me with a terminal code to install the script?

I put a quick explanation of my script on my ROM page: here ya go (rough explanation)
Zip Align reduces the amount of RAM used during processing running for a major speed increase in dex-opt and running the apps, along with the RAM hack and a CC (or your userinit) boots speeds incredibly and better usability of apps (boot and system) in Android: http://developer.android.com/guide/d.../zipalign.html
Most developers have not used this yet (CM does ZipAlign his apps), but this does for the system apps provided from the now old Google Apps

it will really, it doesn't detect the diff
Also, SDK4 didn't really include an enforced ZipAlign like SDK5 (eclair) does
Plus I built the ZipAlign from source from eclair - so this script may not update them all perfectly

Unzip the files to your SD Card, then:
Code:
su
mount -o remount,rw /system
mv /sdcard/zipalign /system/bin
mv /sdcard/zipalign_apks /system/sd/zipalign_apks.sh
chmod 755 /system/bin/zipalign /system/sd/zipalign_apks.sh
mount -o remount,ro /system

Post deleted becoz it was redundant

can someone make a script for windows or a bat file that can zipalign a batch of apks? I am not that ofay with line commands and when i create a new theme (which i often do), i then have to go and zipalign every single apk i have altered 1 at a time..... i do:
Code:
zipalign -f -v 4 E:\app\theapp.apk E:\app\theapp.apk.out

This isnt working for me bc of the .sh after zipalign_apks .. do i rename the zipalign_apks to zipalign_apks.sh after unzipping?
edit:that worked THANKS!

[DEV] Script for tweaks (version 1.02) 18-12-2010

Here is a script i've made (had nothing to do, so...).
Phone must be rooted and have busybox installed.
What first menu looks like:
1 - enable/disable hardware acceleration
2 - enable/disable jit
3 - enable/disable stagefright player
4 - change heapsize
s - show status
r - revert to original configuration
q - quit (don't forget to reboot your phone!)
==================
enter your option:

Download:
http://www.4shared.com/file/gApTB6EG/tweaks.html
md5 b0865d9de67a82215913512cb644211d
Just copy the file to your sdcard. Then in a terminal emulator run:
su
cat /sdcard/tweaks > /data/tweaks
rm /sdcard/tweaks
cd /data/
./tweaks
If it doesn't run, type first:
chmod 755 /data/tweaks
Additional notes:
Script does not work if run from sdcard, must be in /data/ or /system/ (this one goes to allsalvati for testing)
---
If anything is wrong i will fix it, but only if you give me feedback
If you know any good tweaks, say it and i'll add them.
---
Changelog:
version 1.02:
backup/restore added
version 1.01d:
working again. sorry for the mess...
version 1.01c:
nothing new. just rearranging code
version 1.01b:
messages were not staying in output. fixed
version 1.01a:
small fix. v1.01 was not working
version 1.01:
added status menu

what the script does?

So script should be able to do:
enable/disable hw acceleration
enable/disable jit
enable/disable stagefright player
change heapsize

Yes. For now it's what it does.
The ideia is to be able to enable/disable a certain tweak, without reflashing zips, and rewriting files in phone.
But i need some feedback to know if it is working. I can't test it.
It will only change values in /data/local.prop, nothing else.

It seems that it is well written, so I will try that and let you know what's happened.

Thanks for testing. I'm still waiting to have some money so i can buy this phone...
Meanwhile, i'm "playing" with ROMs and files. I'm not good at scripting, but i'm trying to learn while doing something useful.

How much did you increase the heap size?

domenic_s said:

Click to expand...
Click to collapse
I didn't increase it. Script shows this message:
"default=24, recommended=32"
"enter new heapsize value (1-64): "
You can enter any value between 1 and 64.
If you enter any other value, or a string, character, symbol... script will show this message:
"wrong value"
"please input a value between 1 and 64"

For those who don't feel like editing this themselves this is great. Thanks for releasing it for people to try out more tweaks on stock ROMs.

i'm trying to run this script and gives me the following message: ./tweaks: permission denied
Before anything i typed su, then chmod 777 and it gave me error.

It should work be working...
Anyone else confirms this issue? Is this script running or not?
If it is working and there are more tweaks, i can easilly add them to the script.
If this is an isolated case, i really can't help. I don't own an android phone (yet), so i can't test....
allsalvati do you have busybox installed?

No, i don't.
Sent from my LG-P500h using XDA App

That may be your issue.
You must mount /system/ as read-write, then copy busybox binary to /system/xbin/, then run these commands in terminal emulator:
su
cd /system/xbin
/system/bin/chmod 755 busybox
./busybox --install -s /system/xbin
After that you can mount /system/ as read only again, and reboot your phone.
I don't know if there is another way to install it that is easier.

I downladed busybox installer from market and the app says that was installed. The. /tweaks gives me the same message.
How do i test if busybox was installed right?
Sent from my LG-P500h using XDA App

I found this:
That is a problem, you cannot chmod a script to executable on the SD card. (well some things can, but 99% no) the system is designed to prevent u executing scripts from an SD card
cp it to /system/xbin or /system/bin.
Or if u hate to see it in system', use /data/
THEN chmod it. should be fine to run
Click to expand...
Click to collapse
Try to copy the file to /data/ (so you don't mess with /system/), and then try to run it with:
cd /data/
chmod 777 tweaks
./tweaks
It should not need to be run as root

Moved to /data and worked.
I changed heap size to 32 and disabled hardware accelaration just to test.
With hw acc - 981 on Quadrant
Without - 820
So i think this is working.
Perhaps you should print the values so the user can see what is enabled or not before apply.
Thanks for your help
Sent from my LG-P500h using XDA App

Can you test something for me?
Make sure you have hardware acceleration disabled, and reboot you phone.
Then open terminal and run:
getprop | grep hw (see what it outputs)
then run the script, enable hardware acceleration on it, but DON'T reboot your phone yet.
Then exit script, and run again:
getprop | grep hw
Has the value changed, or is it the same?
I need to know if the system assumes immediately any changes (although they may not be functional until reboot).
This is needed to work on your request.

I'll work on that and post an update after someone tries what i asked above.
Thanks for testing
EDIT: to test benchmarks, enable/disable jit. It gives greater differences in values

I tried what you say and both outputs are the same:
$getprop | grep hw
[debug.sf.hw]: [0]
[hw.keyboards.65537.devname]: [7k_handset]
[hw.keyboards.65540.devname]: [thunder_keypad]
[hw.keyboards.65541.devname]: [touch_mcs6000]
[hw.keyboards.65542.devname]: [atcmd_virtual_kbd]
Edit: Tested disabling JIT and it worked. Linpack Before 7.35 - After 4.3

So i can't rely on getprop to check current values...
If anything is changed, getprop won't give the right output till reboot.
Damn... Script was almost updated. Now i must find a new way and redo this section.
Thanks for testing again
EDIT:
New version for download at first post. status menu added.
I think it's all ok.

It seems work fine on my phone. But I can't see the status. When I choose to see current status or status after reboot, the screen of my emulator returns too fast to the selection menu (show curent status or after reboot) and I can't see anything !

[HOW TO?] Install and run 2nd-init for defy

Original post HERE from r2beta0
DANGER!!! Its NOT for Defy! Needs to mobify the 2nd-init first
Hopping some devs to fix it for Defy!
r2beta0 said:
Credit for koush for Droid2 Bootstrap
Credit for edgardcastro for sharing lots of information about 2nd-boot on Milestone1
Credit for Skrilax_CZ for 2nd-init and sh hijack
WARNING: Use this ONLY if you know exactly what you are doing. This guide will make major changes in the /system partition and may turn the phone inoperative. I won’t hold responsibility if you brick your phone or to any damages it may cause.
Pre-requisites: A computer with Android SDK and ADB drivers installed and working. It’s recommended to have RSD Lite 4.9 and the appropriate SBF image just in case anything goes wrong.
This guide was made using a Brazilian Motorola Milestone2 based on Brazil Retail SBF and a computer running Windows Vista 32-bits. I started it from the scratch by flashing my phone with RSD Lite 4.9 and performing a full data/cache wipe, just to make sure any changes were discarded.
Note: Commands that should be entered in command prompt will be listed as: “C:\> <command>”. Commands issued to ADB Shell will be listed as: “# <command>”.
1. Enable USB Debugging on your phone;
2. Get permanent root. I used the app z4root which can be found here on XDA;
3. Install Droid2 Bootstrap. It may be downloaded from Market to support the developer. More info here http://www.koushikdutta.com/2010/08/droid-x-recovery.html;
4. Open Droid2 Bootstrap and click “Bootstrap Recovery”;
5. Use bootstrap to reboot into Clockwork Recovery and backup your phone;
6. Reboot;
7. C:\> adb remount
8. # stop
9. # mkdir /system/etc/rootfs
10. # cp /*.rc /system/etc/rootfs
11. # mkdir /system/etc/init.d
12. # cp /system/bin/sh /system/bin/_sh
13. # cp /init_prep_keypad.sh /system/bin
14. C:\> adb push sh_hijack.sh /system/bin/
15. C:\> adb push 2nd-init /system/bin/
16. C:\> adb push sysinit /system/bin/
17. C:\> adb push sh /system/bin/
18. # chmod 755 /system/bin/sh
19. # chmod 755 /system/bin/sh_hijack.sh
20. # chmod 755 /system/bin/2nd-init
21. # chmod 755 /system/bin/sysinit
22. # ln -s /system/bin/busybox /system/xbin/mount
23. # ln -s /system/bin/busybox /system/xbin/rmdir
24. # ln -s /system/bin/busybox /system/xbin/cp
25. # ln -s /system/bin/busybox /system/xbin/umount
26. # ln -s /system/bin/busybox /system/xbin/run-parts
27. # reboot
28. At this point you should be getting into Clockwork Recovery every time, no matter how many times you have rebooted or if you’ve taken the battery of or not. THIS IS NORMAL. It means that the 2nd-boot + sh hijack is working as it should. The boots into clock recovery are caused by a conflict between sh hijack and logwrapper hijack (used by Droid2 Bootstrap). Continue the guide to fix this issue.
29. In clock recovery menu go to: mounts and storage>mount /system;
30. Open ADB Shell again (it will be available in clockwork recovery as well);
31. # cp /system/bin/logwrapper.bin /system/bin/mylogwrapper
32. C:\> adb pull /system/etc/rootfs/
33. Open init.rc and init.mapphone_umts.rc into a text editor that preserves unix end-line format (e.g.: notepad++). Find all entries of “/system/bin/logwrapper” replacing for “/system/bin/mylogwrapper”.
34. In init.mapphone_umts.rc find entry for “exec /init_prep_keypad.sh” replacing for “exec /system/bin/init_prep_keypad.sh”. Add the following text to the end of this file to be able to run all scripts in /system/etc/init.d at boot time:
Code:
service bootscripts /system/bin/sysinit
class post-zygote_services
disabled
oneshot
35. Save and close.
36. C:\> adb push init.rc /system/etc/rootfs/
37. C:\> adb push init.mapphone_umts.rc /system/etc/rootfs/
38. # chmod 755 /system/etc/rootfs/init.rc
39. # chmod 755 /system/etc/rootfs/init.mapphone_umts.rc
40. Choose “Reboot system now” in clock recovery menu;
You’re all set! Now it is just a matter of changing the rc files in /system/etc/rootfs to customize your system boot.
If you want to log the system boot you may also copy the provided log-init.sh script into /system/etc/rootfs and uncomment the line “exec /log_init.sh” from my init.rc file. Doing so will create the /data/logcat.log file that may get huge in sometime.
2nd-init files and my modified *.rc files attached.
Have fun!

As r2beta0 said for defy porting:
r2beta0 said:
It's very likely, since the 2 devices are very similar. Most of the files I attached are from Milestone1 and works perfectly on MS2. Though I recommend you to NOT replace your *.rc files with the attached ones since they could be not compatible. It would be better if you edit your own files. Also try it ONLY if you have a working version of ClockworkMod Recovery (or other custom recovery). You may adapt this guide for your device and post it here on XDA, just remember to mention my name on credits

Thanks, that looks interesting. I'll look into it later.
Just a big WARNING: if it behaves at it is described on the Defy, DON'T DO THAT, at least not with Tenfar or Kb7sqi 's CWM recovery ports, as booting into Recovery you won't have root adb shell access.

Someone can explain me what is it?

Sent from my Moto Defy using Tapatalk

So, anyone tried? Or is working in that?

So figured I would give this a shot, and well it doesnt work. Phone just sticks at moto logo.
Yes its true in clockwork you cant get root (#) - so I just pulled the .rc files I needed to edit ahead of time and pushed them to the phone before the first reboot. Thus avoiding needing to boot into clockwork after the described bootloop.
If I get time I will play around with this some more.

What is thisss ??

Tip (and question): Use busybox instead of toolbox (ICS)

Hey, guys. I noticed ICS comes with a shell tool called "toolbox" (or maybe it's just my ROM). The traditional tool, called Busybox, is also installed. This tool is much more powerful--if basic shell commands like "mv" don't work properly, toolbox is probably to blame.
Or my system, the shell is mksh and the toolbox tools are installed in /system/bin and busybox is in /system/xbin. Is this the same on all ICS ROMs?
The command to modify the system path so the busybox tools are called preferentially to the toolbox tools is the following:
sed '/: place customisations above this line/i\PATH="/system/xbin:$PATH"' -i /etc/mkshrc
Like I said, I'm assuming my ROM is the same as other ROMs. But the point is to find the shell init file and add PATH="/system/xbin:$PATH" to it. As usual, make a system backup before making changes like this.
In this vein, does anybody know how to change the root user's shell? The "chsh" command doesn't exist on Android, nor does /etc/passwd.

What ROM are you using ?

IceColdSandwich (mostly based on AOKP) - http://forum.xda-developers.com/showthread.php?t=1450962
But is the shell and unix toolchain not common to all ICS builds? I don't know why AOKP and or the makers of this build would have chosen to use tools that are so obviously inferior to the more common tools.
To see which environment/toolchain you are using, check out the symlinks for some shell commands:
# ls -l `which mv`
To see if you have busybox installed:
# which busybox
To test it:
# busybox ls /system
To find which file configures your PATH (determines which executables get called):
# grep -r PATH= /etc
If you find a shell init file, you can edit and add the directory you want to the front of the path:
PATH="/directory/containing/busybox:$PATH"

You can just change the symlinks, with a quick shell script, run from the directory that has everything simlinked to toolbox
Something like:
for i in `busybox --list`
do
mv $i $i.android
ln -s `which busybox` $i
done

I still don't know the usefulness of busybox

[Q] Impossible to use ls -t from BusyBox

Hi,
Sorry if it's not the good forum, I have looked for the good one but I'm not very easy with English.
I want to sort out files by date in directories to delete automatically oldest backup files with a script. I have Cyanogenmod 11 on a Samsung Galaxy S2. I have installed Busybox (Stephen Stericson) on my phone from the Playstore to use the command ls -t because in standard we have only ls and ls -l. But when I tape ls -t, I have an error message "Unknown option". I've tried with Cyanogenmod 12 but I have the same problem.
I would want to know if ls -t doesn't function in BusyBox or if I have another problem.
Thank you.

No response :crying: .
Can somebody tell me if he haves a BusyBox which enables to use the command and which is this BusyBox : ls -t?
Thank you .

Are you sure you are using busybox?
try running: busybox ls -t

Ok, I have to type "busybox" first. I will try it, thank you.

Ok, it works when I add "busybox" in the command . I'm just a little surprised, I had understood the busybox commands replaced the shell commands.

You can also add: busybox sh
to your script and after that you could easily use ls -t without busybox.

Ok, thank you but it's not annoying to add "busybox". I don't create a lot of scripts .
Now I try to solve the problem to move files to the sdcard. It worked fine in 4.1.2 but with Cyanogenmod 11, I have a cross device link. I tried also "cp -p" to keep initial attributes but I have "Operation not permitted".
